Hi all
FYI, the streamplot example does work with the dev. version of
matplotlib (that I pulled out from github, more specifically
matplotlib-matplotlib-v1.1.1-rc2-664-ga2d44d5.zip)
thanks
Nico

Content-Type: text/plain; charset=windows-1252Hi all
I have installed successively basemap 1.0.3 and 1.0.4 on top of my EPD
7.3 (linux x86_64) running on a linux ubuntu 11.10.archives downloaded from
matplotlib - Browse Files at SourceForge.netMy matplotlib version is 1.1.0 and I have checked that indeed the call
to mpl_toolkits.basemap returns the correct version (I have installed
successively 1.0.3 and then cleaned up and installed 1.0.4)the traceback is
"""
Traceback (most recent call last):
File "streamplot_demo.py", line 32, in <module>
m.streamplot(x,y,udat,vdat,color=speed,linewidth=2,density=2,cmap=plt.cm.spectral)

line 3370, in streamplot
ret = ax.streamplot(x,y,u,v,*args,**kwargs)
AttributeError: 'AxesSubplot' object has no attribute 'streamplot'
"""the doc string for streamplot_demo.py (in the example folder of the
basemap1.0.4 sources) states that it requires the vectorplot scikit,
which I have installed but been unable to get working (complains about
missing lic_internal module ...)what is confusing is that the entry for streamplot_demo in the README
(from basemap_1.0.4-examples) states that it "shows the new matplotlib
streamplot method to visualize wind fields"Do I need to upgrade matplotlib to the development version ?
thanks a lot in advance for any help on that one ...

Yes. Streamplot hasn't been officially released yet. Maybe Basemap should
check for the function first?Ben Root

so streamplot "will" be part of a future stable release of matplotlib
then ? one does not need the scikits.vectorplot installed ?I will try and pull the latest development version of matplotlib and
install it (linux and mac os X), and then come back to the list to
give some feedbackscheers

lic_demo.py. I should not have included that example in the release at
all, since streamplot is not in the released version of matplotlib.-Jeff

Content-Type: text/plain; charset="iso-8859-1"Hi,
Is boxplot supposed to be able to handle nan?
I assumed it would, but got some unexpected results when trying so.
In the example below i try to create boxplot for three lists a,b,c holding
samples from normal distribution. Both a and b hold nan, c not. As you can
see in the attached screenshot only the boxplot for c looks ok.In [145]: matplotlib.__version__
Out[145]: '1.1.0'In [146]: np.__version__
Out[146]: '1.6.1'In [147]: a = [np.random.randn() if i % 5 == 0 else np.NaN for i in
range(1000)]In [148]: b = [np.random.randn() if i < 500 else np.NaN for i in
range(1000)]In [149]: c = np.random.randn(1000)
In [150]: d = boxplot([a, b, c])
In [151]: d['medians'][0].get_data()
Out[151]: (array([ 0.85, 1.15]), array([ nan, nan]))In [152]: d['medians'][1].get_data()
Out[152]: (array([ 1.85, 2.15]), array([ nan, nan]))In [153]: d['medians'][2].get_data()
Out[153]: (array([ 2.85, 3.15]), array([ 0.01285423, 0.01285423]))Wouter
