Other noteworthy plot commands
==============================

While you saw several plot command and know how to do
different 2D and 3D plots, we will list here some other
plot command that might be interesting.

Plots in the complex plane
--------------------------

Plots of a possibly complex function in the complex plane
can be easily done with plot routines from the ``mpmath`` python
package.

The example plots the gamma function over the complex plane::

   import mpmath as mp

   mp.cplot(mp.gamma, re=[-4,4], im=[-4,4], points=10000, file="gamma.png")

This is all for plotting the gamma function in the
rectangle -4 < Re(z) < 4 and -4 < Im(z) < 4. The
above call saves the result to the file "gamma.png"
which looks like this:

.. image:: images/gamma.png
   :scale: 100 %
