Re: [Matplotlib-users] add an arrow to a lineEnd
Hello, I want do add an arrow *tip* to a line with the same angle. I have tried this: from pylab import * from matplotlib import collections, transforms def MyArrow(ax, x, y, ang, scale=50, over=.5, color='k'): ar = [(0,0), (-.5,-over), (0,1), (.5,-over), (0,0)] col = collections.PolyCollection( [ar], offsets=(x, y), transOffset=ax.transData, color=color ) col.set_transform(transforms.Affine2D().rotate(ang).scale(scale)) ax.add_collection(col) plot([0,1,2], '.-', lw=2) MyArrow(gca(), .5, .5, -pi/4) draw() and I get an arrow tip without the same line angle :-( See the attached image. Can you help me to get the right transformation? Thanks, Friedrich <>- This SF.net email is sponsored by: Microsoft Defy all challenges.

[Matplotlib-users] position of ylabel
Hello,
I want to adjust the x position of my ylabel, like
subplot(111)
ylabel('YLabel', x=-.25, y=.75)
the 'y=.75' argument is applied but the 'x=-.2' argument has no affect.
But why? Have you any idea to do this?
Thank you,
Friedrich

Oh, thank you very much. The
gca().yaxis.set_label_coords(x, y)
command works fine for me :-)
But one qusetion. I think the user interface
ylabel('yLabel', xpos, ypos)
would be better. So I would do somethink like this in ylabel()
if xpos is not None:
self.set_label_coords(xpos, ypos)
What do you think?
Many thanks,
Friedrich

[Matplotlib-users] Python Distribution with matplotlib
Hello, today I tried to install mpl in my local home directory at work. This debian distribution is very old and I had to compile for my own. But I failed to compile pygtk (special cairo and pango) as a dependency for mpl. So I have two questions: 1. Does you have an advice to compile mpl with minimal dependencies? 2. Does anybody know a good python dirstibution including mpl? Thanks, Friedrich - Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

Here is my (easy and maintainable) way to handle the versions for my graphics: * I write the data creation in a python script * I write the creation of the mpl graphics in a script (most the same) * I manage these python file with a version-system (eg mercurial) So I have different versions for my mpl graphics and I can modify the graphic any time (with a new python run). If the data creation takes too long, I could save the data in an extra file (eg pickle file) and versioning the pickled file. So I dont need an extra way to reedit a mpl graphic.

You could return the plotted lines from the function plotb.
Here is my attempt:
In [1]: x=arange(0,5)
In [2]: y=array([ 1.2, 3.4, 5.4, 2.3, 1.0])
In [3]: z=array([ 2.2, 0.7, 0.4, 1.3, 1.2])
In [4]: def plotb(x,y,col):
...: lines = bar(x,y,color=col)
...: return lines
...:
In [5]: l1 = plotb(x,y,'k')
In [6]: l2 = plotb(x+0.4,z,'y')
In [7]: legend((l1[0], l2[0]), ('YYY','ZZZ'))
Out[7]:
The legend() function could label any line object. So every single bar-line
could be listed in the legend. But I think you would only have one from
each color, so I have choosen the first: l1[0] and l2[0].
Is this what you what?

pgf is a tex-based graphic language similar to ps-tricks but also
for pdftex. There are very nice graphics:
http://www.ctan.org/get/graphics/pgf/base/doc/generic/pgf/pgfmanual.pdf
The basic drawing is like this (a cross)
\begin{tikzpicture}
\draw (-1.5,0) -- (1.5,0); % horizontal line
\draw (0,-1.5) -- (0,1.5); % vertical line
\draw (1,1) node{$y=x^2$}; % text label
\end{tikzpicture}
There also exsits makro pakages for (more ore less convinent) data plots
but then you dont have the nice python interface.

I want that fonts in the mpl graphics have the same (or otherwise related)
proerties as the main-font in my latex document.
So, therefore I have to know all the font properties from my latex
document (\normalfont): type, family, size.
The next problem is that the standard size of the mpl graphic (8, 6) inches
is too big for my latex document (0.5\linewidth). Therefore I must scale
the mpl graphic (\includegraphics[width=0.5\linewidth]{...}). But with this
scaling the font in the mpl graphic are also scaled and I have no chance
adapeting the two fonts (mpl, latex) without manual iterations.
Ok, I could adjust the figsize but the last time I did it (long time ago)
there were other misplaced objects in the mpl graphic (I dont remember
exactly, sorry).
But if I had the whole mpl graphic as pgf commands there would be no
problem with the font stuff, scaleing and line widths. And may be you
could extend the mpl graphic with some tricky (and eye candy) pgf
extensions (ok I am also a beginner with the pgf language but its
realy powerfull).
BTW. In the same way I can create very nice ciruit schematic with
CircuitMacros
www.ece.uwaterloo.ca/~aplevich/Circuit_macros/html/examples.pdf
I hope you could understand what I mean :-)

I tried this now with (width = 7cm = 2.67in)
In [1]: figure(figsize=(2.67,2))
Out[1]:
In [2]: subplot(111)
Out[2]:
and the problem is that the remaining (abolute) space of the margin
ist too small for the whole labeling (ticks and axis). But I dont
want to adjust all the default values every time a what a plot in
my latex document.

Shortly: Yes this is a problem but pgf could solve it.
I dont know it exactly but if you do all the graphic stuff with pgf in
latex so you can adjust the text boxes in a various way in respect to
different points. E.g. baseline -left, -right, -center and so on. This is
explaind in the pgfmanual in section 53.3.3.
If I fly over the pgfmanual I get the impression that I could do
everything with it :-) But to do this its a hard work (for beginners).
Therefore I like to have the convinient pylab-interface to create pretty
standard plots for latex.

[Matplotlib-users] ugly arrow with xpdf
Hello,
when I create an arrow with
>>> from pylab import *
>>> subplot(111)
>>> arrow(.5, .5, -.05, .02, lw=5, width=.01)
>>> savefig('foo.pdf')
and view it with
% xpdf foo.pdf
then I see on the startpoint an ugly pike. With gv and evince everything
is ok.
Any idea how to fix it in mpl? Because I dont want to switch to an other
viewer then xpdf.
Thanks,
Friedrich

[Matplotlib-users] add an arrow to a lineEnd
Hello, the original problem that I have is to add an arrow to the end of a plotted line. I tried this from pylab import * x=linspace(0, 1.85, 100) y=sin(x) dx=x[-1] - x[-2] dy=y[-1] - y[-2] plot(x,y,lw=2) arrow(x[-2], y[-2], dx, dy, width=.02, length_includes_head=True, head_length=sqrt(dx**2+dy**2), lw=0, overhang=.1) But this is ugly. And when I zoom in the arrowsize isnt scaled with the linewidth. Any idea instead to switch to the pyx package? By, Friedrich - This SF.net email is sponsored by: Microsoft Defy all challenges.
