How to change the different colors used by a Matplotlib plot
• 1 minAnother way to change the colors is to change the colormap of the chart you are plotting.
This will give you a list of colors in RGBA format.
viridis = cm.get_cmap('viridis', 8)
How to use the color map
Here is an example on how to use the color map with a scatter plot.
fig, axes = plt.subplots(1,1, figsize=(6,4))
axes.scatter(range(8), range(8), c=range(8), cmap=viridis)
fig.tight_layout()
plt.show()
By specifying the colormap (cmap) you give Matplotlib the reference colors.
Further, by specifying the color (c) parameters, you tell Matplotlib which color index he should use for the points we have.
The result

Here you are! You now know how to use a colormap!
