Why do I get a General Protection fault error when I plot data with PlotPoint?

[impuls]

When I try to plot data from an array with PlotPoint() I sometimes get a general protection fault. The problem occurs randomly. It is not that the array contains a lot of points: about 50.
I'm programming in CVI 6.0 under Windows XP.

Hello,
Just out of curiousity, is there any particular reason you don't want to use PlotXY function, instead of calling PlotPoint in a loop that iterates the array 50 times?

Any way, as for the errors, are you interacting with any kind of hardware (e.g. DAQ or instrument control) while plotting on a graph?

I allready changed PlotPoint() to PlotXY() and now I don't have any more troubles.

I'm not interacting with any hardware while plotting. On that moment plotting is the only activity my application has to perform. So I still don't see why it goes wrong... but I'm happy that there was a way around it.

thanks
