How to add a colorbar to kdeplot and jointplot Question: When generating bivariate plots like hexbin, pandas generates a legend explaining frequency value for each color shade: pokemon.plot.hexbin(x=’HP’, y=’Attack’, gridsize=30) I cannot find a similar way to generate such a legend for jointplot and kdeplot in seaborn: sns.jointplot(data=pokemon, x=’HP’, y=’Attack’, kind=’hex’) sns.kdeplot(pokemon[‘HP’], pokemon[‘Attack’], shade=True) How …
Properly adding a second set of ticks to python matplotlib colorbar Question: I have a figure with three subplots. The top two subplots share a similar data range, while the bottom one shows data with a different data range. I’d like to use only one colorbar for the whole figure by having ticks for the …
Log scales with Seaborn kdeplot Question: I am trying to make a nice free energy surface (heat map) using Seaborn’s kdeplot. I am very close but can not figure out a way to change the color bar scale. The color bar scale is important since it is supposed to represent the difference in energy at …
How to "cut" the unwanted part of a colorbar Question: Say you create an image with imshow like this: plt.set_cmap(‘viridis’) im=plt.imshow(mydata, interpolation=’nearest’,origin=’lower’) plt.title(‘mymap’) cbar=plt.colorbar() a=round(mydata.max(),0) cbar.set_ticks([17,23,a]) cbar.set_ticklabels([17,23,a]) Say you have a continuous-like dataset where most values are 0, but then there’s a jump leading to the range of highest values. How do you “cut” the …

How to add a colorbar to a seaborn kdeplot Question: I want to create a Kernel-Density-Estimation with seaborn.kdeplot with a colorbar on the side. import matplotlib.pyplot as plt import seaborn as sns import numpy as np; np.random.seed(10) import seaborn as sns; sns.set(color_codes=True) mean, cov = [0, 2], [(1, .5), (.5, 1)] x, y = np.random.multivariate_normal(mean, …
Matplotlib colorbar ticks on left/opposite side Question: One could generate a vertical colorbar like so(simplified): import matplotlib.pyplot as plt import matplotlib as mpl plt.figure() c_ax=plt.subplot(111) cb = mpl.colorbar.ColorbarBase(c_ax,orientation=’vertical’) plt.savefig(‘my_colorbar.png’) Resulting in something like this(rotated for space reasons): Is it possible to get the ticks labels on the opposite side? Asked By: M.T || Source Answers: …
Top label for matplotlib colorbars Question: By default matplotlib would position colorbar labels alongside the vertical colorbars. What is the best way to force the label to be on top of a colorbar?
