BI Dashboard for WinForms - Custom Trend Indicator

The following example creates a custom WinForms “Moving Average” indicator (when using DevExpress BI Dashboard):

1. Create a ChartCustomIndicator descendant (the MovingIndicator class in this example). MovingIndicator accepts a collection of data points, evaluates values, and returns resulting points. These points are used to draw the indicator.

2. Register MovingIndicator in IndicatorFactory to make it available as an indicator type within the Trend Indicators editor. Call the Register method in your application before you save and load a dashboard (to serialize and deserialize the indicator within the dashboard’s XML).

3. Create an instance of MovingIndicator and specify desired indicator settings.

4. Add MovingIndicator to the chart indicators collection to display the configured indicator within DevExpress Dashboard’s UI.
