replot() with big dataReturn to overview

My system has 800 Mhz processor and 256 MB memory and my plot has 2000 x-values. The replot() function takes appr. 1000 ms and it is slow for me because my system freezes if replot() is called in series. What do you suggest me to overcome this problem.

So are you trying to draw a real-time plot? Is this right?

yes. Also I gives some information about x-value which selected by user. In each selection, I called replot().

I have a similar problem: I'm trying to replot the graph when a mouse move event is generated... but also in my case the system freezes...

I found this
if you hide grid, replot() speed up.
