Seaborn heatmap not displaying all xticks and yticks

Question

I have a pandas dataframe of shape (39, 67). When I plot it's seaborn heatmap, I don't get as many labels on the X and Y axes. .get_xticklabels() method also returns only 23 labels.

matplotlib doesn't show any labels (only numbers) as well.

Both these heatmaps are for the same dataframe (39, 67).

Answer 1

To ensure the labels are visible, you have to set the parameters xticklabels, yticklabels to True, like so.

import seaborn as sns 
sns.heatmap(dataframe, xticklabels=True, yticklabels=True)

Here's the documentation for the heatmap function.
