is't possible show a custom line on chart?

[Anders]

I want show a custom line (target line) on the chart 

like the picture attached.

to be shown a red grid line,and show a target value at left 

and I have found a similar sample for silverlight here
http://www.telerik.com/help/silverlight/radchart-features-annotations-custom-gridline.html

but I didnt found this feature in ASP.NET AJAX.

is possible do something like this ?

thanks

Hello Anders,

Unfortunately this would not be possible in the ASP.NET version of the control. Generally in some scenarios it is possible to use really thin MarkedZone to simulate the behavior of custom gridline, however this is applicable mostly to scenarios with Line series type (the problem with Bar series type is that the marked zone is actually rendered under the series, and the bar items would overlap it).


All the best,

Thanks admin

 I'm using MarkedZone, show a thin gridLine without tip text and need to calculate the height (ValueStartY ,ValueEndY)

see the picture attached.

anyway, that's good also. thanks!
