I'm trying to do an animation which plots a large number of items on
two dimensions, and then animates their positions over time. I have
set up the plot with my dimensions on the axes and am using
canvas.blit (as shown in one of the examples) to update my plot. I'm
using text as the

Hi Che,
I think turning off autoscaling is what you need:
import matplotlib.pyplot as plt
ax = plt.subplot(111, autoscaley_on=False, ylim=(0, 100))
plt.plot([1, 2], [-40, 40])
plt.show()
Kind regards,

Hi all,
How can I combine onpick events with annotate ?
Any pointer would be appreciated.

fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_title('click on points')
line, = ax.plot(np.random.rand(100), 'o', picker=5) # 5

Thanks for all your suggestions Christoph. Launching the Tk Python Shell
instead of PythonWin seems to work consistently - I get the correct plot
figure and the correct log_plot.png file created everytime I run the
script. I never did install Ipython, but I'll consider that for a future

Hi List,
I made a script to draw very simple (single-direction single-input
single-sided single-everything) Sankey diagrams (attached). I think I could

Great -- I had never heard of a Sankey diagram but just
Hi,
following my own post, I attach an upgraded version of the sankey.py script to
draw single-direction Sankey diagrams. It now supports multiple inputs and
double-sided diagrams (see attached example). Let me know if you find it
useful, and/or have any comment.

Hi,
I am a beginner with matplotlib.
I am trying to analyze huge dataset, the plot would have multiple lines. I
am getting memory error (it fails maxing out ~2.5GB on my system). I am
assuming there are probably ways to simplify the data, I came across
something 'simplify' for 'path', not sure

This is probably a silly question based on my bias from matlab, but I have

Jeff,
I send all of my figures through LaTeX and don't have this problem. The only
thing I can think of is to check your matplotlibrc file and make sure you've
set the legend font to be the same size as the other fonts.

Hello Krishna,
This is really crazy ploting so many data point, after all the human
eye can't separate all the data.
Try sampling the vector of the data point - to a smaller extent.
Here's a quick and dirty solution how to sample every nth element in a
vector - there's probably a faster way,

Ah, I didn't know there was a section of the rc file for legends. Adding
mpl.rcParams['font.family'] = 'serif'
mpl.rcParams['legend.fontsize'] = 'medium'
fixed things right up.

Following up on Oz's point ...
let's suppose that is 5M points for each of the 6 lines,
and that you will try to place them on a 5 inch wide axis.
That is
Really cool plot.
Speaking of the 1.0 release, is there a target date set? And if there is going
to be another bug-fix release before 1.0, is there a target date for that?

I am wondering how to animate using blit and patches.
The code below was modified from one of the examples.
You will see that it shows (and moves) the rectangle just fine, but
the circle never shows up.

grid takes an optional argument which. Unfortunately this is not
properly documented with pylab.grid and Axes.grid.
But see
