Hello,

When I save the figure as EPS, no text shows up.
The problem occurs with the example "embedding_in_wx2.py" and when I use 
MSWord to show the eps file.

Is it a problem with MSWord ??

Thanks by advance.

Hi,

I am searching for a solution of the axis aspect in 3d plots, too.

This does not seem to work. At least I am not getting it to work. This 
command does not seem to be applied to the 3d axis. Do you have an 
example where this works on 3d axis?

Regards
Paul.

Ok, then I guess I am still not seeing how to accomplish what I'm 
looking to do.
I have a yaxis which has ticks every 0.2, and I need it to be every 0.4.
which function do I use to change that?  Can I use that function to 
change the font size of the tick labels?
It turns out there's an (undocumented) function called set_xticks in the 
mplot3d api (I deduced its existence from the existence of xticks in 
pyplot) but I'm not sure how to work it.  I thought it would set the 
values to place the tickmarks at, so I tried:
ax.set_xticks([-0.4,0.0,0.4,0.8])
but that just squashed up the plot.

I also need to move the labels around on the 3d plot so they can be 
clearly seen in the figure.  How can I tell the axis label where to be 
in reference to the axis itself?

Cheers
Michael

I'm pretty sure your problem is not generally related to matplotlib, all the 
examples you mentioned and the one you sent me by e-mail worked for me. Maybe 
you try a different version or a different operating system for your scripts.

In the second case, after x, nothing really happened. The program 
resecuted the def it was in.

Well, that didn't quite work.

I tried
...
fig=figure()
...
fig.close()
show()

and
show()
fig.close()

In the first case, I got the error msg:

Thanks. It seems most example of matplotlib end with show(). In fact, 
all may end that way, at least the short ones.

Yes, that did it. Thanks. Some of that code I copied from an example, 
the ax1 part. I guess it's related to subplot. The 1 on ax doesn't make 
much sense to me. Maybe there was an ax2 in the original, so there were 
two subplots. So it looks like to manipulate the subplot, one uses ax1 
with calls to color the end of lines, or changes the line to dashes?  
Maybe labels and titles?  Although that may be the way pyplot works.
