Rather than using a large size in inches, increase the value of the 
"dpi" kwarg to "figure()". When it matches your actual screen dpi, the 
display on the screen should be correct in the specified dimensions in 
inches, *provided* those dimensions plus the margins (toolbar etc.) fit 
on your screen. If they don't, then decrease the dpi (scaling the 
displayed figure down) until they do.

Arnaldo,
 
Thanks for the response. I figured it out. Figsize although the units are inches it does not correspond to inches on the display. I had to go up to 23 X 12 to get a large image on the display. If I want to fill the display what parameters should I use? I’m looking for a large map not a large frame size. Maybe I’m not understanding the functions of the various arguments used.
 
Regards,
Marty

Hi Martin,
 
Have you tried to save your figure and check if it does not enlarge your figure?

Without seeing the code, it would be hard to tell what is wrong. Setting
the figure size should work. I do this all the time myself.
As for converting map coordinates to inches, are you talking about inches
of the display? or inches of the map (as opposed to km or miles)?

Hello,
 
I'm a new user to both python and basemap. I've got my map working OK, but
would like to make it larger on the display. I've tried the height and width
parameters in the map definition (m=basemap(.) and
plt.figure(figuresize=(x,y)). Neither appear to have any effect on the size
of the map.
 
Is there an easy way to convert map coordinates to inches?
 
Thanks,
Marty

Ahh, the hashes were the problem!
Thanks for your help.

You can't use the hash symbol when doing colors as a hex in an rcfile. The
rcfile parser is so simple that it treats it as a comment. Don't drop the
quotes.

Hi,
I'm trying to set my default color cycle in my matplotlibrc using
axes.prop_cycle. The documentation (as far as I could find...) only gives
examples like
axes.prop_cycle : cycler('color', 'bgrcmyk')
And then the comment below says, cryptically:
# as list of string colorspecs:
# single letter, long name, or
# web-style hex
But I have tried all sorts of variatns on:
axes.prop_cycle : cycler('color', ['#e41a1c', '#377eb8', '#4daf4a',
'#ff7f00', '#a65628', '#f781bf', '#999999', '#984ea3', '#ffff33'])
But I always get an error upon importing matplotlib. Is there any doc on
how to do this properly? Is this even supported?
Thanks,
Julian

You can use the warnings module from the Python standard Library.
import warnings
warnings.filterwarnings(action='ignore')
This will silence all Python warnings. The signature for
warnings.filterwarnings
<https://docs.python.org/2/library/warnings.html#the-warnings-filter> can
also be used to only suppress some warnings.

I recently upgraded to vers. 1.5.0 and I am now getting some warning messages. 
For example:
D:\Python27\lib\site-packages\matplotlib\backend_managers.py:62: UserWarning: 
Treat the new Tool classes introduced in v1.5 as experimental for now, the API 
will likely change in version 2.1 and perhaps the rcParam as well
 'version 2.1 and perhaps the rcParam as well')
D:\Python27\lib\site-packages\matplotlib\backend_tools.py:78: UserWarning: Treat 
the new Tool classes introduced in v1.5 as experimental for now, the API will 
likely change in version 2.1, and some tools might change name
 'version 2.1, and some tools might change name')
How can I keep these messages from being displayed (at least temporarily)?
--V

Dear all matplotlib/basemap users,
I have made a plot like below using matplotib and basemap. The problem is
that I wan to add also parallel ticklabels for the circles higher than 40N.
Anybody knows how to achieve this? I checked the yticklabels for the map
axes but find it's not implemented as an original polar plot in matplotlib.
Thanks a lot in advance!

Have you tried setting "useblit=False"? If that works, I wonder if we
accidentally broke something in the recent widget interactivity work...

I am selecting a region of a color plot with span selector, and I would like the selected region to stay highlighted. I found the span_stays flag, but the selection rectangle still disappears after I release the mouse.
Any help is appreciated.
Thanks,
Ned
My backend is 'TkAgg'
I am running the script from python3.4 at the command line, my version is:
Python 3.4.3 (default, Jun 19 2015, 05:46:30)
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> print(matplotlib.__version__)
1.5.0
code example:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import SpanSelector
test_data = np.random.randn(1000, 1000)
fig, ax = plt.subplots()
ax.imshow(test_data)
def selection(x1, x2):
 """This function isn't the point"""
 pass
span = SpanSelector(ax, selection, 'horizontal', useblit=True,
 rectprops=dict(alpha=0.5, facecolor='red'), span_stays=True)
plt.show()

This all makes sense - thanks so much for your help!

You will select the TkAgg backend which is interactive and normally installed.

That makes sense. The agg backend is a non graphical backend intended for
saving image output. I don't know why this is the default one on your
system.

...
```

Are you logged in on another machine? If so, you might be connected via the
'ssh' command and not 'ssh -X'.

Can you try to check which backend you are using
Do something like
>>> import matplotlib
>>> matplotlib.get_backend()
after your plot. It is possible that your machine is set to use a non
graphical backend

Here's some output from an ssh -Y to another machine - I also get the same

Sorry but the parentheses have not gone missing in your copy paste. The
line below will only be printed if you don't have any parentheses after the
function. Can you try again and show the output of actually calling
plt.show()?

Apologies, the parentheses must have got missed off when I copied and
pasted the output from my terminal.
Same issue though, I don't get any plots come up. This always used to work,
and works for my colleagues!

You're missing a pair of parentheses. Without it, you're just referring to
the function itself.
plt.show()

plt.show is a function. You are not calling it just displaying it. Try
doing plt.show()
