CartesianCustomLineAnnotation along with text annotation

[Bipin]

Hi
We are working on CartesianCustomLineAnnotation and we want display intersection of custom line annotation with
ScatterLineSeries. Right now we are able to find out the intersection point which we are displaying at top right corner.

PFA. Please let us know how to resolve this issue?

Thanks

Hi Bipin,

There are two ways that you can solve this, depending on the specifics of your scenario:

• If you need to display vertical or horizontal lines (not sloping) you can use GridLine Annotations which have built in support for labels. Here's an example:

  <telerik:CartesianGridLineAnnotation
             Axis="{Binding HorizontalAxis, ElementName=chart}"
   Value="{Binding XValue}"
   Label="{Binding XValue}">
      <telerik:CartesianGridLineAnnotation.LabelDefinition>
          <telerik:ChartAnnotationLabelDefinition Location="Right"
                                  VerticalAlignment="Top"/>
      </telerik:CartesianGridLineAnnotation.LabelDefinition>
  </telerik:CartesianGridLineAnnotation>

• If the lines can be sloped than you will need to display the text using CartesianCustomAnnotation, in addition to using CartesianCustomLineAnnotation.

I hope this helps.
