Thanks for the response, Actually Object meaning a new graph here I drag a new graph on existing canvas with huge data. In my case I have near 20 graphs to plot on a same canvas each having 50k + points it means at last it will have 20 graphs on single canvas.

But now, When I drop nearly 12 graphs on a canvas it leads refreshing a browser(Internet Explorer recommended).

For every drop I get data from server and need to push into existing data holder. and then it re renders all the graphs. For this problem I asked for the alternate way, but if you have any solution for the same please let me know.

Thanks.
