Matplotlib: disable powers of ten in log plot

Question

Is there a simple way to make matplotlib not show the powers of ten in a log plot, and instead just show the numbers? I.e., instead of `[10^1, 10^2, 10^3]` display `[10, 100, 1000]`? I don't want to change the tickmark locations, just want to get rid of the powers of ten. This is what I currently have: I can change the labels themselves via `xticks`, however I then get mismatching fonts or sizes for the y tick labels. I am using TeX for this text. I've tried the following: ``` xx, locs = xticks() ll = [r'\rm{%s}' % str(a) for a in xx] xticks(xx, ll) ``` This gives the following result: In this particular case, I could use the same LaTeX roman font, but the sizes and looks are different to those in the y axis. Plus, if I used a different LaTeX font in matplotlib this is going to be problematic. Is there a more flexible way of switching off the power of ten notation?

Accepted Answer

Use a `ScalarFormatter`:

```
from matplotlib import rc
rc('text', usetex=True)
rc('font', size=20)

import matplotlib.pyplot as plt
from matplotlib.ticker import ScalarFormatter

fig = plt.figure(figsize=(10, 6))
ax = fig.add_subplot(111)
ax.semilogx(range(100))
ax.xaxis.set_major_formatter(ScalarFormatter())
plt.show()
```
