Be sure to use vector figures (pdf or pgf) instead of raster ones (png, jpeg).<br>
See [https://timodenk.com/blog/exporting-matplotlib-plots-to-latex/ https://timodenk.com/blog/exporting-matplotlib-plots-to-latex/] on how to export matplotlib to pgf.

* <code>!</code> means to ignore some placement limitations
* <code>h</code> mean to place the figure here
* <code>t</code> means top of the page.
* <code>b</code> means bottom of the page.
* <code>p</code> means to place it on a figure only page.
If you add the [https://ctan.mirrors.hoobly.com/macros/latex/contrib/float/float.pdf the float package], you can also use <code>[!H]</code> which is a more strict version of <code>[!h]</code>.
