How to hide a line segment from rendering?
Using the extensible feature set of WPF, Essential Chart allows you to customize the segments rendering as desired. If you want to make an empty point in the desired Y value or to make a difference in a point, use template for the ChartSeries, which will render gaps for the specified empty points.
<DataTemplate x:Key="Template1"> <Line Name="Line1" X1="{Binding X1}" X2="{Binding X2}" Y1="{Binding Y1}" Y2="{Binding Y2}" StrokeThickness="2" Stroke="{Binding Interior}" /> <DataTemplate.Triggers> <DataTrigger Binding="{Binding Path=CorrespondingPoints[0].DataPoint.Y}" Value="6" > <Setter Property="Stroke" Value="Transparent" TargetName="Line1" /> </DataTrigger> <DataTrigger Binding="{Binding Path=CorrespondingPoints[1].DataPoint.Y}" Value="6" > <Setter Property="Stroke" Value="Transparent" TargetName="Line1" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate>
Refer to the attached sample which illustrates this feature.
