I am on my computer at home and can't recreate my problem. I don't know 
what I did wrong last night. I could still use help though on the 
legend refresh stuff in my other message.

This morning on my office computer I don't seem to have the same 
problem. (I will see if I can recreate my problem on my laptop at home 
later.)
I do have one new problem though. After adding the second plot, I need 
to refresh the legend of the first plot because the plot on twinx wrote 
over it. Any calls to legend seem to be working with the lines that are 
drawn on twinx. I could avoid this problem and make a slightly nicer 
looking plot if I could first draw on the twinx axis (with the y-axis 
ticks on the right) and then draw on the "normal" axis (with the y-axis 
ticks and label on the left). Is this possible?
And can I make one legend that includes the plots from both axes?
Thanks for your help John. I think I am getting close to a really nice 
graph with a lot of useful information on it.

Hello Jeff,
we had exactly the same problem and Doug Swesty had the right answer (BTW
thanks for this!) to it:
http://sourceforge.net/mailarchive/message.php?msg_id=12999739
According to this post all you have to do is:
plot1 = gca()
setp(plot1.get_xticklines() + plot1.get_yticklines() , mew=2.0, mec='g')
Bye,
Martin

Hi all,
after upgrading matplotlib to 0.84 (with python 2.4.1) I get the 
following warning message:
> /sw/lib/python2.4/site-packages/matplotlib/backends/backend_gtk.py: 
> 998: GtkWarning: Could not find the icon 'gnome-fs-home'. The

AFAICU the message is related to the gnome icons, but I've checked 
and the last avaible version of the gnome icons package is installed 
on my system. Anyone here can help me in fixing this?
Thanks,
 Andrea.

Hi,
I just started to use matplotlib for a small project involving graph 
generation. I'd like you to help me to solve a simple problem: I assign 
to axes values that range from 0 to 100 bilion. The library approximate 
the values to fit correctly the layout, an it places the exponent that 
should be used to retrieve the right value on top of the axes. I need to 
change this behaviour, and I'd like matplotlib to show the full exponent 
(1000 instead of x1e3 for example).
How can I do that?
bye,
Gabriele

Please post a free-standing, complete example which replicates the
bug.
Thanks,

It appears that this feature is available through the twinx() function 
according to:
http://matplotlib.sourceforge.net/faq.html#TWOSCALES
(the link on this page is broken, but I have the file in some examples I 
downloaded from somewhere else on the matplotlib page.)
I created the second plot using:
figure(1)
subplot(211)
ax2=pylab.twinx()
pylab.semilogx(freq,iobode.coh,'k')
It seems like once I called the twinx function, the x-axis settings that 
 where on the original axis are ignored and I can't seem to change the 
axis settings. pylab.axes([0.1,30,0,1]) returned an error: 
RuntimeError: Transformation is not invertible
I tried calling the ax2.set_xlim((0.1,30)) function but it doesn't seem 
to do anything.

If it helps clarify what I mean, attached is a plot I made in excel (I
really don't want to use excel). The y-xis on the left goes from -60 to
80. The one on the right goes from 0-1.

Is it possible to overlay two plots with different y-axis limit? I 
think excel calls this plotting a data set with a secondary y-axis. I 
want to overlay a bode plot with its coherence and the y-axis limits for 
the two will be very different. I don't want to plot one above the 
other with a subplot, but actually overlay them on the same plot.
(and I want to do it on a semilogx).
Thanks,
Ryan
