问题
I need to set the max value on the seaborn heatmap cbar to 2. I've tried:
cbar_kws = { 'ticks' : [0, 2] }
sns.heatmap(tiles, robust=True, fmt="f", cmap= 'RdBu_r', cbar_kws = cbar_kws)
But this doesn't work and the documentation isn't very clear. How would I do this properly?
回答1:
I think you want to use the vmin and vmax parameters for the heatmap, as described in the docs:
vmin, vmax : floats, optional
Values to anchor the colormap, otherwise they are inferred from the data and other keyword arguments.
sns.heatmap(tiles, robust=True, fmt="f", cmap='RdBu_r', vmin=0, vmax=2)
