I am planning to use telerik on some scientific application where we plot a lot of data, and since there is huge amount of data the plot will be a "summary" and "detail" chart where the summary plot will have a summarized value for, say, each minute over a longer period of time and a detail plot will lot the value of each minute's worth of data when the user selects that particular minute.

Now, I am planning (or at least the requirement says) that the summary plot have a movable ( and i am not sure if this is the correct term but) vertical cursor, which can be dragged by the user from one point to point and this event is to trigger the details plot for the corresponding point the user rests at.

I have attached a portion of a screen capture of the summary plot. The orange line in the picture is to be the cursor.

Does anyone have any idea how to do this in telerik charts for WPF? Does anyone know if it is possible?

Thanks a bunch..

Hi Dawit Alemu,

We are currently in the process of implementing zooming & scrolling functionality in RadChart similar to the one found in our ASP.NET Control. It is currently working with very large data sets (100,000+) with decent performance.

Thanks for your prompt reply.

Can you suggest any work around in the mean time that can help me with this? are the data points in radchart control click-able? Can I wire events to the data points to drive a secondary data plot with this event?

Any help would be appreciated. 
thanks

I will add some to the question that I asked above, if I may. Is there a way to draw lines and shapes on top of a 2D chart (line chart), say arrows vertical lines, horizontal lines ? I want to tie this to the item clicked event of the chart then drive a secondary chart plot based on the point that is clicked.

Any hints of even where to start reading about this will be greatly appreciated.

thanks.

Hi Dawit Alemu,

You can consider this example. It shoulds how to handle click events and rebind the chart achieving a drill-down scenario. Also, you can use LineSeries to simulate drawing lines on the chart canvas. Hope that helps.

Hi, all

This is definitely a feature worth having.  Understandably, we can visualize the information using drilldowns (as in the example), but is a chart 'cursor' feature on the roadmap of WPF controls?

thanks in advance.

Hi everyone,

Yes, we are working on marked zones and annotations (part of which is vertical the line described), but we will not be introducing it before Q3 2010.

Best,
