Property Value

Type Description

The text that the chart legend uses as a constant line’s display name.


Use the LegendText property to specify the text that will identify the current constant line in a legend.

A chart legend does not show constant lines by default. To include a constant line description in a legend, set the ConstantLineBase.VisibleInLegend to true.


This example shows how to add a constant line to a numeric y-axis, customize its appearance and show it in the chart legend. To do this, add a NumericConstantLine object with the specified properties to the NumericAxisY.ConstantLines collection.

NumericAxisY Constant Line


              <dxc:NumericConstantLine AxisValue="{Binding ViewModel.NightTempAverage}"
                                       LegendText="Average Annual">
                  <!-- Customize the constant line title. -->
                      <dxc:ConstantLineTitle Text="{Binding ViewModel.NightTempAverage, StringFormat='{0}°C'}"
                                      <dxc:TextStyle Color="#7f43bf" Size="12"/>
                  <!-- Customize the constant line appearance. -->
                      <dxc:ConstantLineStyle Stroke="#7f43bf" Thickness="2" Dashes="7 3"/>
