matplotlib/seaborn: first and last row cut in half of heatmap plot
Unfortunately matplotlib 3.1.1 broke seaborn heatmaps; and in general inverted axes with fixed ticks.
This is fixed in the current development version; you may hence
- revert to matplotlib 3.1.0
- use matplotlib 3.1.2 or higher
- set the heatmap limits manually (
ax.set_ylim(bottom, top) # set the ylim to bottom, top
)
Its a bug in the matplotlib regression between 3.1.0 and 3.1.1You can correct this by:
import seaborn as snsdf_corr = someDataFrame.corr()ax = sns.heatmap(df_corr, annot=True) #notation: "annot" not "annote"bottom, top = ax.get_ylim()ax.set_ylim(bottom + 0.5, top - 0.5)
Fixed using the above and setting the heatmap limits manually.
First
ax = sns.heatmap(...
checked the current axes with
ax.get_ylim()(5.5, 0.5)
Fixed with
ax.set_ylim(6.0, 0)
