Re: Slow plotting on last plot

Randy,

I previously used the draw now command and yes, it does update, but I
still get the 100% CPU usage. I don't quite understand it. I'm
guessing its a windows/MATLAB problem, but don't know what it is. I
might just uninstall and try reinstalling.

I've noticed that on my computer the last plot generated takes
forever to update. My system hangs with 100% CPU usage for
almost
a
minute before the final plot is generated. It isn't specific to
any
single plot. If I add a plot after the loop, then that
additional
plot takes the time to generate instead of the previous one.

I'm using R2006a.

Has anyone else noticed this behaviour or how to fix it? I'm
open
to
suggestions.

Perhaps it has something to do with the queuing of graphics
commands. Often graphics updates are not performed
immediately but queued up and then performed in a block
later, during an idle interval.

Try putting "drawnow;" inside the loop after each plot
command.

HELP DRAWNOW for more info.

The fact that it takes nearly a minute to execute all the
graphics suggests you have a very complex plot. If so, you
might find with DRAWNOW that the overall time is still
the same, but each iteration now takes a significant fraction
of a second.
