Hello scorp,

Dynamic Marked Zones on the Chart is not currently possible. However your feedback was sent to our developers and they will decide whether and when this will be made in future.

Is there are alternative. Can we have a StackedArea100 chart without the point marks visible on the chart along with the line chart.
Can I get an example if so on how to achieve this.

Hello scorp,

You can use our 2D Stacked Area100 Chart as MarkedZone with turning off the Visibility of it's SeriesItemsLabels and PointMarks. You may follow our demo with full source code to achieve this.

However have in mind that the StackedArea100 Chart type should be added first so that it stands as Background to other Series (otherwise it will cover the Series you've added first as Chart is laying the Series one over another keeping the order by which they were created).

How can I have the last datapoint not truncated from the chart. Take a look at the image below to see what I am talking about.

I tried to put the AxisX.LayoutMode = AxisLayoutMode.Inside and the result is this:

Can you suggest something better. The line series acting as marked zones should ideally start from the left most of the chart all the way to the right.

Thanks.

Hello scorp,

The issue you are facing is caused by the fact that the last datapoint of the Line Series (which you are using as MarkedZones) is on the same XValue as the green DataPoint you have on your Chart Area.
That's why no matter if you set the LayoutMode of the YAxis to Inside or Between the Line Series will always be cutted from left and right.
What I can suggest is that you set the Start XValue for the first PointMark of each Line Serie to 2006 and the end XValue to 2011 (currently they are 2007 and 2010). Then set the XAxis to start from 2007(MinValue) and end in 2010(MaxValue) with turning off the AutoRange property as described in our help topic.

Kind regards,

That worked out pretty good. http://img685.imageshack.us/img685/8223/95806532.jpg
Now I need to make it look like : http://img816.imageshack.us/img816/6448/39614802.jpg
I was hoping to use the StackedArea100Series however from the demo you had suggested the viewmodel file is missing.

Hello scorp,

You can find the full source code for our examples under your installation path - for example - C:\Program Files\Telerik\RadControls for Silverlight Q1 2011\Demos.
