ui.igBaseChart

This is the base widget for igSparkline, igFunnelChart, and igDoughnutChart. It contains options, methods, events, and CSS classes implemented by the derived widgets. It must be inherited and when using igBaseChart example code, you should replace igBaseChart with the actual chart widget used.

Code Sample

// See specific members for more details or see derived widgets: igSparkline, 
// igFunnelChart, or igDoughnutChart for implementation overview.

For more information on how to interact with the Ignite UI controls' events, refer to
Using Events in Ignite UI.

Note: Calling API methods programmatically does not raise events related to their operation unless specifically stated otherwise by the corresponding API documentation; those events are only raised by their respective user interaction.
