WinLossSparklineView Class

The WinLoss sparkline view.

Namespace: DevExpress.Sparkline

Assembly: DevExpress.Sparkline.v19.1.Core.dll

Declaration

C#

public class WinLossSparklineView :
    BarSparklineViewBase,
    IBarSparklineInfo,
    ISparklineInfo

VB.NET

Public Class WinLossSparklineView
    Inherits BarSparklineViewBase
    Implements IBarSparklineInfo,
               ISparklineInfo

Remarks

The sparkline type is defined by the SparklineEdit.Properties.View property, which can contain of the following SparklineViewBase class descendants:

• Area (AreaSparklineView)
• Line (LineSparklineView)
• Bar (BarSparklineView)
• Win/Loss (WinLossSparklineView)

Below is an example of a grid control with Line sparklines displayed in its second column.

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.
