My poppler/xpdf installation should be allright

Summary:
matplotlib-0.87.3 with xpdf renders empty PS
upraded to matplotlib-0.87-3/numpy-0.9.8.
When setting ps.usedistiller to xpdf, I get an empty (blank) ps image.
Without xpdf, I get a proper ps. This did work with 0.87-2/numpy-0.9.6
(The Pdf backend works, but not with mathttext.)
Please set your verbose level to debug-annoying in your rc settings and
post the output. Also post your platform info, along with version info
for xpdf, and ghostscript. I havent had any problems with xpdf.

Re: [Matplotlib-users] Latex problems...
This is a known bug in ESP Ghostscript, not matplotlib. ESP version 8.15.02
broke xpdf's pdftops program. I posted a bug report to the ESP website, and
it has been fixed in their sources, but they havent made a new release since
that time. Your options are either to drop back to ESP version 7.07 or use
gpl or afpl ghostscript.

[Matplotlib-users] Colorbar
I'm trying to draw a contour plot in a Tk gui with an accompanying colorbar. The gui allows changing which contour is drawn. Some of the contours use a different set of levels, so I'd like to update the colorbar whenever the levels change. I don't need an automatic update -- what I'd like is to manually specify a new set of tick locations. What is the best way to do that?

John Hunter wrote: Christopher == Christopher Barker [EMAIL PROTECTED] writes: Christopher Just as a note, if you have Cairo, you have PS, PDF, Christopher SVG, raster, and, indeed, native draw-to-the-screen Christopher functionality. Last I checked if I recall correctly, about a year ago, the PS backend merely dumped a raster image and didn't do real vector graphics. Has this changed? There has been a LOT of work on Cairo in the last year, including the PS back-end. I'm just a lurker at this point, so I don't know how robust it is, but it supports vector operations for at least the common stuff. Here's part of a note posted in April to the mailing list: Is the output using image fallbacks in a case where you think it shouldn't, (that is, your drawing doesn't have any fancy translucence or something else that PostScript can't support natively). In particular, I want to know if cairo is now using fallbacks for something that was handled natively by the cairo 1.0 series. Which implies to me that it's working, and getting better. My main thought about Cairo is that there is little point in duplicating the effort that the Cairo devs are doing, even if it doesn't support a feature or two that is needed. It's better to contribute to Cairo. That is, unless, you are allergic to C (which I am mildly) or you have good reason to think that the whole framework of Cairo is inadequate. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/ORR/HAZMAT (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] - Using Tomcat but need to do more?

[Matplotlib-users] Improved dashing for black and white plots?
Hi all,
this is somewhat of a half-feature request, half-question. I just
went through a rather unpleasant exercise in trying to get a line plot
with about 8 traces generated for black and white printing. As it
turns out, mpl seems to only have 4 line styles ('-', '--', '-.',
':'), which isn't really a whole lot (compare this to gnuplot's
extensive dashing support). One can combine dashing with markers, but
the results aren't really very pretty (the relationship in spacing
between the dashing and the markers causes this, since the markers are
right at the data points while the dashing is whatever it is).
Mpl's color support is outstanding, but I need these figures in b/w
for a paper that will have no color figures, and I'm wondering what
others have resorted to in similar situations.
Additionally, I'd like to suggest having a b/w mode, where mpl's
auto-selection of different colors for successive line plots becomes a
rotation of dashing modes. Gnuplot's EPS backend has exactly this
feature, and it's absolutely fantastic: if color is on, it
auto-selects amongst many colors, but if color is off, it
automatically switches to contrasting dashing modes. This more or
less ensures that you can get the same plot made, either in color or
b/w, with nearly zero effort and still have distinguishable traces.
It's really nice to be able to generate a color version of the figures
for a talk and a b/w one for a paper, without hours of manual tweaks.
Anyway, I hacked an ugly-but-functional solution on my own, so this
message is mostly to put the issue on the radar, though I /am/
interested in solutions others may have.
Cheers,
f

Are you aware of the dashes property, which allows you to set the
exact dash pattern you want. It's an arbitrary length sequence of
alternating ink-on, ink-off, in points
# 5 points on, 2 off, 10 on, 5 off)
plot(arange(20), '--', dashes=[5,2,10,5])

Fernando modes. Gnuplot's EPS backend has exactly this feature,
This seems like a good idea -- if you define a nice sequence of dashes
you want to cycle through, I'll build the rest of the infrastructure
and make a figure property like iscolor.

Hi Darren,
Hmm, that didn't do it. Simple plots (like simple_plot.py) work with no
distiller step, so it must be something about my more complex plot.
Unfortunately, it's a rather complex menagerie of code that produces the
plot so I'm afraid that if I want to narrow this down, it'll be rather
painful and slow going. I might just stick with the
MPL-EPS-Distiller-PDF-Illustrator toolchain, which seems to work for
the moment.
