Details:

I have a file called Convergentfield which I have attached. In it I use
scatter3 to plot points. Without setting plot point colours, I am able to plot
thousands of points without issue, however using a colour map crashes the
program with 'panic: Segmentation violation' when the number of points
increases beyond some cutoff, for myself I have narrowed this cutoff to lie
somewhere between 500 and 600 points (saved in the variable 'n' in the
script).

I experienced the crash first via command line, however I also get a crash
when running the script through the GUI (though without an error message).
Interestingly, when I had a large number of points, and ran from the GUI, the
plot window opens, and occasionally updates the plots in the frame, seemingly
correctly, and then after finishing the process, closes the plot window and
the GUI completely.

I am on Winodws 8 which apparently can have some problems with the GUI, hence
why I was working from command line to start with. Perhaps that is part of the
problem. I would be interested to know the results others have with the
script.
