That means you are trying to call TeX, which is not supported by that
version of the pdf backend.

usetex=True means that you are trying to use an external TeX program.

Re: [Matplotlib-users] creating a timeline
I think I have something I like reasonably well. Is that attached
timeline fairly intuitive? I am proposing a project for next summer
that has two main parts. Each part has three subsections that are
roughly one month long.
Thanks,
Ryan

Re: [Matplotlib-users] creating a timeline
I am really just getting to mess with this now and ran into an issue.
I want to turn off the y axis and 3 sides of the border around the
plot area, so that I left with just the bottom x-axis and its tick
marks. Turning off the y axis is easy enough, but the only way I
found to get rid of the border is with
ax.set_frame_on(False)
which also gets rid of my bottom x axis and leaves tick marks along
the top (see attached). How do I get rid of the top tick marks, keep
the bottom ones, and get the bottom x-axis back?
Thanks,
Ryan

No, it's much simpler: in matplotlibrc there is a setting for "lines.solid_capstyle", and apparently the default is "projecting", but you want "butt". -- Jouni K.

I apologize for the missing information. I was using matplotlib 0.90.0
with python 2.4, and just upgraded to matplotlib 0.90.1 after reading
your message. Also, I'm doing this all on winXP.
Now, when I try to save a PDF (with the newer version of matplotlib), I
get the error:

I guess I mean TeX-like mathtext format parsed by matplotlib. For
example, I'm using things like this:
rc('text', usetex=True)
Plotting.xlabel(r'\textbf{Time (s)}', fontsize=16)

I meant that you could read through collections.py and implement a CircleCollection along the lines of the other collections there. I'm not quite sure what exactly this entails [so I'm not expert enough to answer your question :-)]. At least it would mean a new method for backends, although one that you could implement once in backend_bases. (Now that I look at collections.py, the base class Collection has a get_verts method that derived classes should override and that other parts of matplotlib call, so perhaps collections of non-polygons would require more extensive changes than just adding a new subclass.) The advantage would be speed of rendering in case you draw lots of circles, so if speed is not a problem, don't worry about this. -- Jouni K.

[Matplotlib-users] latex labels on saved plots
Hello, I'm having trouble saving eps or pdf versions of plots that have TeX labels using matplotlib. When I try to save an EPS file, I get the message: ... RuntimeError: ghostscript was not able to process your image. Here is the full report generated by ghostscript: (Author's note: No 'report' is actually printed) When I try to save a PDF file, I get the message: ... File "C:\Python24\Lib\site-packages\matplotlib\backends\backend_pdf.py", line 1085, in get_canvas_ width_height return d*self.file.width, d*self.file.height AttributeError: PdfFile instance has no attribute 'width' Does anyone have any suggestions for how to fix this? The TeX labels work fine is I save as a PNG file. I saw an older thread (http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg03953.html ) that seems to address similar issues, but I don't understand the solution (using XPDF distiller).

[Matplotlib-users] Screen location
Hi all! I'm actually working with Matplotlib/Pylab Interface for making 2D plot. I need to specify screen location where the frame will appear and I don't know how. Supose a simple example like: from pylab import * t = arange(0.0,10,0.01) s = 20*sin(2*pi*t) c = 20*cos(2*pi*t) figure(1) plot(s) figure(2) plot(c) show() If I do it in this way, one frame is hidded behind the other one. How can I modify frames attributes in order to change their position on the screen? Thanks in advance, Miquel - This SF.net email is sponsored by: Microsoft Defy all challenges.

bling-bling. I know it is eye candy and in questionable taste, but I
think it fits my non-technical audience in this case. I think this is

See examples/broken_barh.py (this also allows breaks in the horizontal
bars, eg if an event is interrupted and then resumes). I haven't
added gradient fills on bars because I don't think they convey little

"chart junk" to use Tufte's phrase) but at some point we should bow to
popular pressure and add it. Actually, you can hack gradient filled

[Matplotlib-users] creating a timeline
I would need to create a timeline for a Latex document (eps output). There may be other tools besides Matplotlib and I am open to suggestions. But I were going to use mpl, what would it take to do something along these lines: http://www.timelinemaker.com/product-samplecharts-constructiontimeline.html Basically, I would need a nicely formatted dates along the x-axis and then lightly colored rectangles with text in them. The width would show when I anticipate some part of the project starting and ending. The y coordinate of the rectangle would used to allow project portions to overlap. It would be nice but not essential if the rectangles had a little fade in and out in their back ground color instead of a solid color, but that is not essential. Is there a clean way to do this with mpl? Thanks, Ryan - This SF.net email is sponsored by: Microsoft Defy all challenges.

With GDAL, it's trivial. I work with data from many sources, and I am usually bypassing basemap altogether and going GDAL/OGR+MPL. To show the first band of a raster map, I just do the following: import pylab import gdal fname="/path/to/file" g = gdal.Open ( fname) data = g.GetRasterBand(1).ReadAsArray() #data is a Numeric/numpy array.

Re: [Matplotlib-users] Drawing filled circles (discs)
In the solution I gave, CirclePolygon has a resolution argument for
number of vertices to approximate the circle (default=20). You could
increase that value to some more appropriate level:
import matplotlib
from matplotlib.patches import CirclePolygon
from matplotlib.collections import PolyCollection
import pylab
fig=pylab.figure()
ax=fig.add_subplot(111)
resolution = 50 # the number of vertices
N = 20
x = pylab.rand(N)
y = pylab.rand(N)
radii = 0.1*pylab.rand(N)
colors = 100*pylab.rand(N)
verts = []
for x1,y1,r in zip(x, y, radii):
circle = CirclePolygon((x1,y1), r, resolution)
verts.append(circle.get_verts())
p = PolyCollection(verts, cmap=matplotlib.cm.jet)
p.set_array(pylab.array(colors))
ax.add_patch(p)
pylab.colorbar(p)
ax.axis('equal')
pylab.show()

Hi all!
Thank you very much indeed for the help, both solutions work like a
charm.
However Dave's one gives rough cirlces, approximated by polygones, which
is not very accurate for my buisness. May I ask how to create a
circleCollection as Jouni "The Expert" proposed?
You can find below one of my plottings rendered by Jouni's first trick.

If you can figure out how to read a geotiff (I've never tried it, but GDAL should be able to do it), you should be able to use the projection information in the file to figure out the lat/lon values of each pixel. Then you could follow the warpimage.py example to transform it to some other map projection. Or, if you want to display it in it's native projection, just use the projection information in the geotiff to define a Basemap instance, extract the rgba values and plot them with Basemap.imshow. -Jeff -- Jeffrey S.
