I have attached a simple app where all I am doing is adding points to chart and removing them. But when I open the task manager and look at delta memory if iExlorer, It keep on increasing. Any help?
Just to accelerate the leak set the process afinity in task manager to run on one cpu and then you will the the chart goes slower and slower and slower and finally dies.
I believe you are running into a memory leak that we fixed recently with respect to the x axis labels. The fix should be in the next service release. See this thread for more details:

I can replicate your problem on the service release binaries, but the problem has since been resolved, so should be available in the next release/service release. In the interim, you could see if the linked workarounds mitigate the issue.
Hope this helps!
