Property Value

Type Description
ScrollingRange

A ScrollingRange object representing the scrolling range settings of an axis.

Remarks

Use the ScrollingRange property to define the range in which scrolling is allowed for an axis, when its scrolling is enabled (the XYDiagram2D.EnableAxisXScrolling or XYDiagram2D.EnableAxisYScrolling property is set to true) and the automatic axis range detection is switched off (the AxisRange.Auto property is set to false).

Then, you can set the ScrollingRange.Auto property to false, and manually define the ScrollingRange.MaxValue and ScrollingRange.MinValue (or ScrollingRange.MaxValueInternal and ScrollingRange.MinValueInternal) properties, to determine the axis values through which the diagram can be scrolled.

In addition, you can use the ScrollingRange.SideMarginsEnabled property, for an axis to automatically extend its range so that indents are preserved on the both ends of the axis.

For more information, refer to Visual Ranges and Whole Ranges and Zooming and Scrolling (2D XY-Charts).

Examples

This example demonstrates how to use the AxisBase.VisualRange property to define the visible range of an axis, and the AxisBase.WholeRange property to define its whole range.
