Cannot be used in themes.

This option accepts one of the following.

Array of objects
A simple JavaScript array containing a collection of plain objects.
URL
A URL to JSON data or to a service returning data in JSON format.
DataSource or its configuration object
A DataSource is an object that provides a handy API for data processing. A DataSource is a stateful object, which means that it saves data processing settings and applies them each time data is loaded. All underlying data access logic of a DataSource is isolated in a Store. A Store provides an API for reading and modifying data. Unlike the DataSource, a Store is a stateless object.

NOTE

Data field names should not contain the following characters: ., ,, :, [, and ]. Their presence may cause issues in the widget's operation.

elementAttr

Using the size object, you can hide the widget. For this purpose, simply assign 0 to both the height and width of the widget.

NOTE

The size configuration object reserves space for the main widget elements, while displaying a tooltip may require extra space. To reserve the area around the widget for the tooltip, you can apply a margin to the widget's container.

Type:

Default Value: 'generic.light'

A theme is a widget configuration that gives the widget a distinctive appearance. Use can use one of the predefined themes or create a custom one. Changing the option values in the widget's configuration object overrides the theme's corresponding values.

A tooltip is a miniature rectangle displaying widget data. The tooltip appears when the end-user hovers the cursor over the widget. You can enable/disable the tooltip, change its appearance and format its text using fields of the tooltip configuration object.

NOTE

The tooltip is displayed outside the widget's container. If you plan to use the tooltip, make sure there is enough space around your widget to display it. For example, you can apply a margin to the widget's container to reserve the area around the widget for the tooltip.
