Correlation heatmap

Question

I want to represent correlation matrix using a heatmap. There is something called correlogram in R, but I don\'t think there\'s such a thing in Python.

How can I do

Answer 1

1. Use the 'jet' colormap for a transition between blue and red.
2. Use pcolor() with the vmin, vmax parameters.
