Thanks Tamas,
This seems to be very easy to use, but I have trouble with the graphics software:
On my Linux desktop when I run 'plot' the script freezes -after a few seconds the CPUs go idle, no output goes to the terminal, no windows open, when I ctrl-c out I also get no information on what the script was doing, it just terminates.
I also tried on my OSX laptop, but here I ran into trouble with installing the pycario graphics library interface. I download the source code but './configure' fails with the error: configure: error: cannot find install-sh, install.sh, or shtool in "." "./.." "./../.."
I have tried googling for the solution, installed a few suggested libraries with brew but had no success.
Any ideas on how to proceed on either of the systems?
