    Hi,

    I'm using the Trial version of Telerik for development of a web App and decided to buy it. I see in the details of the purchase there is the source code of the controls and I want to know to what extent I will be able to modify the Chart component.

    What I need in my application is to generate a chart with interpolated values, and every time the chart is zoomed the data need to be re-interpolated. This is something I couldn't achieve with RadChart.

    The question is, there is a way to achieve this functionality modifying the source code of the RadChart by myself or the way it's implemented don't allow this.

    Thanks in advance,

    Simón de Lizarza

    Hi Simón,

    Technical support does not cover modifications of the control source code. That means you are free to modify it as you want, however, we will not be able to provide assistance for the modified product.

    That said RadChart does not offer interpolation. By that I mean it will not combine 10 data points into 1 or vice versa. You will have to generate your series items manually. That doesn't require changing the source code of the control.

    I hope this clears things a bit.

    Ok, so, there is a way to redraw the series when the user zoom in or out the chart?  Using the information of the region zoomed (limits of X and Y) I'll need to re-generate the series with new interpolated values and redraw the chart. Those new values need to be processed by a procedure on the server side after the action of zoom. This is something I didn't managed to achieve using the server events provided by RadChart. So, my question is, do you think there is a way to modify the source code of RadChart to achieve this functionality?

    Thanks,

    Hello Simón,

    Generally speaking RadChart interpolates the points based on the initial Series you provided. If you wish to provide more detailed data you should rebind the chart when zooming.
