The plt.legend docstring says
To make a legend for a list of lines and labels::
legend( (line1, line2, line3), ('label1', 'label2', 'label3') )
So I would try something along the lines of
# plot lines
line1 = ax.plot(...)
...
linen = ax.plot(...)
lineleg = ax.legend((line1, ..., linen), ('linelabel1', ...))
# plot symbols
symb1 = ax.plot(...)
...
symbn = ax.plot(...)
symbleg = ax.legend((symb1, ..., symbn), ('symblabel1', ...))
Cheers,
Andreas

[Matplotlib-users] completely filling a figure canvas
I need some help in saving effort to make a figure fill its canvas: Is there a way to have subplots_adjust() automatically chose left, right, bottom, top values so that everything that's been drawn tightly fits the figure? Basically I'm looking for something similar to bbox_inclues='tight' in savefig, except that I want the figure dimensions to stay the same and have the contents of the figure adjust to the figsize so that no space is wasted. Obviously, the hspace and wspace in subplots_adjust would still have to be choseable by the user.

[Matplotlib-users] Question about basic_example_writer.py
Hi, when running basic_example_writer.py, I get *.mp4 files with a canvas size of 800x600 pixels (at least that's what mplayer tells me). However, I have trouble understanding where this canvas size comes from. The example does not explicitly set the dpi or the figure size, and I don't have a matplotlibrc which changes these settings. So figure.dpi is 80, and the fig.size_inches is (8, 6). So how come this translates to a 800x600 pixel movie?

[Matplotlib-users] Vertical alignment of AnchoredTexts in ImageGrid
Hi,
I'm cross-posting a question I asked on SO:
http://stackoverflow.com/q/15681890/152439
How can I vertically align text in matplotlib? My situation is as follows:
I'm using `ImageGrid`, to plot a row of five images:
grid = ImageGrid(fig,
rect=(0.06, 0., 0.885, 1.),
nrows_ncols = (1, 5),
direction="row",
axes_pad = 0.,
add_all=True,
label_mode = "L",
share_all = True,
cbar_location="right",
cbar_mode="single",
cbar_size="10%",
cbar_pad="0%",
)
Within each axes, I want to add some text. For this, I defined the
following function (following one of the examples):
def add_inner_title(ax, title, loc, props):
from matplotlib.offsetbox import AnchoredText
at = AnchoredText(title, loc=loc, prop=props,
pad=0., borderpad=0.5,
frameon=False)
ax.add_artist(at)
return at
which I use like this:
ax = grid[i]
tit = add_inner_title(ax, title, loc=3,
props={'size':'x-small',
'color':'#b0b0b0',
'weight' : 'bold',
'va' : 'baseline'})
Now, in one of the plots, the axes, the title is "Pollution Signal", in
another, it is "one", and in another, it is "GOME" (all just examples).
The problem is that now the texts are not vertically aligned: The
baseline of the text with a *g* is higher to accomodate for the needed
space below the baseline.
How can I achieve that in my case, all texts are vertically aligned,
given that the heights of the individual text boxes are different?
Any help is greatly appreciated!
Andreas

Thanks for your help, guys! I wasn't totally happy with the 'tight'
bounding box, as the margins to the legend were not uniform on all four
sides. So I did indeed return to a subprocess.call(['pdfcrop', ...]).

[Matplotlib-users] Placing a 'title' inside a legend
Hi, I'd like to place something like a 'title' inside a legend's box. In my specific case, I have a legend with 5 entries, arranged in 5 columns, so they're horizontally next to each other in one row. Now what I'd like to have is inside the legend's box a first row (above the legend entries), where I can write some text. Any ideas?

You could use numpy.genfromtxt together with its `converters` parameter:
converters : variable, optional
The set of functions that convert the data of a column to a value.
The converters can also be used to provide a default value
for missing data: ``converters = {3: lambda s: float(s or 0)}``.
Cheers,
A.

[Matplotlib-users] hist() and masked_array
Hi there, I just noticed today that when I call hist() on a masked_array, also those values which are masked out are displayed (with their fill_value). Is that really the desired behaviour? I'm working in an environment where we're mostly using masked_array, but also sometimes the 'normal' ndarray. So I would need to do something like try: data = data.compressed() except: pass hist(data) all the time ... Is there any easier solution?

[Matplotlib-users] Setting boundaries for a colorbar
Hello there,
using matplotlib 0.99, I have a problem with colorbars, which is illustrated
by the following code:
---8<---
from matplotlib import ticker
import numpy as np
a = np.arange(676).reshape((26,26))
x = y = np.arange(26)
colorMap = mpl.cm.get_cmap('jet', 10)
colorNorm = mpl.colors.Normalize(vmin=0, vmax=400,clip=True)
plot = contourf(x,y,a,10,cmap=colorMap,norm=colorNorm, \
locator=ticker.LinearLocator(10))
cb = colorbar(plot,orientation='horizontal',cmap=colorMap,norm=colorNorm, \
extend='neither',spacing='uniform')
---8<---
So I have data ranging from 0 up to say 675. I want to create a contour plot,
but the colorbar should only go up to 400, and all values higher than that
should be shown in the color of the maximum value 400, which is working
fine.
However, the colorbar does not go from 0 to 400, but rather from 0 to 675:
---8<---
In [52]: cb._boundaries
Out[52]:
array([ -6.7500e-04, 7.5000e+01, 1.5000e+02,
2.2500e+02, 3.e+02, 3.7500e+02,
4.5000e+02, 5.2500e+02, 6.e+02,
6.75000675e+02])
---8<---
The colors shown are correct, but the colorbar looks ugly, because two
thirds
of it are filled with the color of the maximum value.
According to the documentation
(http://matplotlib.sourceforge.net/api/colors_api.html#matplotlib.colors.Normalize):
If clip is True and the given value falls outside the range, the
returned
value will be 0 or 1, whichever is closer.
So my question is: What do I need to do so that the colorbar actually has
the
range as specified by my colorNorm?
Thanks for your help,
Andreas.
