Question

How to fill black texture to distinguish bars not use color in matplotlib? I can't find any example. just like this texture in R

Answer 1

The matplotlib.pyploy.bar object has the property hatch , which controls the kind of thing you are after.

Check out the doc for more info https://matplotlib.org/devdocs/api/_as_gen/matplotlib.pyplot.bar.html

There is a really nice example of this in the matplotlib docs. https://matplotlib.org/examples/pylab_examples/hatch_demo.html

You may need to tweak the example to match your specific neads though.
