Property Value

Type	Description
Object	An Object that specifies the axis value to which the custom label corresponds.

Remarks

The Value property specifies the position of a custom label along the axis to which it belongs. The value set for the Value property should fall in the range specified by the Axis.Range property, and be defined in measurement units appropriate for the axis scale type.

Example

This example demonstrates how custom axis labels are created and customized in the Chart control.

To add a custom axis label on the chart, create a CustomAxisLabel object and add it to the CustomAxisLabelCollection returned by the Axis2D.CustomLabels property.

To show the custom label on the X-axis or Y-axis, specify an axis value that corresponds to the label position on an axis (using the CustomAxisLabel.Value property) and to its content (via the CustomAxisLabel.Content property).

You can customize custom label appearance using the Foreground, FontFamily, FontWeight, and FontStyle properties for the AxisLabel object.

For more information about custom axis labels, see the Axis Labels topic.
