<p dir="auto">It would be useful to have an API to set the linestyle cycle for an axes object, just like there is one for the color cycle. It would allow one to change linestyles independently of the color, which is useful for publications that need both color and black-and-white distinguishability.</p>
<p dir="auto">There seems to be some code duplication between tests and examples (e.g. <code class="notranslate">test_triangulation.test_tri_smooth_contouring</code> and <code class="notranslate">pylab_examples/tricontour_smooth_user.py</code>).  Perhaps it would make sense for the tests to simply import the relevant example file instead (which should trigger the plotting), in a context where <code class="notranslate">plt.show()</code> is patched to do nothing.</p>
