The example script 'testgdal.py' is crashing at the point of the 
basemap object instantiation:
m = Basemap(llcrnrlon=-119,llcrnrlat=22,urcrnrlon=-64,urcrnrlat=49,
 projection='lcc',lat_1=33,lat_2=45,lon_0=-95)
Assertion failed: (0), function query, file AbstractSTRtree.cpp, line 286.
Abort trap: 6
Is there a known workaround?
with basemap version 1.0.2
Best,
Michael

Timmie,
I would just use the fill_between method
http://matplotlib.org/examples/pylab_examples/fill_between_demo.html?highlight=codex%20fill_between

Hello,
how can I show the forecast error for a timeseries?
Example:
I am looking for displaying the blue area of:
http://t3.gstatic.com/images?q=tbn:ANd9GcR9yuoMhiDeqxJVIOmp0EDNS_Sgxhtv4Z-ohlWly6N7zcgf28QD
Or the violett areas on:

http://matplotlib.org/api/axes_api.html?highlight=error#matplotlib.axes.Axes.errorbar
Maybe as an envelope of
http://matplotlib.org/examples/pylab_examples/errorbar_subsample.html
Thanks for any pointers in advance and kind regards,
Timmie

Dear All,
I have some data files with numpy arrays stored in it in 2 columns. I want
to add a third column with just floating point numbers(not numpy array) and
plot them later with Matplotlib in 3d. How is it done? Could you please
illuminate me?
This is the concerned snippet of the code:
while *t < 1*:
 pp_za = pp_init + t*K*np.sin(K*pp_init)
# Periodic Boundary Condition
 for i in range(0,999):
 if pp_za[i] < 0:
 pp_za[i] = 2 - abs(pp_za[i])
 if pp_za[i] > 2:
 pp_za[i] = pp_za[i] % 2
 pv_za = +K*np.sin(K*pp_init)
 fname = 'file_' + str(t) + '.dat'
# Generating dataset for Phase Space diagram
 *np.savetxt(fname, np.array([pp_za,pv_za]).T, '%f')*
 t = t + 0.01
And the sample data generated is :
0.105728 0.098678
0.126865 0.118406
0.147998 0.138128
0.169126 0.157845
0.190247 0.177556
0.211362 0.197259
0.232469 0.216955
0.253567 0.236643
0.274657 0.256321
0.295737 0.275989
0.316806 0.295646
Precisely what I want is, I want to add the 't' (over which the while loop
is run) in the 3 rd column. 't' is float and constant for each looping. If
you know what a phase plot is(doesn't matter if you don't), I want to see
the phase plot evolving with time. Thus the need of a time axis and hence
plot with V(velocity-Yaxis), X ( Position -X axis) and t (Time-Z axis).Once
the data files are created properly, how to plot them using Matplotlib?
Regards,
Sayan

Answering my own question - the solution is to add a binding to the save
button, and prevent the event from propagating after calling new_save() by
adding 'return "break"' at the end:
def new_save(self, *args, **kwargs):
 print 'save_figure pressed'
 return "break"
get_current_fig_manager().toolbar.bsave.bind('<Button-1>', new_save)
I would still like to know why the mechanism that works for the Home button
fails for the Save button though...

Hmm, problems with html, will try again in plain text:
I'm trying to override the behaviour of the toolbar, with partial success.
This works:
from matplotlib.backend_bases import NavigationToolbar2
home = NavigationToolbar2.home
def new_home(self, *args, **kwargs):
 print 'home pressed'
 home(self, *args, **kwargs)
NavigationToolbar2.home = new_home
...but this doesn't:
from matplotlib.backend_bases import NavigationToolbar2
save_figure = NavigationToolbar2.save_figure
def new_save(self, *args, **kwargs):
 print 'save_figure pressed'
 save_figure(self, *args, **kwargs)
NavigationToolbar2.save_figure = new_save
Having actually created a figure, I can get a bound method for save_figure:
get_current_fig_manager().toolbar.save_figure()
This I can override, and call my override function successfully from my
script - but pressing the save button on the toolbar doesn't call my
function...
I'm running matplotlib 1.1.1rc and python 2.7.3
Thanks,
Will
