Troubleshooting

Describe your environment

Describe your question

I want to make a wordcloud picture of Chinese words using matplotlib. But the output picture is garbled and Chinese words cannot display. Even I have tried the two potential solutions (### https://github.com/hupili/python-for-data-and-media-communication-gitbook/blob/7fad4125cbde74714dbe0da1f71649680d24d7ee/module-matplotlib.md and https://github.com/hupili/python-for-data-and-media-communication/blob/93ff76364e0374aaacf75f766efb4736d7a357b7/matplotlib-examples/Chinese%20Font.ipynb) in Github, they do not work.

The minimum code (snippet) to reproduce the issue

You need to load the font in the wordcloud function. It does not go through the matplotlib. That is why even if you can plot Chinese on matplotlib, the wordcloud is still problematic.

    wc = wordcloud.WordCloud(background_color="white",max_words=3000,max_font_size=60, random_state=40)

It is better to put into module-wordcloud. In essence, it is the wordcloud issue, not matplotlib issue.

After the new FAQ page is created, you can link from module-matplotlib to module-wordcloud, leaving a message:

There is a similar issue about Chinese characters (CJK characters) when you use wordcloud. Please refer to this section for the solution.

We keep on improving categorisation and inter-linking between those topics.
