Thanks your suggestion solved my problem.

Hi,

The chart will overwrite the last generated image - the server will simply pick the last generated image if it does not use caching.

When chart is rendering the other users that are opening that page will have racing condition or not? Or will the webbrowser will just show the last image.

BTW, chart will be overwrite without problem or it has to be removed first?

Hi JSW,

In that case you can use the control to generate a store an image on the server like:

using (NChartControl chartControl = new NChartControl())

{

// configure control here

// render to image

chartControl.ImageExporter.SaveToFile("c:\\temp\\chart.png", new NSize(400, 400), NResolution.ScreenResolution, new NPngImageFormat());

}

That will generate a static image on the server that you can then reference in the HTML.

Hi
I observed that if i set a webpage to server cache the chart url no longer there so it show as white blank.
How to fix such situation? The chart calculation can be intensive so i do want to cache result no to call sql everytime.
