    Hi guys,

    Disclaimer: I'm new to the Telerik forums but I have done my due dilligence and gone through the RadChart tutorials and Help files. Still this seems like something obvious so I appologise if I just haven't seen the setting.

    My question is how do I get Scrolling and Zooming working on WinForms RadChart like it does on the ASP.NET AJAX RadChart (http://www.telerik.com/help/aspnet-ajax/featureszoomscroll.html)

    From reading the forums it appears that this is not possible specifically the threads:

    If it is not possible then is there some code I can use to get this working? I would like to display a semi transparent region between the user's mouse down and current mouse position. Then after the mouse up event I would like the graph to be zoomed to the selected region.

    I tried implementing this but ran into the following problems:

    1. OnMouseDown = I couldn't figure out how to translate the current mouse (X,Y) position into the current point on the PlotArea (i.e. you clicked on X Axis = 50, Y Axis = 1000).
    2. I could not figure out how to draw a transparent (dynamically resized) rectangle over the top of my graph elements. I looked at using CustomFigures but couldn't figure out how to dynamically change the points.

    Any help would be greatly appreciated.

    Hello Walter,

    I confirm that Zooming and scrolling is currently not available in RadChart for WinForms. There is, however, a KB article demonstrating a way to implement such behavior on your own. Please, take a look at

    You can find more information and resources at http://www.telerik.com/products/winforms/resources.aspx

    Should you have further questions, do not hesitate to write us back.

    Best regards,
