<p>The rcsetup module contains the default values and the validation code for
customization using matplotlib’s rc settings.</p>
<p>Each rc setting is assigned a default value and a function used to validate
any attempted changes to that setting. The default values and validation
functions are defined in the rcsetup module, and are used to construct the
rcParams global object which stores the settings and is referenced throughout
matplotlib.</p>
<p>These default values should be consistent with the default matplotlibrc file
that actually reflects the values given here. Any additions or deletions to the
parameter set listed here should also be visited to the
<codeclass="file docutils literal"><spanclass="pre">matplotlibrc.template</span></code> in matplotlib’s root source directory.</p>
