I'm glad that worked for you. Unfortunately, I don't use basemap, so I can't really help with this additional complication. I'm sure someone else on the list will be able to help you out, though.
Best,

Hi Tony,
Thanks, that works pretty good!
However... it seems that "drawcoastlines" creates a border if I am not
"zoomed out" far enough. (i.e., the coastline is out of bounds).
Do you know how I could turn that off?
Thanks again!

There's probably a shorter way, but I have a small function that I use to turn off the frame or border around an axes.
def clear_frame(ax=None):
 if ax is None:
 ax = plt.gca()
 ax.xaxis.set_visible(False)
 ax.yaxis.set_visible(False)
 for spine in ax.spines.itervalues():
 spine.set_visible(False)
Best,

Hello again,
I am not sure if this is a matplotlib question, or a basemap one. The
sample code I found on Google for this either broke my script or
didn't change the end result.
I am attempting to turn the border (frame?) off altogether. Here is
the script, with some sections kept out for brevity:
----
import sys
import matplotlib
matplotlib.use('agg')
from mpl_toolkits.basemap import Basemap
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(2.56,2.56),dpi=70,frameon=False,linewidth=0)
fig.set_frameon(False)
# as you can see, above are some of attempts at turning the border off
plt.subplots_adjust(left=0, bottom=0, right=1, top=1, wspace=None, hspace=None)
m = Basemap(....)
m.drawcoastlines()
fig.savefig("test.png")
-----
Thank you in advance once again!

I'm setting up an axes in which I configure the axis objects with my desired
tick locators and formatters and later configure the spines, setting their
bounds, visibility, and positions. I was surprised that setting the spine
position wiped my axis formatting by calling axis.cla(). Is it necessary that
the spine must clear the registered axis when its position is changed? (The
same clearing occurs in Spine.register_axis(), but in my case that occurs at
axes creation and doesn't cause me any trouble.)
