[Matplotlib-users] matplotlib basemap streamlines plot
Hi all, tried to plot a streamline with matplotlib. So far it work's.

Re: [Matplotlib-users] Plotting maps with matplotlib-basemap very slow
Hi,
creating a pickle of the Basmap instance was the correct way. Now it works
great! Thank's all for that quick and helpful support!
Solution as follows:
m = Basemap (...)
pickle.dump(m,open('map.pickle','wb'),-1) # pickle it
for ... :# loop to generate x plots
pickle.load(open('map.pickle','rb')) # load here the above pickle
# do some other stuff
Regards
Sappy85

[Matplotlib-users] Plotting maps with matplotlib-basemap very slow
I would like to draw very, very simple maps of only europe in matplotlib /
basemap, which takes very much time (around 10 seconds!). This is just
unreal!? Setting of resolution is only l (low).
I need to plot hundreds of those maps every few hours. This would be
impossible!!? :(
Here is the very simple code:
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap
m = Basemap(projection='stere',lon_0=5,lat_0=90.0,rsphere=6371200.,\
llcrnrlon=-25.0,urcrnrlon=72.0,llcrnrlat=26.0,urcrnrlat=65.0,resolution='l')
m.drawcoastlines(linewidth=0.2)
m.drawcountries(linewidth=0.2)
plt.savefig('/var/www/map.png')
Hope you can help! :(
Regards

Hi, yes that helps a lot, reading in the boundaries from a shapefile. But does anybody know, how avoid the double inner borders? Coastlines seem to have a thinner border.

Re: [Matplotlib-users] Pyplot contour plot - clabel padding
Hi @all, the problem seems to be solved. Thanks Jody! What i have done: 1.) check out the xlim and ylim after clabel call *xmin, xmax = plt.xlim() # return the current xlim ymin, ymax = plt.ylim() # return the current ylim print xmin,xmax print ymin,ymax* 2.) use and set these limits before clabel call: *plt.xlim(0.0,6475051.47849) plt.ylim(0.0,4412688.31468)* Yes, that's it. Very confusing! I do not understand why that only goes so awkward? Thanks so much!

Hi diedro,
try something like this:

ax.add_patch(poly)
plt.show()

[Matplotlib-users] Pyplot contour plot - clabel padding
I have trouble with matplotlib / pyplot / basemap. I plot contour lines (air pressure) on a map. I use clabel to show the value of the contour lines. But the problem: the padding between the value and the contour line is too much. I have found the parameter inline_spacing, which i have set to zero. But there is still to much free space.

[Matplotlib-users] Plotting with a custom color-vector
Hello,
I've created a map with matplotlib-Basemap and will have an animated gif by
drawing my special points / markers one by one in the plot. That work's
fine.
Now the markers should have a special color from a generated color-vector.
In this vector are values from (0.0-1.0) for grey values.
The data-vector is as follows: index 0,1 the lat and lon information, index
2 the gray values.
/Problem/: Passing the color vector to the plot command, cause this error:
*raise ValueError('third arg must be a format string')*
This is the important part of my code:
Any ideas? Regards John
