    Hi All,

    I would be working in a web application project wherein am going to make extensive usage of chart control provided by RadGrid.
    I happened to look through most of the demonstrations provided by Telerik for the ASP.Net Ajax Chart control.

    I would like to know whether the chart control supports moving (or) dragging of points in a line chart which would trigger a change in the position of the vertices.

    The dragging event could either be a server side or a client side event. However, only specific points should be draggable depending upon some set of criterias.

    Also, the datasource for the line chart is expected to be dynamic. Is it possible to achieve such a functionality using the chart control? Any insights?

    Hi Raghu,

    Currently we don't support such type of interaction with RadChart. However if you provide us more information together with images of how would you like your axes to change based on the drag/drop maybe we will be able to help you more properly.

    Best wishes,

    Hi Evgenia,

    Thank you very much for reverting back.

    Please refer to the snapshot of the chart control in action that I have attached.

    Now let us consider an arbitrary point in that snapshot say '100000' which lies in the month of 'May'. I would wish to change the value from 100000 to 40000 by dragging the point so that the graph budges accordingly.

    Here, let us define a criteria where only the points lying from May to December should be draggable.
    i.e. Whenever the user attempts to drag a point lying between the month range of January-April, nothing should happen.

    Is it possible to achieve such functionality using RadChart? Awaiting your inputs on this at the earliest.

    Thanks & Regards,

    Hello Raghu,

    RadChart is just an image rendered on the server and sent to the client. This means that unfortunately there is no practical way to drag and drop elements of it.
