C#

using DevExpress.XtraCharts;
using System;
using System.Windows.Forms;
// . . .
private void OnFormLoad(object sender, EventArgs e) {
    XYDiagram xyDiagram = chartControl1.Diagram as XYDiagram;

    // Enable scrolling and zooming for both axes.
    xyDiagram.EnableAxisXZooming = true;
    xyDiagram.EnableAxisYZooming = true;
    xyDiagram.EnableAxisXScrolling = true;
    xyDiagram.EnableAxisYScrolling = true;

    // Click the left mouse button while the Shift key pressed to zoom in to the diagram.
    xyDiagram.ZoomingOptions.ZoomInMouseAction.ModifierKeys = ChartModifierKeys.Shift;
    xyDiagram.ZoomingOptions.ZoomInMouseAction.MouseButton = MouseButtons.Left;

    // Click the left mouse button while the Ctrl key pressed to zoom out of the diagram.
    xyDiagram.ZoomingOptions.ZoomOutMouseAction.ModifierKeys = ChartModifierKeys.Control;
    xyDiagram.ZoomingOptions.ZoomOutMouseAction.MouseButton = MouseButtons.Left;

    // Press Alt + M to zoom in to the diagram.
    xyDiagram.ZoomingOptions.ZoomInShortcuts.Add(Keys.Alt | Keys.M);
