<h3 dir="auto">Bug report</h3>
<p dir="auto">Normally, systemwide configuration files at not completely ignored just because a local/user configuration file exists.  But MPL will ignore default configuration values in /etc/matplotlibrc if a user matplotlibrc is found.</p>
<p dir="auto">The documentation states that user configuration files are searched first, which, if you think about it, only makes sense if the configuration files are all <em>mutually exclusive</em>.  But, this is not stated or acknowledged in the documentation, elsewhere.  Since mutual exclusivity is abnormal behavior for configuration files, can you please, at least, make this more clear in the documentation?</p>
<p dir="auto">Is it possible to implement more conventional behavior where the system-wide defaults are always read, if they exist, and the user-specific or local configurations override them?</p>
<p dir="auto">Only one matplotlibrc file is loaded instead of loading them in order of decreasing scope. So when I added a matplotlibrc file in my home directory it unexpectedly changed the backend that was being set in <code class="notranslate">INSTALL/matplotlib/mpl-data/matplotlibrc</code> because that file was no longer being loaded. I expected matplotlib to load the global (install) config and then apply my config on top of that.</p>
