Unrepeated colors in multiple line plots using matplotlib

Question

I have 20 columns to plot using unrepeated colors. I would like to use tab20 color map. How do I use it?

I am finding all the online resources difficult to understand as I am still naive Python user.

Answer 1

In general this is how you can do it:

import matplotlib
cmap = matplotlib.cm.get_cmap(your_cmap) #your_cmap='tab20'
df.plot(cmap=cmap)
plot.show()
