John, I have no objections to the change you propose, and your idea of adding inheritance sounds good, also. Even nicer might be some flexibility in specifying units, so that a pad could scale with fontsize instead of being given in points, for example. My reservations about the rc file approach come partly from the concern that it can be too hidden, especially when the filename is prefixed with a dot--which, fortunately, we don't do. Still, a user might understandably wonder where the active configuration file really is, (hint to other readers: try the matplotlib function, matplotlib_fname()) and having a program behave differently depending on the current working directory when it is run is a double-edged sword. Style-file functionality is clearly a good thing, so the question is whether to make it explicit. One way to make it more explicit would be to invoke it via a script's command line, just as the backend can be specified via the command line. I don't know if it is worth adding this as an option, but it might facilitate testing, if nothing else. Potentially, the style-file parts of a matplotlibrc file could also be read in by a function at any point in a script. I was also unhappy with situations where the rc mechanism--which really should be used for global configuration--was the only mechanism available for local customization. I don't know whether there are still such cases, but the one that particularly bothered me--tick customization--can now be done without setting and resetting rc parameters. Enough idle rumination...

Of course this will affect any other patches in your figure (eg Rectangles from histogram plots, etc). I am not opposed to adding some legend.frame rc parameters. Part of the purpose of the rc file is to work like a style sheet, so if you are writing a book or an article with a bunch of figures, and you want them all the have the same look-and-feel, you can customize the defaults externally w/o a bunch of boilerplate in your scripts that can be difficult to maintain. It seems like the legend frame properties fit into this category. In particular, the frame alpha is one I almost always set to semi-transparent so you can see data behind the legend, which is boilerplate I might be happy to do away with if I had an rc param. I would be amenable to adding: legend.frame.facecolor : 'white' legend.frame.edgecolor : 'white' legend.frame.linewidth : 1.0 legend.frame.alpha : 1.0 but I'd like to hear from others (Eric?) who are already not happy with the size of our rc file. Although this change would increase the line count, it doesn't increase the complexity much if at all in my view and is somewhat useful. It would imply some mild potential breakage, because currently the legend face and edge colors use the axes colors (which is why it would be nice if we had containment/inheritance for our rc params so they could inherit from parent) so if someone has tweaked their old axes.facecolor, they would need to add legend.frame.facecolor under this change to remain compatible.

It seems that there are no rc settings for these, but you can adjust them as follows: > a.plot(x, y, '--', label='foo bar') Change this to a.plot(x, y, '--', label='foo bar', dashes=(2,2)) The value of dashes is the number of points of ink followed by the number of points of whitespace.

[Matplotlib-users] Scale legend box border, dashed and dotted lines when the figure size is changed
Hi,
I posted this to stackoverflow
(http://stackoverflow.com/questions/3190798/scale-legend-box-border-dashed-and-dotted-lines-when-the-figure-size-is-changed),
but didn't get any answer, so here goes again:
I'm trying to use matplotlib to prepare some figures for publication.
In order to make the font sizes match the text of the manuscript I'm
trying to create the figure in the final size to begin with, so that I
avoid scaling the figure when inserting it into the manuscript.
The problem I'm having is that as the figure is then pretty small, I
can scale font sizes, axis sizes, line widths etc., but what I've been
unable to figure out is how to scale dashed or dotted lines, as well
as the thickness of the legend border box. For a simplified and
somewhat exaggerated example, consider
#!/usr/bin/python
small = True
from matplotlib import use
use('pdf')
from matplotlib import rc
rc('ps', usedistiller='xpdf')
rc('text', usetex=True)
if small:
figsize = (1.0, 0.5)
rc('font', size=2)
rc('axes', labelsize=2, linewidth=0.2)
rc('legend', fontsize=2, handlelength=10)
rc('xtick', labelsize=2)
rc('ytick', labelsize=2)
rc('lines', lw=0.2, mew=0.2)
rc('grid', linewidth=0.2)
else:
figsize = (8,8)
import numpy as np
x = np.arange(0, 10, 0.001)
y = np.sin(x)
import matplotlib.pyplot as plt
f = plt.figure(figsize=figsize)
a = f.add_subplot(111)
a.plot(x, y, '--', label='foo bar')
a.legend()
f.savefig('mplt.pdf')
If you change the first executable line to small = False you can see
how it should look in "normal" size. Compared to the normal size, the
small plot suffers from a legend box with too thick borders, and the
dashed line is too coarse, i.e. too long dashes and too long distance
between the dashes.
So my question is, is there a way to fix these two problems?
The matplotlib version I'm using is 0.99.1.2 on ubuntu 10.04 amd64.
