Example

This example demonstrates how to create a sparkline control, fill it with data, choose the way to represent this data, and customize the sparkline appearance.

To do this, you should create a SparklineEdit object and assign the datasource object to its BaseEdit.EditValue property. Then, you need to set the appropriate view instance to the SparklineEdit.Properties.View property and customize view properties to meet your requirements.

Note that in this sample, the AreaSparklineView class is used to display area sparklines. To display other sparklines types, use the BarSparklineView, LineSparklineView or WinLossSparklineView classes instead.

    // Create an Area view and assign it to the sparkline.
