Public ReadOnly Property WholeRange As WholeRange
| Type | Description |
|---|---|
| WholeRange |
A WholeRange object representing the settings for the whole range of an axis.
|
Use the WholeRange property to define the whole range in which scrolling is allowed for an axis, when scrolling is enabled (the XYDiagram2D.EnableAxisXScrolling or XYDiagram2D.EnableAxisYScrolling property is set to true ) and the automatic axis range detection is switched off (the Range.Auto property is set to false ).
Then, you can set the Range.Auto property to false , and manually define the Range.MaxValue and Range.MinValue properties to determine the axis values through which the diagram can be scrolled. You can also obtain Range.MaxValueInternal and Range.MinValueInternal properties.
In addition, you can use the Range.AutoSideMargins property to force 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).
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.
For more information on axis range, refer to Visual Ranges and Whole Ranges.
