expand_more To invert a color map in Matplotlib, attach the _r suffix to the color map, like so:
x = [1,2,3]y = [4,5,6]z = [100, 200, 300]plt.scatter(x, y, c=z, cmap=plt.cm.gray_r, s=200, edgecolor='black')plt.show()
Here, the key is that we used gray_r instead of gray, which reverses the color map.
The output we get is as follows:
Since we used the inverted color map, the higher the value, the darker it is.
