Chart Advanced Features: Stacked Bar 3D
The following sections provide a list of available advanced attributes available for controlling and customizing Stacked Bar 3D chart elements.
Note: This article contains documentation for advanced attributes which are third-party customizations that must be manually entered into the chart wizard. These articles were converted directly from the documentation provided by this third-party source. Not every attribute listed may be supported in Exago BI as some unexpected conflicts may occur in their integration within the application.
Functional Attributes
These attributes let you control a variety of functional elements on the chart. For example, you can opt to show/hide data labels, data values. You can also set chart limits and extended properties.
| Attribute | Type | Value | Description |
| animation | True/False | 0/1 | This attribute gives you the option to control animation in your charts. If you do not want to animate any part of the chart, set this as 0. |
| animationDuration | Number | In seconds | This attribute sets the animation duration, if `animation` is set to `1`. Default value: 1 sec |
| palette | Number | 1-5 | Exago uses the concept of Color Palettes. Each chart has 5 pre-defined color palettes which you can choose from. Each palette renders the chart in a different color theme. |
| paletteColors | Text | List of hex color codes separated by comma | While the `palette` attribute allows to select a palette theme that applies to chart background, canvas, font and tool-tips, it does not change the colors of data items (i.e., column, line, pie etc.). Using `paletteColors` attribute, you can specify your custom list of hex colors for the data items. The list of colors have to be separated by comma e.g., `”paletteColors”: “#FF0000, #0372AB, #FF5904…”`. The chart will cycle through the list of specified colors and then render the data plot accordingly. To use the same set of colors throughout all your charts in a web application, you can store the list of palette colors in your application globally and then provide the same in each chart JSON. |
| showLabels | True/False | 0/1 | It sets the configuration whether the x-axis labels will be displayed or not. |
| labelStep | Number | 1 or above | By default, all the labels are displayed on the chart. However, if you’ve a set of streaming data (like name of months or days of week), you can opt to show every n-th label for better clarity. This attribute just lets you do so. When a value greater than 1 (n) is set to this attribute, the first label from left and every label at the n-th position from left will be displayed. e.g., a chart showing data for 12 months and set with `labelStep: 3` will show labels for January, April, July, and October. The rest of the labels will be skipped. |
| maxLabelWidthPercent | Number | 1-100 | Restricts the maximum length of data labels in terms of percentage of the charts width that the data labels can occupy. If a data label is longer than the specified percentage width then it will either be wrapped or get truncated, subject to availability of vertical space. Unnecessary space is not reserved for the data labels, in case all of them are shorter than the specified maximum width. |
| minLabelWidthPercent | Number | 1-100 | Restricts the minimum length of data labels in terms of percentage of the chart’s width that the data labels can occupy. The space thus calculated stays reserved even if the label width is less than the minimum width. |
| useEllipsesWhenOverflow | True/False | 0/1 | This attribute lets you set whether the overflowing data labels will be truncated by adding ellipses. |
| showValues | True/False | 0/1 | Sets the configuration whether data values will be displayed along with the data plot on chart. |
| maxBarHeight | Number | In Pixels | Sets the maximum allowed bar height. |
| clickURL | Text | Any | The entire chart can now act as a hotspot. Use this URL to define the hotspot link for the chart. The link can be specified in Exago Link format. |
| clickURLOverridesPlotLinks | True/False | 0/1 | Sets whether the `clickURL` attribute (that sets a link to which the user is directed when the chart is clicked) overrides the `link` attribute (that sets a link to which the user is directed when a data plot is clicked). Default value: 0 (`clickURL` does not override `link`) |
| showShadow | True/False | 0/1 | Whether to apply the shadow effects for data plot. |
| adjustDiv | True/False | 0/1 | Exago automatically tries to adjust divisional lines and limit values based on the data provided. However, if you want to set your explicit lower and upper limit values and number of divisional lines, first set this attribute to false. That will disable automatic adjustment of divisional lines. |
| use3DLighting | True/False | 0/1 | Whether to use advanced gradients and shadow effects to create better looking 3D charts. |
| showSum | True/False | 0/1 | Whether to show the sum of each stacked bar along its side. |
| stack100Percent | True/False | 0/1 | Setting this attribute to 1 helps in depicting the values in percentage figures. |
| showPercentValues | True/False | 0/1 | Whether to show percentage figures in data values of the chart. |
| showPercentInToolTip | True/False | 0/1 | Whether to show percentage figures in tool tip. |
| hasRTLText | Number | Any | This attribute, when set to `1`, indicates to the chart that the text (rendered on the chart) may contain RTL characters and the textual display has to be managed accordingly. |
| plotHighlightEffect | Text | Any | This attribute lets you enable/disable the highlight effect, in the form of a `fadeout`, for the data plots corresponding to a legend item. When this attribute is enabled and the mouse pointer is hovered over a legend item label, plots belonging to the other data series fadeout, by reducing their opacity. The fadeout effect can be customized by specifying the fadeout color and opacity using the `color` and `alpha` attributes. Eg. `fadeout|color=#ff0000, alpha=60` |
| showPrintMenuItem | True/False | 0/1 | Whether to show “Print Chart” item in the context menu of the chart? Even if you opt to hide the item in context menu, you can still opt to invoke `print()` JavaScript method of the chart to print the same. |
| theme | Text | ‘carbon’, ‘fint’, ‘ocean’, ‘zune’ | This attribute changes the theme of the chart. There are 4 types of themes which have been made according to the different color combinations. |

Number Formatting
Exago offers you a lot of options to format your numbers on the chart. Using the attributes below, you can control a myriad of options like: Formatting of commas and decimals Number prefixes and suffixes Decimal places to which the numbers will round to Scaling of numbers based on a user defined scale Custom number input formats
| Attribute | Type | Value | Description |
| formatNumber | True/False | 0/1 | This configuration determines whether the numbers displayed on the chart will be formatted using commas, e.g., 40,000 if ‘formatNumber’: ‘1’; and 40000 if ‘formatNumber’: ‘0’;. |
| formatNumberScale | True/False | 0/1 | Configuration whether to add K (thousands) and M (millions) to a number after truncating and rounding it – e.g., if `formatNumberScale` is set to 1, 10434 will become 1.04K (with decimalPrecision set to 2 places). Same with numbers in millions – an M will be added at the end. |
| defaultNumberScale | Text | Any | The default unit of the numbers that you’re providing to the chart. |
| numberScaleUnit | Text | Any | Unit of each block of the scale. |
| numberScaleValue | Text | Any | Range of the various blocks that constitute the scale. |
| forceNumberScale | True/False | 0/1 | If a data value is less than the lowest given number is the number scale, this attribute forces the lower value of the `numberScaleUnit` to be applied to that data value. This attribute works only when `“formatNumberScale”: “1”` and the `defaultNumberScale` attribute is not defined. For example, if `“numberScaleUnit”: “K, M”`, `“numberScaleValue”: “1000, 1000”`, and `“forceNumberScale”: “1”`, a data value of `400` will be rendered as `0.40K`. |
| scaleRecursively | True/False | 0/1 | Whether recursive scaling should be applied. |
| maxScaleRecursion | Number | Any | How many recursions to complete during recursive scaling? -1 completes the entire set of recursion. |
| scaleSeparator | Text | Any | What character to use to separate the scales that are generated after recursion? |
| numberPrefix | Text | Character | Using this attribute, you could add prefix to all the numbers visible on the graph. For example, to represent all dollars figure on the chart, you could specify this attribute to $ to show like $40000, $50000. |
| numberSuffix | Text | Character | Using this attribute, you could add prefix to all the numbers visible on the graph. For example, to represent all figures quantified as per annum on the chart, you could specify this attribute to ‘/a’ to show like 40000/a, 50000/a. |
| decimalSeparator | Text | Character | This attribute helps you specify the character to be used as the decimal separator in a number. |
| thousandSeparator | Text | Character | This attribute helps you specify the character to be used as the thousands separator in a number. |
| thousandSeparatorPosition | Number | This option helps you specify the position of the thousand separator. | |
| inDecimalSeparator | Text | Character | In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, Exago accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the decimal separator. |
| inThousandSeparator | Text | Character | In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, Exago accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the thousand separator. |
| decimals | Number | 0-10 | Number of decimal places to which all numbers on the chart will be rounded to. |
| forceDecimals | True/False | 0/1 | Whether to add 0 padding at the end of decimal numbers. For example, If you limit the maximum number of decimal digits to 2, a number like 55.345 will be rounded to 55.34. This does not mean that all numbers will be displayed with a fixed number of decimal places. For instance 55 will not be displayed as 55.00 and 55.1 will not become 55.10. In order to have fixed number of decimal places attached to all the numbers, set this attribute to 1. |
Font Properties
Using the attributes below, you can define the generic font properties for all the text on the chart. These attributes allow you a high level control over font properties. If you intend to specify font properties for individual chart elements (like Caption, sub-caption etc.), you’ll need to use the Styles feature of Exago. Using Styles, you can also specify advanced font properties like Bold, Italics, HTML Mode etc.

| plotBorderHoverThickness | Number | In Pixels | Sets the thickness of the border of plot when hovered. |
Chart Padding & Margins
The following attributes help you control chart margins and paddings. Exago allows you to manually customize the padding of various elements on the chart to allow advanced manipulation and control over chart visualization. Padding in Exago is always defined in pixels, unless the attribute itself suggests some other scale (like `plotSpacePercent`, which configures the spacing using percentage values). You can also define the chart margins. Chart Margins refer to the empty space left on the top, bottom, left and right of the chart. That means, Exago will not plot anything in that space. It’s not necessary for you to specify any padding/margin values. Exago automatically assumes the best values for the same, if you do not specify the same.
| Attribute | Type | Value | Description |
| captionPadding | Number | In Pixels | This attribute lets you control the space (in pixels) between the sub-caption and top of the chart canvas. If the sub-caption is not defined, it controls the space between caption and top of chart canvas. If neither caption, nor sub-caption is defined, this padding does not come into play. |
| xAxisNamePadding | Number | In Pixels | Using this, you can set the distance between x-axis title and canvas end. |
| yAxisNamePadding | Number | In Pixels | Using this, you can set the distance between the y-axis title and y-axis values. |
| yAxisValuesPadding | Number | In Pixels | This attribute helps you set the vertical space between the canvas bottom edge and the y-axis values. This is particularly useful, when you want more space between your canvas and y-axis values. |
| labelPadding | Number | In Pixels | This attribute sets the horizontal space between the labels and canvas left edge. If you want more space between the canvas and the x-axis labels, you can use this attribute to control it. |
| plotSpacePercent | Number | 0-80 (In Percent) | On a column chart, there is spacing defined between two columns. By default, the spacing is set to 20% of canvas width. If you intend to increase or decrease the spacing between columns, you can do so using this attribute. For example, if you wanted all columns to stick to each other without any space in between, you can set `plotSpacePercent` to 0. Similarly, if you want very thin columns, you can set `plotSpacePercent` to its max value of 80. |
| chartLeftMargin | Number | In Pixels | Amount of empty space that you want to put on the left side of your chart. Nothing is rendered in this space. |
| chartRightMargin | Number | In Pixels | Amount of empty space that you want to put on the right side of your chart. Nothing is rendered in this space. |
| chartTopMargin | Number | In Pixels | Amount of empty space that you want to put on the top of your chart. Nothing is rendered in this space. |
| chartBottomMargin | Number | In Pixels | Amount of empty space that you want to put at the bottom of your chart. Nothing is rendered in this space. |
| canvasPadding | Number | In Pixels | Allows you to set empty space on the top and bottom side of bars on the chart canvas |
| legendPadding | Number | In Pixels | Padding of legend from right/bottom side of canvas |
| canvasLeftMargin | Number | In Pixels | This attribute lets you control the space between the start of chart canvas and the start (x) of chart. In case of 2D charts, the canvas is the visible rectangular box. In case of 3D charts, the canvas box is the imaginary box around the 3D canvas. Using this attribute, you can control the amount of empty space between the chart left side and canvas left side. By default, Exago automatically calculates this space depending on the elements to be placed on the chart. However, if you want to over-ride this value with a higher value, you can use this attribute to specify the same. Please note that you cannot specify a margin lower than what has been calculated by the chart. This attribute is particularly useful, when you’ve multiple charts placed in a page and want all their canvas start position to align with each other – so in such a case, you can set same margin value (a value large enough that it doesn’t get rejected by chart owing to it being lower than the calculated value) for all such charts in the page. |
| canvasRightMargin | Number | In Pixels | Like `canvasLeftMargin`, this attribute lets you set the space between end of canvas and end of chart. |
| canvasTopMargin | Number | In Pixels | Like `canvasLeftMargin`, this attribute lets you set the space between top of canvas and top of chart. |
| canvasBottomMargin | Number | In Pixels | Like `canvasLeftMargin`, this attribute lets you set the space between bottom of canvas and bottom of chart. |
The categories Object
The `categories` object and the `category` object (child of the `categories` object) are used to specify x-axis labels for multi-series charts. The attributes of the `categories` object are used to set the font properties of all x-axis labels collectively.

| toolText | Text | Any | The tooltip defined in the `category` object appears only when the mouse cursor is hovered over the data plots. However, this will not appear when the cursor is moved over the data labels (except for a situation when long labels are automatically truncated with ellipses. In this situation, if the mouse cursor is hovered over a truncated label, the tooltip will appear with the full label). In case you want to set a short label and show the full label in tooltip, define the full label using this attribute within the `category` object. The tooltip with the full label will appear only when the mouse is hovered on the dataplot. |

| borderDashGap | Number | In pixels | Sets the gap between two consecutive dashes when the border around x-axis label is rendered using dashed lines. |
Vertical Data Separator Lines
Vertical data separator lines help you separate data blocks. These lines run through the height of the chart, thereby segregating the data into two different blocks. Vertical lines are defined as shown in the example below:
"categories": [{
"category": [{
"label": "Grade 1",
},
{
"vLine": "true",
"label": "Appraisal"
}]
}]
You can configure the cosmetics of vertical separator lines using the following attributes:

| dashGap | Number | In pixels | Sets the gap between consecutive dashes when vertical separator line is rendered as dashed lines. |
| label | Text | Label for the vertical separator line, if to be shown.
Note: The `label` attribute replaces the `name` attribute. Previously, either one of the attributes could be used to set the label. Support for the `name` attribute has been discontinued since v3.10.0. |
|
| showLabelBorder | True/False | 0/1 | Whether to show a border around the vLine label. |
| linePosition | Number | 0-1 | Helps configure the position of vertical line i.e., if a vLine is to be plotted between 2 points Jan and Feb, user can set any position between 0 and 1 to indicate the relative position of vLine between these two points (0 means Jan and 1 means Feb). By default, it’s 0.5 to show in between the points. |
| labelPosition | Number | 0-1 | Helps configure the position of the vLine label by setting a relative position between 0 and 1. In vertical charts, 0 means top of canvas and 1 means bottom. In horizontal charts, 0 means left of canvas and 1 means right. |
| labelHAlign | Text | left, center, right | Horizontal anchor point for the alignment of vLine label. |
| labelVAlign | Text | top, middle, bottom | Vertical anchor point for the alignment of vLine label. |
The dataset Object
Each `dataset` object contains a series of data. For example, for a monthly sales comparison chart for two successive years, the first data-set would contain the data for first year and the next one for the second year. You can provide data-set level cosmetics so that all data within that data-set will be plotted in the same color/alpha/etc. Depending on the chart type, there are a number of attributes that you can define for each `dataset` object.
| Attribute | Type | Value | Description |
| seriesName | Text | Any | Lets you specify the series name for a particular dataset. For example, if you’re plotting a chart to indicate monthly sales analysis for 2005 and 2006, the `seriesName` for the first dataset will be 2005 and that of the second will be 2006. The `seriesName` of a dataset is shown in legend. |
| color | Color | Hex Color Code | This attribute sets the color using which columns, lines, area of that dataset will be drawn |
| alpha | Text | 0 – 100 or Comma Separated List | This attribute sets the alpha (transparency) of the entire dataset. |

The data Object
Attributes of the `data` object, child of the `dataset` object, are used to define the values to be plotted for individual data series. The `dataset` and `data` objects defined for one data series are shown in the example below:
"dataset": [{
"seriesname": "Previous Year",
"data": [{
"value": "10000",
},
{
"value": "11500",
},
{
"value": "12500",
},
{
"value": "15000"
}]
}]
| Attribute | Type | Value | Description |
| showValue | True/False | 0/1 | You can individually opt to show/hide values of individual data items using this attribute. This value over-rides the dataset level value. |
| alpha | Number | 0 – 100 | For stacked charts, you can define the alpha of datasets at dataset level. However, if you wish to highlight a particular data element, you can specify its alpha at “set” level using this attribute. |
| value | Number | Any | Numerical value for the data item. This value will be plotted on the chart. |
| displayValue | Text | If instead of the numerical value of this data, you wish to display a custom string value, you can specify the same here. Examples are annotation for a data item etc. | |
| toolText | Text | Any | By default, Exago shows the series name, category name, and value as tool tip text for that data item. But, if you want to display more information for the data item as tool tip, you can use this attribute to specify the same. |
| color | Color | Hex Color Code | For stacked charts, you can define the color of datasets at dataset level. However, if you wish to highlight a particular data element, you can specify its color at “set” level using this attribute. |
| link | Text | Any | You can define links for individual data items. That enables the end user to click on data items (columns, lines, bars etc.) and drill down to other pages. To define the link for data items, use the link attribute. You can define links that open in same window, new window, pop-up window or frames. Please see “Drill-Down > Using JavaScript Functions as Links” for more information. Also, you’ll need to Url Encode all the special characters (like ? and &) present in the link. |
| hoverColor | Color | Hex Color Code | This attribute can set the hover color for a particular data plot. |
| hoverAlpha | Number | 0 – 100 | This attribute sets the transparency for a particular data plot when hovered. |
| borderHoverColor | Color | Hex Color Code | This attribute sets the border color of a particular data plot on hover. |
| borderHoverAlpha | Number | 0 – 100 | This attribute sets the border’s transparency for a particular data plot on hover. |
| borderHoverThickness | Number | In pixels | This attribute sets the thickness for a data plot’s border on hover. |
Trend-lines
Trend-lines are horizontal lines that aid in interpretation of data with respect to some pre-determined value. For example, if you are plotting the sales data for the current year, you might want to show the previous year’s average monthly sales as a trend indicator for ease of comparison. The `lines` object, child of the `trendlines` object is used to add trend-lines to a chart. Although the `line` object has to be defined within the `trendlines` object, the latter cannot be used to collectively customize trend-lines, because it does not have any attributes of its own. The attributes of the `lines` object, child of the `trendlines` object, are used to create and customize trend-lines for charts.
| Attribute | Type | Value | Description |
| startValue | Number | Numeric Value | The starting value for the trendline. Say, if you want to plot a slanted trendline from value 102 to 109, the `startValue` will be 102. |
| endValue | Number | Numeric Value | The ending y-axis value for the trendline. Say, if you want to plot a slanted trendline from value 102 to 109, the `endValue` will be 109. If you do not specify a value for `endValue`, it will automatically assume the same value as `startValue`. |
| displayValue | Text | Any | If you want to display a string caption for the trend line by its side, you can use this attribute. Example: `displayValue=’Last Month High’`. When you don’t supply this attribute, it automatically takes the value of `startValue`. |
| color | Text | Hex Color Code | Color of the trend line and its associated text |
| isTrendZone | True/False | 0/1 | Whether the trend will be displayed as a line or a zone (fill-colored rectangle). |
| thickness | Number | In Pixels | If you’ve opted to show the trend as a line, this attribute lets you define the thickness of trend line. |
| alpha | Number | 0 – 100 | Alpha of the trend line. |
| dashed | True/False | 0/1 | Whether the trendline should be rendered as dashed lines.
Default value: 0 (trendline rendered using straight lines) |
| dashLen | Number | In pixels | Sets the width of each dash when trendline is rendered as dashed lines. |
| dashGap | Number | In pixels | Sets the gap between consecutive dashes when trendline is rendered as dashed lines. |
| toolText | Text | Custom tool-text for this trendline/zone. |
Trend-lines (Chart level attributes)
Trend-lines are horizontal lines that aid in interpretation of data with respect to some pre-determined value. For example, if you are plotting the sales data for the current year, you might want to show the previous year’s average monthly sales as a trend indicator for ease of comparison. Cosmetics for all the trend-lines rendered can be attained using this set of attributes. Although there are set of attributes of the `line object`, used to create and customize trend-lines, these set of attributes effect all the trend-lines rendered in your chart.
| Attribute | Type | Value | Description |
| trendlineColor | Color | Hex Color Code | Sets color of all the trend lines and its associated text in the chart. |
| trendlineThickness | Number | In Pixels | If you’ve opted to show the trend as a line, this attribute lets you define the thickness of all the trend lines in your chart. |
| trendlineAlpha | Number | 0 – 100 | Sets transparency for all the trend lines in your charts. |
Trend-lines Display Value Cosmetics
These attributes let you customize the text displayed with a trend-line.
Note: These attributes belong to the `chart` object and not to the `line` object (child of the `trendline` object). They are, therefore, applied to all trend-lines on your chart.
| Attribute | Type | Value | Description |
| trendValueFont | Text | Font Name | Sets the font family for the trend-line display value. |
| trendValueFontSize | Number | Sets the font size for the trend-line display value. | |
| trendValueFontBold | True/False | 0/1 | Sets whether the trend-line display value will be bold formatted. Default value: 0 (not bold formatted) |
| trendValueFontItalic | True/False | 0/1 | Sets whether the trend-line display value will be italicized. Default value: 0 (not italicized) |
| trendValueBgColor | Color | Hex Color Code | Sets the background color for the trend-line display value. |
| trendValueBorderColor | Color | Hex Color Code | Sets the border color for the trend-line display value. |
| trendValueAlpha | Number | 0 – 100 | Sets the transparency for the trend-line display value. Default value: 100 |
| trendValueBgAlpha | Number | 0 – 100 | Sets the transparency for the background of the trend-line display value. Default value: 100 |
| trendValueBorderAlpha | Number | 0 – 100 | Sets the transparency for the border around the trend-line display value. Default value: 100 |
| trendValueBorderPadding | Number | In pixels | Sets padding for the border around the trend-line display value. |
| trendValueBorderRadius | Number | In pixels | Sets the radius for the border around the trend-line display value. |
| trendValueBorderThickness | Number | In pixels | Sets the thickness for the border around the trend-line display value. |
| trendValueBorderDashed | True/False | 0/1 | Whether the border around the trend-line display value should be rendered as dashed lines.
Default value: 0 (border rendered using straight lines) |
| trendValueBorderDashLen | Number | In pixels | Sets the length of each dash when the border around the trend-line display value is rendered as dashed lines. |
| trendValueBorderDashGap | Number | In pixels | Sets the gap between two consecutive dashes when the border around the trend-line display value is rendered as dashed lines. |
