It depends on what you mean by lack of a license. I think what most people (myself included) would like to see for a demo script is this file is in the public domain. That is not exactly a license, but it roughly means use this however you want without worrying about any restrictions, not even attribution requirements. I do not think the LGPL generally makes sense (literally) for such scripts: http://www.gnu.org/licenses/lgpl.html If public domain is uncomfortable, then perhaps MIT or BSD would be comfortable. URL:http://www.opensource.org/licenses/mit-license.html Of course, s/he who has the copyright chooses the license. Cheers, Alan Isaac Although we're markedly off-topic here, I want to mention that I've battled with the question of licensing my code. It's documented here: http://eli.thegreenplace.net/2006/04/13/choosing-an-open-source-license-for-my-code/ The choice of LGPL eventually stems from my desire to promote free software, and prevent abuse. True, for demos it makes less sense than for full-blown libraries, but still... Consider this: the demo teaches someone how to make some interface/code work. He got it for free, because I've placed my demo publicly online. But he may want to incorporate it in his program, and hide from his users how he does the thing the demo taught him, winning a competitive advantage. This isn't fair, and LGPL prevents such use, while in general allowing one to use the code in commercial applications. My understanding of what can and cannot be licensed, at least in U.S. law and (as far as I know) some other areas as well, is that what you are trying to guard is something you cannot guard unless you get a patent. The specific text of a program, its concrete form, and perhaps other concrete implementation features are covered (or at least can be covered) by copyright. Knowledge, including how he does the thing the demo taught him, is not subject to copyright. That is, if he legally reads your code, and clones functionality, there is no way barring a software patent that you can restrict this. I personally regard viral licenses with caution: that is, if the copyright says, Don't build on or extend this unless you want your work to be covered by my chosen license, I will be extremely cautious about building off of them. Under the LGPV, if I incorporate one of your demos into my own 2000 line program, your requirements of fairness require me to place my entire 2000 line program under the terms of the license you chose. This is a significant deterrent to some programmers.

Re: [Matplotlib-users] Crash on import with CGI wrapped by PHP--unhappy with .matplotlib directory?
I found a reason for the behavior: The script was running as user apache, but trying to open /root/.matplotlib, and /root was mode 0700. It stopped crashing on import after I made /root mode 0711. This is somewhat surprising behavior to me; shouldn't it be defaulting to something besides expected access to ~root?

Re: [Matplotlib-users] Border appearance
Taking a step back:
What should I be digging into so I'll have the concepts and tools to
manipulate features like color and thickness of borders on a bar chart and
on a pie graph and any parts that may have a border, whether the shadow on a
pie graph is on the lower left or upper right, etc.?
I'm looking at the
tutorialhttp://matplotlib.sourceforge.net/tutorial.html; I'd welcome
suggestions or clarifications about what I should be reading.

There are two borders in question, the figure border and the axes
border. Both are rectangle instances. You can control the figure
border with the figurePatch instance
fig.figurePatch.set_edgecolor('white')
fig.figurePatch.set_linewidth(0.5)
and similarly for the axes axesFrame instance
ax = axes([left, bottom, width, height])
ax.axesFrame.set_edgecolor('red')
ax.axesFrame.set_linewidth(0.5)
You can make the frame invisible in a few different ways:
* set the edgecolor to be the same as the face color
* set the linewidth to 0
* set the visible property to False (ax.axesFrame.set_visible(False))

You can make the tick lines invisible like so for line in ax.get_xticklines() + ax.get_yticklines(): line.set_visible(False) This is presuming you want ticklabels but not lines.

I was specifying the axes earlier, and setting a linewidth of 0 seemed to
remove one of two borders (or, from a non-technical perspective, made the
border half as thick). See before.png and after.png: getting closer at

[Matplotlib-users] *Non-interactive* image generation?
I would like to use pylab in a CGI script that would generate a pie chart/bar graph/..., save it to a file, and then be able to output the image from the file. Everything that I've tried works if I run the script from my shell, but when it runs on my test box (or, for that matter, a sudo without an X display being set up), it gripes about not being able to open an X display. Is there a way to either: 1: Tell pylab to run without a display, 2: Configure a dummy display, or 3: Attach the web environment to a real display?
