Seaborn heatmap top and bottom row are partially truncated [duplicate]

Question

I am trying to make a heatmap out of a dataframe, but the size of the blocks in the first and last row are not as equal as the blocks in the other rows. How can I fix this problem?

P.S. I am using python3 and seaborn library to produce the heatmap.

Answer 1

This issue has been raised and closed on the Seaborn github. The solution found there by ResidentMario & MaozGelbart was:

This was a matplotlib regression introduced in 3.1.1 which has been fixed in 3.1.2 (still forthcoming). For now the fix is to downgrade matplotlib to a prior version.

And later,

Matplotlib 3.1.2 has been released (also available for conda users through conda-forge using conda install -c conda-forge matplotlib=3.1.2). This fixes the issue.
