Visualizing data is critical to understanding the data.  What does
a function, :math:`f(x)`, do when :math:`x` is near zero or very large? Are
there any discontinuities? Where does :math:`f(x)` cross the :math:`x`--axis?
If the data is statistical in nature, are there any outliers? Do we know enough
about our data to make data--driven decisions?  We need to 
make effective two and three-dimensional data plots so that we and 
others can understand the data.

We made several simple plots in :ref:`matlab` for the purpose of learning about
the features of |M|. Here we direct our attention specifically to plotting.
Keep in mind that |M| has a large variety of plotting options, so we can
only cover the essentials of plotting.
