Draw annotations behind the lineseries

[Wouter]

Is it possible to draw annotations behind lineseries? We use CartesianPlotBandAnnotation to draw regions on our grid, but it needs a semitransparent Fill, otherwise the lineseries are hidden. This deteriorates the color chosen for these regions. Is there a way to draw the annotations behind the graph?

Thanks,
Wouter

Hi Wouter,

I think you should only have to set the ZIndex property of the annotation to about -250. Note that this is not the Panel.ZIndex property, but a property of the annotation.

Thanks this works nicely. The annotations are drawn behind everything including the striplines of the grid. This was solved as follows:

<telerik:RadCartesianChart.Grid>
  <telerik:CartesianChartGrid StripLinesVisibility="Y" MajorLinesVisibility="None">
    <telerik:CartesianChartGrid.YStripeBrushes>
      <SolidColorBrush Color="#33999999"/>
      <SolidColorBrush Color="Transparent"/>
    </telerik:CartesianChartGrid.YStripeBrushes>
  </telerik:CartesianChartGrid>
</telerik:RadCartesianChart.Grid>

Hi Wouter,

I suggest you play with the ZIndex to find a proper value that will position the annotation below the series and on top of the grid, instead of using the transparency trick.
