Thread: [Matplotlib-users] Engineering prefixed units in tick labels

In gnuplot, I can do the following:

set format x "%.0s %cHz"

...and this will set the x-axis labels (on a semilogx style plot) to
be "10 Hz", "100 Hz", "1 kHz", "10 kHz", etc.

Is there an easy way to do this in matplotlib? I spent a while in the
matplotlib.ticker docs, but couldn't find anything.

Cheers,
Jason

I ended up implementing this myself, it wasn't too hard. I've attached
the code if anyone else is interested. I don't know matplotlib that
well, so I don't know if there's much duplication of code in there.

I thought I'd CC the dev list in case others think it might be useful.
If not, sorry for the noise.

Cheers,
Jason

I am interested in this -i I just missed Jason's original email last
week so thanks for bringing it back to our attention.  Please post
this as a patch on the tracker

http://sourceforge.net/tracker2/?group_id=80706

since I don't have time to review it right now and I don't want it to
fall through the cracks.

Hi all,

I like this patch and it works fine. So if nobody is against including
this, I'll commit it in a few days.

I'll move the example from the class comment to an example script.

Cheers,
Reinier
