Chart Advanced Features: Doughnut 2D

The following sections provide a list of available advanced attributes available for controlling and customizing 2D Doughnut chart elements.

This topic contains documentation for advanced attributes which are third-party customizations that must be manually entered into the chart wizard. These topics 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.

Chart Message-related Attributes

These attributes let you set and configure custom chart messages, using text as well as images.

Chart Titles

Using these attributes, you can set the various headings and titles of chart like caption and sub-caption.

Chart Caption Cosmetics

These attributes let you configure the cosmetics of chart caption and sub-caption.

Chart Cosmetics

The following attributes let you configure chart cosmetics like background color, background alpha etc.

Data Plot Cosmetics

These attributes let you configure how your plot (columns, lines, area, pie or any data that you’re plotting) will appear on the chart. If the plots can show borders, you can control the border properties using the attributes listed below. Or, if they support gradient fills, you can again configure various properties of the gradient using these attributes. Various other controls over plot cosmetics can be attained using this set of attributes.

Pie / Doughnut Properties

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

Smart Labels & Lines

In Exago BI, 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.

Number Formatting

Exago BI 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

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 BI. Using Styles, you can also specify advanced font properties like Bold, Italics, HTML Mode etc.

Data Label Cosmetics

These attributes let you configure the cosmetics of all data labels of the chart.

Center Label Cosmetics

These attributes let you configure the cosmetics of the center label of the chart.

Legend Properties

In pie / doughnut charts, the name of each slice shows up in the legend of the chart. If you do not need the legend, you can opt to hide the same. Also, the legend can be placed at the bottom of the chart or to the right of the chart. Using the attributes below, you can configure the functional and cosmetic properties of the legend.

Tool tip Attributes

These attributes let you control the tool tip. You can set the background color, border color, separator character and few other details.

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.

Attributes for Exporting Charts

These attributes allow you to control the saving of chart as image, SVG or XLSX.

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.

Chart Padding & Margins

The following attributes help you control chart margins and padding. Exago BI 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 BI will not plot anything in that space. It’s not necessary for you to specify any padding/margin values. Exago BI automatically assumes the best values for the same, if you do not specify the same.

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.
