Hello,
I am creating a plot with multiple y-axis (up to 6) and twinx works pretty
well. The problem is that there are too much wasted spaces used up by the
axes. Since I have multiple axes, it cuts into the amount of space available
for the plot area. I need to know how I can squeeze some sp
BTW: I tried to use set_position to change the position of the axes label as
suggested by previous posting. No effect.

Hi all,
I am new to matplotlib. I like to know how to create a plot that contains
several y-axis (up to say, 6) with only 1 x-axis (similar to the two_scales.py
type plot but with all of the y-axis on one side). I know you can create
multiple single curve plots on the same page but that's not
I am having trouble with axes and grids in the y-direction.
I have a 3 rows x 2 colums figure and I like to have 5 major Y divisions or 4
grid lines for each of the graphs. 5 of the 6 graphs came out properly. For
instance, for a Ymin=12, Ymax=17, I get grid lines at y=13, 14, 15, and 16.
Hi list,
The tutorial indicated that I can use gca to get at the grid by doing a:
glines = getp(gca(), 'gridlines')
but when I do that, I get a "Subplot instance has no attribute "get_gridlines".
How do I get to the grid object?
Thanks,

Hi list,
I am still fairly new to Matplotlib.
If I use the default settings, after creating a plot, and save the file, I get
a .png file that looks really ugly. However, if I view the plot at the screen
first (using the show() command), maximized the plot, and then save the file, I

Thanks for the reply, Darren.
I didn't post the plot because I don't know if the list accept email
attachments, and I don't have any space on the web for file sharing.
I'll try to figure out a way to post the plots.
BTW: I called savefig with the filename, and a dpi of 600 and nothing else.

Okay, I tried saving using the postscript format, and I end up with the "ugly"
plot also. In fact, if I maximize the plot and then save as .ps file, I get

correct but it means I end up with the same font, and dimension
Okay, I posted the "ugly" vs "pretty" plots at:

I stripped out most of the titles and subtitles but I think you can still see
the difference between the two. (Don't worry about the middle unintelligble
part).

I am getting an "invalidrestore" from the printer when I print a figure created

about axes. See:

Most likely Word. It's very picky. I have .eps
Actually, Gimp is the problem. It's obvious they don't have a very good

This is simply too good to be true. I played with manupulating MPL plots using
Inkscape and man, somebody ought to include this in the MPL FAQ. I can move
everything around by elements, touch-up or remove things I don't want, scale
it, rotate it, you name it.
And then I can save the file in
Sorry. Just discover that saving the file in emf format under Inkscape and
