Grid of values into density plot in python

Question

I need to convert a grid of values into a density plot to make a picture that shows the structure of the silicon surface that was scanned. The file of values is called stm.txt and can be found here: http://www-personal.umich.edu/~mejn/cp/programs.html

I really can't figure this one out so I'm in some real need of help.

You can use numpy's loadtxt (https://docs.scipy.org/doc/numpy-1.10.4/reference/generated/numpy.loadtxt.html) to load your data, and then imshow (https://matplotlib.org/api/_as_gen/matplotlib.pyplot.imshow.html).

import numpy as np
import matplotlib.pyplot as plt

grid = np.loadtxt("stm.txt")
plt.imshow(grid)
plt.show()
