BarSeries Linear Axis

[Charlie]

How can I display a BarSeries with a linear axis on the horizontal?

My application needs to display columns along an x axis that is fixed from 0 to 100.

Hello Charlie,

You can use a scatter point series with a point template that looks exactly like a Bar Series, i.e. having a Linear Horizontal Axis.
 For the purpose you can render the scatter points as lines originating from the X axis with Width set per your own scenario needs:

<telerik:ScatterPointSeries.PointTemplate>

             <DataTemplate>

                        <Canvas Width="2" Height="2">

                            <Rectangle Width="2" Height="2000" Fill="Blue"/>

                        </Canvas>

             </DataTemplate>

</telerik:ScatterPointSeries.PointTemplate>

Let me know how this works for you and whether you need any further assistance.

Thank you, this works as needed.

This solution combined with ClipToPlotArea="False" produces lines that stretch beyond one of the axis. Is there a way to set height dynamically so lines only until axis? I tried YValue binding but the lines were shorter then they should be.

Hello Andrew,

A possible approach to resolve this is to use an IValueConverter to calculate a Height for the Rectangle in the PointTemplate. I've prepared a small example showing this approach. Can you please give it a try and let me know how it goes?

Thanks! This example works when window is a fixed size. Is there a way to add a binding to point template to update it based on chart size?

Hi Andrew,

To achieve your requirement also on size changed of the chart, you can use a bit different approach. I've shown this in the attached project. I hope it helps.
