Range.MaxValue Property
Gets or sets the maximum value to display on an Axis. This may not be the same as the maximum value of the series associated with this axis.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v19.1.dll
Declaration
[XtraSerializableProperty(XtraSerializationVisibility.Hidden)]
public object MaxValue { get; set; }Property Value
| Type | Description |
|---|---|
| Object | A Object that specifies the maximum value to display on an axis. |
Remarks
Use the MaxValue property to specify or obtain the maximum value to display on an axis.
Note that the MaxValue and Range.Auto properties are interdependent: changing one property will reset the other.
Note
Dealing with Qualitative or DateTime scale types, it may be required to determine the maximum value more precisely than allowed by these scale types. For example, for an axis whose DateTimeScaleOptions.MeasureUnit property is set to Year, it may be required to restrict its range by Month. To do this, you can use the Range.MaxValueInternal property, which stores the internal, numeric representation of Qualitative and DateTime values.
For more information, refer to Visual Ranges and Whole Ranges.
Example
The following example demonstrates how to create a ChartControl with a series of the RangeAreaSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.
Then, add the following code to the Form.Load event handler.

// Create a new chart.

// Create a range area series.

// Add points to them.
