I wish I could say that it was because of a deep understanding of the inner

Indeed, it works also for me with Python 3.3.5.
Could you explain the changes you made and the reasons behind the
byte/string encoding ?

Many Thanks for your support.
It is Python 3.3.5 and matplotlib 1.4.0
I've also found that it worked with ByteIO(), but then I was stuck by the
encode/decode things. Thanks very much !
The traceback is below:
Traceback (most recent call last):
File "", line 1, in
runfile('/home/hash/exa
This works for me with python 3.4.2
import matplotlib.pyplot as plt
from io import BytesIO
import base64
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot([1,2,3])
sio = BytesIO()
fig.savefig(sio, format="png")
html = """
""".format(base64.encodebytes(sio.getvalue()).decode())
For python
Please post the entire traceback so that we can know the context of the
error message. Also, exactly which versions of matplotlib and python are
you using?

Dear all,

However, the following piece of code does not work with matplotlib/Python3

I would also like to point out that you can specify "auto" for a location,
and matplotlib will attempt to find a good location for you (within the
plot area). It isn't perfect, but it can be useful.

Hi Peter,
just get the legend handlers and labels with
handles,labels = ax.get_legend_handles_labels()
then create an empty plot with axes `axe` and do
axe.legend(handles, labels, loc=loc)
If you want to hide the axis:
axe.xaxis.set_visible(False)
axe.yaxis.set_visible(False)
I would like to ask if there is a way to print only the legend box of a figure.
The motiviation for wanting to do this is a work around to the problem of
having the legend box obscuring data without resorting to "outside" placement
of the legend. The idea here is that matplotlib would pr

Hi all,
I've noticed that savefig is very slow when I draw wind (using "quiver" and
"quiverkey" commands).
If I don't draw winds is very fast (2 seconds against 13 seconds).
Is possible to make the program faster? Any idea?
I use the 'Agg' backend and the latest version of matplotlib.

It has no way of deducing the file format from the file object.
You need to explicitly pass the format keyword to savefig, e.g.:

Hello,
I am getting an error with savefig and pdf when I try to used matplotlib
with latex font rendering (attached below). In etc/matplotlibrc, I set
text.latex.preamble : \usepackage{MinionPro},
\renewcommand{\sfdefault}{Myriad-LF}
It seems that the dviread backend does not find a specific *.vf,

Hi mpl users,
I am trying to save a figure to a file like object (a StringIO object)
and load this object into PIL (Python Imaging Library). The code for
this is really simple (fig is my figure object):
# This works
fig.savefig('test.png', format='png')
im = Image.open('test.png')
# This fails

Hi
I have a script to plot and save a sequence of png images which I am using
to prepare animations. This works fine, but I got the following error when
preparing a particularly large number of files:
--- record: 1015
--- record: 1016

Hi,
I am trying to save figures where all the artists have animated =
True. The result I get (I have tried svg and png formats) is a set of
axes with labels, ticks, and grid, but no data points! I am using the
WxAgg backend.
Is this something to be expected, and if so, can anyone suggest a workar

Hi,
I am trying to use matplotlib to generate png image plots to display in web

Mike,
Updating to 0.91.1 fixed it. Python's memory usage was climbing in
excess of 1 GB when running this script before (eventually crashing) --
now it hovers nicely around 60MB and completes with no problems. Excellent!
Thanks,

You can try running the garbage collector after each savefig. ("import
gc" and then call "gc.collect()"). If you are using a GUI backend, you
may want to try using the "raw" Agg backend instead -- there are fewer
moving parts that way.
There have been a number of memory leaks that have been f
Hi all,
I've noticed that when I save my figures using savefig the memory is
not immediately released. For example, in pseudocode,
times = get_times()
for var_id in var_list:
Plotting.figure()
var_values = get_values(var_id)
pylab.plot(times, values)
Plotting.savefig(var+'.p
Hi -
I am writing a script that will generate many figures.
Currently this script lives in matlab and outputs these figures to a single .ps
file:
if( first )
print( nfig, '-dpsc2', '-r300', '-loose', filename );
else
print( nfig, '-dpsc2', '-r300', '-loose', '-append', filename );
end

Hi all,
I've got a problem with saving plots in pdf format like you can see in the
following output. It seems encodings.cp1252 doesn't have a decoding_map
method (but a decoding_table one).
Is it a bug or a problem in my encodings file?
thanks

Hi,
After a few trials and errors I could finally set up plots the way I wanted by
modifying the matplotlibrc resource. In an essence, I want bright information
(fonts,lines) on dark background (figure bg, axes bg) and I can fully achieve
this goal while DISPLAYING plots. However, SAVING damages
