Here are some useful examples/templates scripts for ploting with MatPlotLib/NumPy. They have many options to change : domain, function, labels, title, etc. To adapt them to your use, just open the .py file with a text editor (for example Nano for Nokia N9 in Nokia Store), change the definitions in the section "# Personalize your plot parameters here", save and run (using Terminal) :
$ python <scriptname>.py
Timings for MatPlotLib 1.2.0 and NumPy 1.4.1 on Nokia N9.

plotfx.py : Plot of one variable, f=f(x), saving to a (PNG) file. Takes 8.4 s on Nokia N9.


contourfxy.py : contour plot of two variables, f=f(x,y), saving to a (PNG) file. Takes 10.2 s on Nokia N9.


densityfxy.py : density shaded relief plot of two variables, f=f(x,y), saving to a (PNG) file. Takes 10.3 s on Nokia N9.


vectorfieldFxy.py : vector field plot in 2D, F=F(x,y), saving to a (PNG) file. Takes 8.2 s on Nokia N9.


surfacefxy.py : surface plot of two variables, f=f(x,y), saving to a (PNG) file. Takes 16.6 s on Nokia N9.
