Generate chart image without displaying the chart

[Brett Robichaud]

I'm using RadChart v2011.3.11.1219 with a .Net 4.0 WinForms app using VS 2010 sp1. In this app I am displaying a couple of charts, but I am wondering if it is possible to generate a line chart and save it to png without ever displaying the chart?

How would I go about doing that?

Hi Brett,

Here is a small example:

public MyForm()
        {
            InitializeComponent();

            RadChart chart = new RadChart();
            chart.DefaultType = Telerik.Charting.ChartSeriesType.Line;
            chart.DataSource = new double[] {2,3,4,3,4,3,4,5};
            chart.DataBind();

            chart.Save("C:\\mychart.png");
        }

RadChart is never added to the form, but it is only used to generate the output image. You can find a more complex example of creating RadChart in code here. Once you have it configured and populated, you can call the Save method to export the chart to an image.

Doh! That is about as simple as it gets. Thank you Ves!

Hi, 

Is there a way to do this with the new RadHtmlChart for Asp.Net ?

Or should I use the "obsolete" RadChart if I want to generate the image without displaying the chart ?

Hello Christophe,

concerns UI for WinForms. Please address your question in the ASP.NET AJAX forums to get proper advice: http://www.telerik.com/forums/aspnet-ajax
