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
Hi Jason,
I think I found a solution. It might not be the best, but at least it works
for me using as FuncFormatter. Please have a look at the attached program and
the screenshot.
Kind regards

Hi,

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.

EngFormatter.py (2.21 KB)
Hi Jason, Hi list,
First of all let me say I like the EngFormatter of Jason.
Are there plans to incorparate it into matplotlib?
I cannot find any indication for this in current svn, but I would like to see
the EngFormatter in matplotlib. Therefore I tried to include Jasons proposal
into the ticker.py as a new class EngFormatter including the
method 'self.format_eng'.
I made some changes, which might break some of Jasons ideas, but I cannot see
(1) why we need the LogFormatter as base class instead of Formatter?
(2) why one should decide for only decade-labels. Therefore I removed the
corresponding if-statement. It causes errors () if you use an axes
including '0', which could be useful for eng-formatting, too.
(3) Could we always use format_str = "%g %s" instead of
specifying 'places'? Because of successive zomming I don't want to
specify 'places' before calling 'plt.show'. Therefore I introduced "places
=None" to use "%g %s".
I attached the new ticker.py and a diff against current svn (I'm sorry I
couldn't resist to add some white spaces).
Any comments are welcome.
Kind regards,
Matthias Michler

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
