Set ticks that aren't at powers of some base on a loglog plot

Question

I'm plotting over a small range, but I'm using a log-log plot to make certain features more clear. How can I set ticks on the x-axis that aren't powers of any base, but multiples of some value?

Basically, I want labels on the x-axis at the values [x * 1E13 for x in range(1,10)].

Is the plot meant for interactive use? In other words; does the mouse-over values in an interactive plot have to be precise? This makes a difference as to how to format the ticklabels on the x-axis. Also, please include your code! — sodd, May 31 '13 at 13:45

You can use a FixedLocator and call set_major_locator on your x axis with it.

my_xaxis.set_major_locator(FixedLocator([x * 1E13 for x in range(1,10)]))

If you want labels, you need to set them manually:

labels = FixedFormatter(['{:5.2e}'.format(x * 1E13) for x in range(1,10)])
my_xaxis.set_major_formatter(labels)

Along with `major_locator` you might need to set `major_formatter`. – Andrey Sobolev May 31 '13 at 10:04
