Hai Peter,

If i give the chart control large data of about 30000 double values suppose,It will definitely
take some time to render.Before I supply next set of data of same size ,is there any way to check the graph rendering has been completed or not.

Regards

Hi Amal,

When you finish running the charting code, the rendering is completed.

If you can check whether rendering is completed, that means your code is multi-threaded (that is, when ChartDirector is using the thread for rendering, part of your code is still running in another thread). You can check if the rendering thread has been completed to see if the chart rendering has been completed.

An example is like:


hasCompleted = false;

..... create the chart and set it to the chart viewer

hasCompleted = true;

Your code in another thread can then check the hasCompleted variable to see if rendering has been completed.

Hope this can help.
