I want to use numpy.arange() to create multiple arrays, and then I want to join
these arrays (or individual elements) to the final array without repeating
existing elements (create a 'union' from 2 or more arrays or individual
elements).
example:

Im having an issue with the plotting of contours using basemap.
My contours are incorrectly being plotted on top of my basemap
coastlines&continents.
Ive attached an image as an example:
Note that the red contour lines near land areas are OVERLAPPING the coastlines
& continents, instead of b

it appears to be a masked array, but a "customized" one, that's being created
from the interface to the external program Im working with (application named
GrADS). here's some more info...
[7] ga-> Z?
Type: GaField
Base Class:
String Form:
[[0.0 0.0 0.0 ..., 0.0 0.0 0.0]
[0.0 0.
Please disregard this question, as a solution was found to this problem using
the 'BoundaryNorm' function.

This is related to a previous question I had about colormaps;
Im looking for a method to evenly split up a colormap into an RGB colors array.
something like:
def cmap_to_array(cmap,N):
...
mycolors=cmap_to_array(cm.jet,20)
lev=np.arange(1,20,1)
cs=contourf(Z,lev,colors=mycolors)
...

Hi,
I would like to know how I can pass an array of levels and also a colormap to
the contour() function and have the levels span the entire colormap. example...
if I do the following
Lv=(1,3,5,6,7,8,9,10,12,14,16,18,20,25,30,35,40,50,75)
cs=plt.contourf(X,Y,waveheight,Lv,cmap=cm.jet
Anyway, thanks again for the help,

Im experiencing very poor performance when using the 'quiver' function over
relatively large grids.
Im using quiver to plot wind 'u,v' data over a lat/lon grid using basemap.
quiver performs decently over small lat/lon ranges, such as a bounding box of
lat(0-30),lon(-120- -100), but when I try
Hi,
I need help doing the following:
I need to create a square png image (256x256 pixels) with NO margins. I need my
plot area to completely fill this 256x256 box, regardless of what the plot's
aspect ratio should be; i.e., I want the plot area stretched or compressed
