Matplotlib throws warning message because of findfont - python

Tags:

I want to plot a basic graph, basically consisting of two lists of the form x = [1,2,3,...,d], y = [y1,y2,...,yd]. after using_ pyplot.plot(x,y) I get a huge amount of warning messages referring to findfont errors (see below..)

I just installed matplotlib. All the threads I could find refer to changing fonts manually and having warning messages popping up. I did not do anything like that. I just installed the package and that is it.

I am using pycharm, python 3.6 and windows for programming.

How do I get rid of Matplotlib warnings?

Use warnings. filterwarnings("ignore") to suppress the warning. To display the figure, use show() method.

Where is Matplotlib font cache?

It may be located under ~/. matplotlib/fontList. cache or ~/. cache/matplotlib/fontList.

How do I add fonts to Matplotlib?

Unzip the file and copy the path to the folder. From here, we can use the font_manager from Matplotlib to add fonts from a file. You'll want to add the fonts one by one inside the loop. Once added, we'll set the entire Matplotlib font family to Merriweather, so we don't have to specify the font everywhere manually.

Just as an alternative solution, you can disable the matplotlib font manager logger.

logging.getLogger('matplotlib.font_manager').disabled = True
