Re: [Matplotlib-users] filled step plot?
Hi, Le 27/01/2013 00:35, Skipper Seabold a écrit : This has been asked before, and I just filed a ticket [1]. Can anyone think of a better way to do something like this? The fill_between below is pretty suboptimal IMO. I feel that adding a filled step plot would indeed be useful. Just thinking at a possible API, would it make sense to add the drawstyle argument which already exists for plot() to fill_between() ? best, Pierre signature.asc Description: OpenPGP digital signature -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

[Matplotlib-users] Problems installing matplotlib - compiling error
Hi guy, as I'm new to matplotlib I tried to install it following the instructions on http://matplotlib.org/faq/installing_faq.html#source-install-from-git http://matplotlib.org/faq/installing_faq.html#source-install-from-git .

Re: [Matplotlib-users] Baseline of TeX fonts
I guess you have text.usetex=True? In this case, the baselines are not correct unless you also set text.latex.preview as True. For example, try to add following line in your rc file. text.latex.preview : True (You also need preview.sty installed) If this does not solve the problem, please post a screenshot that demonstrating the problem with your rc file.

The points plotted on the map, corresponding to three different paths with a
line connecting all points. Mi final idea is to draw a line connecting the
points associated with each path, How I can do this? or How should I structure
my data to plot the different paths?
is posible draw an identifier or a mark for each path?
how I can set the size of the figure so that it can distinguish the separation
between the points?
