BarSparklineViewBase Class

The base for Bar and WinLoss sparkline views.

Namespace: DevExpress.Sparkline

Assembly: DevExpress.Sparkline.v19.2.Core.dll

Declaration

public abstract class BarSparklineViewBase :
    SparklineViewBase
Public MustInherit Class BarSparklineViewBase
    Inherits SparklineViewBase

Remarks

In addition to the API implemented by the base SparklineViewBase class, the BarSparklineViewBase class also introduces the BarSparklineViewBase.BarDistance property, which specifies the distance between two bars in either the BarSparklineView or WinLossSparklineView.

Examples

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.

            SparklineEdit sparkline = new SparklineEdit();
            sparkline.Dock = DockStyle.Fill;

            sparkline.EditValue = CreateData();

            // Create an Area view and assign it to the sparkline.
            AreaSparklineView view = new AreaSparklineView();
            sparkline.Properties.View = view;

            // Customize area appearance.
            view.Color = Color.Aqua;
            view.AreaOpacity = 50;

            // Show markerks.
