hi
i am using Syncfusion chart control for showing graph of live data . What we did is ,if user download the data for the graph of particular item and close the graph.
And then it again opens the graph with same item , then our graph first plot the chart with the downloaded file and after that it takes the fresh values.
problem is that if the size of file increase means the data in Downloaded file is more then our graph start taking memory(means first if it will takes 60-70 Mb of memory tehn at this point it starts taking above 220 MB of memory)
but this problem comes when at the same time fresh data is coming for that item from server.

Pl'z suggest me some solution for this problem.

Thanks in Advance
Gourav

Hi Gourav,

Thank you for the update.

On further investigation, we found that the issue "Memory Usage keeps increasing while refreshing the chart with new data’s" is not a bug. It is normal behavior of garbage collector. Garbage collector uses some "lazy" methods of free memory.

Please refer the below article to get more details regarding Garbage Collection:

Kindly let me know if you have any other questions.

Thanks,
