Hi,

I have to plot some rectangles in for example a RadCartesianChart.

I have tried to do it with the AreaSeries but when i do so all rectangle are bound to the x axis.

I want to be able to plot Rectangles anywhere within the RadCartesianChart(see attached image).

I hope you understand the problem :)

Can i do this using the AreaSeries or should i do something else?

Best Regards,
Jeppe

Hi Jeppe,

I think that I understand your requirement and I am happy to inform you that there is straightforward way to achieve it. The RadChartView control supports annotations. I think this feature perfectly fits your custom scenario. Please take a look at our documentation and let us know if you need any further assistance.

Hi Pavel,

Thanks for the reply, this looks great! My data is so that i have 4 datapoints, each with an x and y coordinate.
These 4 datapoints creates the rectangle.
I think that the CartesianMarkedZoneAnnotation would be the best solution in my case.
Do you agree?

Best regards,
Jeppe

Hi Pavel,

I have been having some trouble understanding the marked zone. I have tried the following:
<telerik:RadCartesianChart x:Name="chart">
    <telerik:RadCartesianChart.VerticalAxis>
        <telerik:LinearAxis/>
    </telerik:RadCartesianChart.VerticalAxis>
 
    <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:CategoricalAxis IsInverse="True"/>
        </telerik:RadCartesianChart.HorizontalAxis>
 
    <telerik:RadCartesianChart.Annotations>
        <telerik:CartesianMarkedZoneAnnotation HorizontalTo="2.75"
                               VerticalFrom="0.5" VerticalTo="1"/>
    </telerik:RadCartesianChart.Annotations>
</telerik:RadCartesianChart>

Shouldnt the above code plot the same marked zone annotation as on the image(taken from telerik homepage) i have attached?
I must have misunderstood how to use these markedzones.

Best regards,
Jeppe
