SparklineEdit() Constructor

In This Article

Initializes a new instance of the SparklineEdit class with default settings.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v24.2.dll

NuGet Package: DevExpress.Win.Navigation

#Declaration

public SparklineEdit()

#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.

using System;
using System.Drawing;
using System.Windows.Forms;
using DevExpress.Sparkline;
using DevExpress.XtraEditors;

private SparklineEdit CreateSparkline() {
    // Create a Sparkline editor and set its dock style.
    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 markers.
    view.HighlightStartPoint = true;
    view.HighlightEndPoint = true;
    view.HighlightMaxPoint = true;
    view.HighlightMinPoint = true;
    view.HighlightNegativePoints = true;
    view.SetSizeForAllMarkers(10);

    return sparkline;
}

private double[] CreateData() {
    return new double[] { 2, 4, 5, 1, -1, -2, -1, 2, 4, 5, 6, 3, 5, 4, 8, -1, 6 };
}
