Troubleshooting
===============

* Please note that the TeX packages found in some Linux distributions and
MiKTeX installations are dramatically outdated. Make sure to update your
package catalog and upgrade or install a recent TeX distribution before
reporting problems.
package catalog and upgrade or install a recent TeX distribution.

* On Windows, the :envvar:`PATH` environment variable may need to be modified
to include the directories containing the latex, dvipng and ghostscript
executables. See :ref:`environment-variables` and
:ref:`setting-windows-environment-variables` for details.

* A limitation on Windows causes the backend to keep file handles that have
been opened by your application open. As a result, it may not be possible
to delete the corresponding files until the application closes (see
`#1324 <https://github.com/matplotlib/matplotlib/issues/1324>`_).

* Sometimes the font rendering in figures that are saved to png images is
very bad. This happens when the pdftocairo tool is not available and
ghostscript is used for the pdf to png conversion.

Troubleshooting
===============

* Make sure what you are trying to do is possible in a LaTeX document,
that your LaTeX syntax is valid and that you are using raw strings
if necessary to avoid unintended escape sequences.

* The ``pgf.preamble`` rc setting provides lots of flexibility, and lots of
ways to cause problems. When experiencing problems, try to minimalize or
disable the custom preamble before reporting problems.
disable the custom preamble.

* If you still need help, please see :ref:`reporting-problems`
