Hi,
please consider this snippet:
import matplotlib.pyplot as plt
d={}
for i in range(1,21):
d[i] = i**2
plt.plot(d.values())
plt.xticks(d.keys())
plt.show()
As it can be seen from attached screenshot, xticks values are shifted to
right (by 1).
Seems strange, but perhaps something to do wit
Thanks for your fast replies.
One more thing if possible: How can I tell xticks() to start at 0 (at x-axis
start)

Hm.. it not within matplotlib.pyplot module... needs more digging
OK, thanks

Yes, I noticed the same and indeed I used sorted values in original problem
I forgot to add it in my simplified snippet

I want to plot multiple plot lines, and would prefer lines to start at
x-axis beginning (so they "source" vertically from y-axis)
If I use suggested method from current replies lines would not start
from x-axis beginning, but I guess I'll need to look in Axes module
and make my preferences.
Thanks
Yes, that seems the right way
I used it before but forgot it in the mean time

I want to use kaiser window that's part of numpy for drawing spectrogram
specgram(x, NFFT=256, Fs=2, Fc=0, detrend=mlab.detrend_none,
window=mlab.window_hanning, noverlap=128,

scale_by_freq=None, **kwargs)

Ah, I was using wrong parameter... Thanks. That works fine

Thank you very much Fabrice
I have no further questions

Please consider:
plot([1, 2, 3, 4], label='line 1')
twinx()
plot([11, 12, 11, 14], label='line 2')
legend()
will draw only label for 'line 2'
plot([1, 2, 3, 4], label='line 1')
legend()
twinx()
plot([11, 12, 11, 14], label='line 2')
legend()
same result, as it will overwrite label 'line 1' wi
IMHO, when looking for basics and even more with intent to replicate some
graph, it's easy to start by looking at matplotlib gallery:
http://matplotlib.sourceforge.net/gallery.html and find best match.
In you case:
http://matplotlib.sourceforge.net/examples/pylab_examples/histogram_demo_extended.h
0 to 1 values not referenced to any plot.

Thanks JJ,
`axes_grid1` seems to handle this issue

Hi,
How can I use font in my locale or even better UTF-8 for plot
annotations?
Right now I can see only empty rectangles instead characters when I try
to enter anything other then ASCII
Thanks

Take any for example, like 'plot([1,2,3])' it doesn't matter
