Log x-scale in imshow :: matplotlib

I have a table which looks like this

enter image description here

I have the highlighted part as a matrix of which I want to do an imshow. I want to have the x-scale of the plot logarithmic, as one can understand by looking at the parameter values in the topmost row. How to do this is matplotlib?

You want to use pcolor, not imshow. Here's an example:

import numpy as np
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
Z = np.random.random(size=(7,7))
x = 10.0 ** np.arange(-2, 5)
y = 10.0 ** np.arange(-4, 3)
ax.set_yscale('log')
ax.set_xscale('log')
ax.pcolor(x, y, Z)

Which give me:

log pcolor
