Zooming and Scrolling

The chart control allows you to zoom and scroll charts. This makes it easy to see data points in a chart that has thousands of points. To zoom, simply make sure the chart has focus and then use the mouse wheel.

// Sample Code
    Dim Diagram As ChartDiagram2D
    Set Diagram = ChartControl.Content.Diagrams(0)
    Diagram.AllowScroll = True
    Diagram.AllowZoom = True
    Diagram.AxisX.Range.ViewAutoRange = False
    Diagram.AxisX.Range.ViewMaxValue = 200
    Diagram.AxisX.Range.SideMargins = False
