Chart Advanced Features: Pie 2D

The following sections provide a list of available advanced attributes available for controlling and customizing 2D Pie 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 etc. You can also set chart limits and extended properties.

AttributeTypeValueDescription
animationTrue/False0/1This 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.
animationDurationNumberIn secondsThis attribute sets the animation duration of the chart. `animationDuration` attribute is applicable only if animation of the chart is enabled.
Default value: 1 sec
animateClockwiseTrue/False0/1Animates the plot in clockwise direction.
Default value: 0
alphaAnimationTrue/False0/1Instead of rotational animation, you can set alpha animation which displays your chart slowly from `0` alpha to `100`.
Default value : 0
paletteNumber1-5Exago 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.
paletteColorsTextList of hex color codes separated by commaWhile 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.
showZeroPiesTrue/False0/1Configuration whether to show pies with 0 values (and their values). Otherwise, they won’t show up in the chart.
showPercentValuesTrue/False0/1Whether to show percentage values in labels of the chart.
showPercentInToolTipTrue/False0/1Whether to show percentage values in tool tip.
showLabelsTrue/False0/1Whether to show labels on the chart.
showValuesTrue/False0/1Whether to show values on the chart.
labelSepCharTextCharacterThe character to separate the data label and data values on the chart.
clickURLTextAnyThe 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.
clickURLOverridesPlotLinksTrue/False0/1Sets 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`)
useDataPlotColorForLabelsTrue/False0/1Uses the same data plot color for data labels.
hasRTLTextNumberAnyThis 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.
plotHighlightEffectTextAnyThis 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`
showPrintMenuItemTrue/False0/1Whether 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.
themeText‘fusion’, ‘gammel’, ‘candy’, ‘ocean’, ‘zune’, ‘carbon’, ‘umber’This attribute changes the theme of the chart. There are 7 types of themes which have been made according to the different color combinations.

Pie / Doughnut Properties

The following attributes let you control various functionalities of pie/doughnut chart.

AttributeTypeValueDescription
radius3DNumber0-100You can define the 3D Radius of chart in percentage using this attribute. It basically helps you set the bevel distance for the pie/doughnut (if in 3D Lighting Mode).
pieRadiusNumberIn Pixels & PercentageThis attribute lets you explicitly set the outer radius of the chart. Exago automatically calculates the best fit pie radius for the chart. This attribute is useful if you want to enforce one of your own values. Starting v3.14.0, you can specify the radius of a pie chart in both percentage and pixel values.
startingAngleNumber0-360By default, the pie chart starts from angle 0 degree i.e., the first pie slice starts plotting from 0 degree angle. If you want to change the starting angle of the chart, use this attribute. It obeys the conventions of co-ordinate geometry where 0 degrees means hand of a clock at 3. Starting angle Increases anti-clockwise.
enableSlicingTrue/False0/1This attribute specifies whether slicing of the data plots should be enabled for pie/doughnut charts. Setting this attribute to `1` will enable slicing for the chart, setting it to `0` will disable slicing.
Default value: 1
slicingDistanceNumberIn PixelsIf you’ve opted to slice a particular pie/doughnut slice, using this attribute you can control the distance between the slice and the center of chart.
enableRotationTrue/False0/1The pie charts have three modes: Slicing, Rotation, and Link. By default, a chart starts in Slicing mode. If you need to enable rotation from XML, set this attribute to 1. But, when links are defined, the chart always works in Link mode irrespective of the value of this attribute.
enableMultiSlicingTrue/False0/1This attribute specifes whether single-slicing for the data plots should be enabled for pie/doughnut charts. Setting this attribute to `0` will enable single-slicing for the chart, setting it to `1` will enable multi-slicing.
Default value: 1

Smart Labels & Lines

In Exago, the pie and doughnut charts can now have smart labels and lines. Smart labels/lines are data connector lines which connect the pie/doughnut slices to their respective labels without over-lapping even in cases where there are lots of labels located near each other. You can configure the smart labels/lines properties using the attributes below.

AttributeTypeValueDescription
enableSmartLabelsTrue/False0/1Whether to use smart labels or not.
skipOverlapLabelsTrue/False0/1Whether to skip labels that are overlapping even when using smart labels. If not, they might overlap if there are too many labels.
isSmartLineSlantedTrue/False0/1The smart lines (smart label connector lines) can appear in two ways: Slanted or Straight. This attribute lets you choose between them.
smartLineColorColorHex Color CodeColor of smart label connector lines.
smartLineThicknessNumberIn PixelsThickness of smart label connector lines.
smartLineAlphaNumber0 – 100Alpha of smart label connector lines.
labelDistanceNumberIn PixelsThis attribute helps you set the distance of the label/value text boxes from the pie/doughnut edge. This attribute will work only when the attribute `enableSmartLabels` is set to ‘0’.
manageLabelOverflowTrue/False0/1This attribute tries to manage overflow of data labels. If enabled, data labels are either wrapped or truncated with ellipses to prevent them from overflowing out of the chart canvas. In case `smartLabels` is disabled, the labels are wrapped to avoid the overflow. Since `smartLabels` is disabled, the wrapped labels might get overlapped. When `smartLabels` is enabled, management of the overflowing labels fit in the “quadrant specific smart labeling algorithm”. Data labels try to wrap first. In case, there is a space constraint in the quadrant, the labels get truncated with ellipses.
useEllipsesWhenOverflowTrue/False0/1When enabled, long data labels are truncated by adding ellipses to prevent them from overflowing the chart background. The default value is 1. This setting works only when `manageLabelOverflow` is set to 1.
labelPositionTextOutside, InsideThis attribute places the data labels outside/inside of the pie slices.
Default value: Outside
valuePositionTextOutside, InsideThis attribute places the data values outside/inside of the pie slices.
Default value: Outside
minAngleForLabelNumber0 – 360Set the minimum angle for a pie slice, above which the data labels will be visible, provided `labelPosition` is set to `inside`.
Default value: 0
minAngleForValueNumber0 – 360Set the minimum angle for a pie slice, above which the data values will be visible, provided `valuePosition` is set to `inside`.
Default value: 0

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

AttributeTypeValueDescription
formatNumberTrue/False0/1This 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’;.
formatNumberScaleTrue/False0/1Configuration whether to add K (thousands) and M (millions) to a number after truncating and rounding it – e.g., if `formatNumberScale` is set to 1, 1043 will become 1.04K (with decimals set to 2 places). Same with numbers in millions – an M will be added at the end.
defaultNumberScaleTextAnyThe default unit of the numbers that you’re providing to the chart.
numberScaleUnitTextAnyUnit of each block of the scale.
numberScaleValueTextAnyRange of the various blocks that constitute the scale.
forceNumberScaleTrue/False0/1If 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`.
scaleRecursivelyTrue/False0/1Whether recursive scaling should be applied.
maxScaleRecursionNumberAnyHow many recursions to complete during recursive scaling? -1 completes the entire set of recursion.
scaleSeparatorTextAnyWhat character to use to separate the scales that are generated after recursion?
numberPrefixTextCharacterUsing 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.
numberSuffixTextCharacterUsing this attribute, you could add a suffix 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.
decimalSeparatorTextCharacterThis attribute helps you specify the character to be used as the decimal separator in a number.
thousandSeparatorTextCharacterThis attribute helps you specify the character to be used as the thousands separator in a number.
thousandSeparatorPositionNumber This option helps you specify the position of the thousand separator.
inDecimalSeparatorTextCharacterIn 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.
inThousandSeparatorTextCharacterIn 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.
decimalsNumber0-10Number of decimal places to which all numbers on the chart will be rounded to.
forceDecimalsTrue/False0/1Whether to add 0 padding at the end of decimal numbers. For example, if you set decimals as 2 and a number is 23.4. If forceDecimals is set to 1, Exago will convert the number to 23.40 (note the extra 0 at the end).

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.

interactiveLegendTrue/False0/1This attribute lets you interact with the legend in your chart. When you click a particular legend key, the associated slice slides out from the chart. Re-clicking the key causes the slice to slide in.
legendNumColumnsNumberZero and Positive IntegersThe legend items are arranged in columns. Using this attribute, you can propose the number of columns. This value undergoes internal checking on judicious use of white-space. In case, the value is found improper, the chart auto-calculates the number of columns. When set to 0, the chart automatically decides the number of columns. The above is applicable when `legendPosition` is set to BOTTOM`.` If you have set RIGHT `legendPosition`, the number of columns is always set to 1.

Toolbar Attributes

Using this set of attributes, you can customize the toolbar on the chart. The advantage of having a toolbar is that it manages all the UI action elements (context menus, checkboxes, buttons) centrally. This provides a clean, uniform look and a better, more meaningful and logical grouping.

AttributeTypeValueDescription

Default value: download

exportHandlerTextAnyIn case of server side exporting, this refers to the path of the server-side export handler (the ready-to-use scripts that we provide).
exportFormatsTextAnyLets you configure what output formats to allow for export of chart, in the export context menu, and also customize the label for each menu item. The attribute value should be a pipe (|) delimited separated key-value pair. Example: `exportFormats: ‘PNG=Export as High Quality Image|JPG|PDF=Export as PDF File’`
exportModeTextAnyThis attributes sets the modes of export. To enable client-side exporting, set this attribute to `client`.

Default value: auto.

Note: Starting v3.12.1, the `exportMode` attribute replaces the `exportAtClientSide` attribute. However, you don’t need to make any changes to the existing setup because, the Exago library comes with the proper mapping already provided.

exportShowMenuItemTrue/False0/1Whether the menu items related to export (e.g., Save as JPEG etc.) will appear in the context menu of chart.
exportTargetWindowText‘_self’ or ‘_blank’In case of server-side exporting and when using download as action, this lefts you configure whether the return image, PDF, SVG or XLSX will open in same window (as an attachment for download), or whether it will open in a new window.

Data Plot Hover Effects

If you wish to show an effect on the data plot (column, line anchor, pie etc.) when the user hovers his mouse over the data plot, these attributes let you configure the cosmetics of the hover for all data plots in the chart.

AttributeTypeValueDescription

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. 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.

AttributeTypeValueDescription
captionPaddingNumberIn PixelsThis attribute lets you control the space (in pixels) between the sub-caption and top of the pie. If the sub-caption is not defined, it controls the space between caption and top of the pie. If neither caption, nor sub-caption is defined, this padding does not come into play.
chartLeftMarginNumberIn PixelsAmount of empty space that you want to put on the left side of your chart. Nothing is rendered in this space.
chartRightMarginNumberIn PixelsAmount of empty space that you want to put on the right side of your chart. Nothing is rendered in this space.
chartTopMarginNumberIn PixelsAmount of empty space that you want to put on the top of your chart. Nothing is rendered in this space.
chartBottomMarginNumberIn PixelsAmount of empty space that you want to put at the bottom of your chart. Nothing is rendered in this space.

The data Object

In single-series charts, each instance of the `data` object represents a data value to be plotted on the chart. For a single-series chart, one instance of the `data` object looks as shown in the example below:


"data"[{
		"label": "Jan",
		"value": "10000"
	}]

Attributes of the `data` object are used to set and configure the data values for the chart.

AttributeTypeValueDescription
alphaNumber0 – 100This attribute determines the transparency of a data item. The range for this attribute is 0 to 100. 0 means complete transparency (the data item wont be shown on the graph) and 100 means opaque.
borderAlphaColorHex Color CodeIf you want to set border alpha of individual pie/doughnut data items, you can specify using this attribute.
borderColorColorHex Color CodeIf you want to set border color of individual pie/doughnut data items, you can specify using this attribute.

linkTextAnyYou 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.
