C#

[DefaultValue(false)]
public bool EnableAxisXScrolling { get; set; }

VB.NET

<DefaultValue(False)>
Public Property EnableAxisXScrolling As Boolean

Property Value

Type	Default	Description
Boolean	false	true if the heatmap can be scrolled horizontally (along an x-axis); otherwise, false.

Remarks

The following properties allow you to enable navigation in the Heatmap Control:

• EnableAxisXScrolling
• EnableAxisYScrolling
• EnableAxisXZooming
• EnableAxisYZooming

To check whether zoom or scroll operations are available, use the IsScrollingEnabled and IsZoomingEnabled properties.

Use the methods below to zoom and scroll a heatmap programmatically:

• ZoomIn()
• ZoomOut()
• Scroll(HeatmapHorizontalScrollingDirection, HeatmapVerticalScrollingDirection)

Call the HeatmapControl.ResetZoom() method to reset the current zoom state to the default value.

Example

The following code enables zoom and scroll operations in a heatmap:

C#

using DevExpress.XtraCharts.Heatmap;

namespace HeatmapChart {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();

            HeatmapControl heatmap = new HeatmapControl();
            this.Controls.Add(heatmap);
            //...
            heatmap.EnableAxisXScrolling = true;
            heatmap.EnableAxisYScrolling = true;
            heatmap.EnableAxisXZooming = true;
            heatmap.EnableAxisYZooming = true;
        }
    }
}

VB.NET

Imports DevExpress.XtraCharts.Heatmap

Namespace HeatmapChart
    Public Partial Class Form1
        Inherits Form

        Public Sub New()
            InitializeComponent()
            Dim heatmap As HeatmapControl = New HeatmapControl()
            Me.Controls.Add(heatmap)
            '...
            heatmap.EnableAxisXScrolling = True
            heatmap.EnableAxisYScrolling = True
            heatmap.EnableAxisXZooming = True
            heatmap.EnableAxisYZooming = True
        End Sub
