How To Display Ticks In Plain Number For Seaborn Heatmap With Logarithmic Scale?

I am generating a heatmap using seaborn which has a logarithmic scale. How can I change the colorbar labels from scientific notation to plain number. import math from matplotlib.co

Solution 1:

seaborn plots are wrappers around matplotlib so I would suggest this

ax.ticklabel_format(style='plain')

Solution 2:

The following codes helped.

For the first part of the problem adding "format" in cbar_kws parameters helped. (https://stackoverflow.com/a/35419495/8881141):

import matplotlib.ticker as tkr
formatter = tkr.ScalarFormatter(useMathText=True)
formatter.set_scientific(False)

ax = sns.heatmap(corr, square=True, mask=mask, cmap=cmap_type, linewidths=.5, vmax=vmax, vmin=vmin, norm=log_norm, cbar_kws={"ticks": cbar_ticks, "format": formatter}, center=center)

For the second part, which is caused due to a bug in matplotlib, adding the following removes the minor ticks. (https://stackoverflow.com/a/65676007/11897903):

ax.collections[0].colorbar.ax.yaxis.set_ticks([], minor=True)
