To matplotlib-users,
When I do:
cd basemap-1.0.7/examples
python3 simpletest.py
Then I get this error message:
Traceback (most recent call last):
File
"/usr/local/lib/python3.4/dist-packages/matplotlib-1.3.1-py3.4-linux-i686.egg/matplotlib/backends/backend_gtk3cairo.py",
line 32, in on_draw_ev
Thank you for the help!

Yes. I am multipliying the width of the bins by their total height.
Surely there are cleaner and more general ways

That worked beautifully thank you!
Am I reading (bins[1]-bins[0]) correctly as taking the difference between
what is in the second and first bin?

I guess it is showing, but you have many data points, so the gaussian
is too small down there. You have to increase its values to make both
areas fit:
plt.plot(bins, N*(bins[1]-bins[0])*y, 'r--', linewidth=1)
And you will get a nice gaussian fitting your data.

Thanks for catching that sigma was still a vector! I am no longer getting the
errors, but the best fit line is not showing up.Is there something else I am
missing ?
BTW thanks for the heads up on the np.mean and np.standard functions.

You should not change bins there, as you are evaluating the gaussian
function at different values.
Also, sigma is a vector, but it should be an scal
Just tried it with nbins set to 216 and I still get the error

Hi David,
I tried your fix
nbins = 20
n, bins, patches = plt.hist(C, nbins, range=None, normed=False,
weights=None, cumulative=False, bottom=None, histtype='bar', align='mid',
orientation='vertical', rwidth=None, log = False, color=None, label=None)
plt.title("")
plt.text(25,20,'M < -21.5' '\
In the example you provide, bins is returned by the hist command,
whereas in your code, bins is a number that you defined as 20. So,
change:
bins = 20
plt.hist(C, bins, ...
by:
nbins = 20
n, bins, patches = plt.hist(C, nbins, ...
As a side comment, your data loading is too complex, and fail pr

Hello,
I keep getting the error "ValueError: Need more than 1 value to unpack"
every time I try to use the line ax.plot_wireframe(myArray[:,0],
myArray[:,1], myArray[:,2])
What does that error mean?
Thanks,

Hi List
I cannot figure out how to satisfy this issue to resolve the ValueError:
x and y must have same first dimension.
This is the relevant code:
[code]
for i in range( 0, time + 1 ):
outflow = constant * quantity
quantityChange = inflow - outflow

Thanks for all replies.
I got a solution by copying some files from SVN trunk revision 6155. I did
as follow:
svn co
https://matplotlib.svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib
sudo cp
-b matplotlib/lib/matplotlib/backends/backend_pdf.py

Are you perhaps trying to plot data containing NaN or Inf? If so, this
is a known bug in 0.98.3 that has seen been corrected on SVN trunk.
A workaround is to pass masked arrays (where the NaNs and Infs are
masked out) to matplotlib instead.
But this bug should be gone in the next release of ma
Dear all,
I don't know much how to express this issue I am having but I will try.
We are developing an application (CING: cing.googlecodes.com) and we
have some routines to test the sanity of our code.
I am developing in python, on a mac book pro with Mac OSX tiger and FINK.
So when we were usi
Can you provide a standalone script to illustrate this problem?
I suspect that the position of the text is somehow negative and is getting
masked away by the log transformation (which is obviously undefined for
negative numbers).
Also, have you tried the GtkAgg backend instead? That sees a lot

Sorry should have done that, I've attached an example script (and the
according data files) which exhibits the problem on 0.

Sorry if it hasn't helped.

Hi
Just upgraded to matplotlib-0.98.1, and a code that worked with 0.98.0
is now failing with the following error:
