BI Dashboard for ASP.NET Core - Custom Trend Indicator

The following example creates a custom ASP.NET Core “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. 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. Register ChartIndicatorsExtension before the control is rendered to add the MovingIndicator type to the Trend Indicators editor.

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

5. Once you launch the application, open the Trend Indicators editor and add the new "Moving Average" indicator type.
