[Matplotlib-users] newline in mathtex
Dear all, is it possible to insert newlines in mathtex text? neither \newline, nor \\ seem to be understood: In [20]: text(.5,.5, r'$This is the first line \\ this is the second line$') Results in a single line. By the way, when there is an error in the tex string, the caching behind the scenes seems to be broken: In [21]: text(.5,.5, r'$This is the first line \newline this is the second line$') . ValueError: unrecognized symbol \newline # removing the \newline command still yields the same ValueError In [23]: text(.5,.5, r'$This is the first line, this is the second line$') . ValueError: unrecognized symbol \newline Thanks!

[Matplotlib-users] simple question: how to set the gap between label and axis
Sorry to bother you guys, but I cannot figure out how to set the gap between the axis label and the axis. I know it can be done.

Re: [Matplotlib-users] SVG vs PNG
This SVG format gets better everyday. For those of you unfortunate enough not to have the choice of freedom from the M$ Monopoly, I discovered that Visio supports SVG file directly. In fact, the rendering is better then Inscape and get this: you can copy and paste *directly* over to PowerPoint and Word and you can even embed it as a Visio object. The quality is superb! Even the browser can read SVG file (somewhat - the quality isn't very good). -Original Message- From: Derek Hohls Sent: Tuesday, May 15, 2007 12:19 AM Subject: Re: [Matplotlib-users] SVG vs PNG For those of you fortunate enough to have the choice be free from the M$ Monopoly, you can use the Open Office Impress package to do something similar to the steps below. However, if you want to work directly with SVG files, then you should install the SVG import filter, available from: http://www.ipd.uka.de/~hauma/svg-import/ (Installation and use are described very clearly). If you have saved an SVG file from MPL, you can now open it in Open Office Draw, ungroup it (you will need to repeat this command a number of times) and edit the elements. Save the file as an Open Office drawing (.odg) for use in other Open Office applications. One strange thing I encountered was that the default background for fonts was blue? This seems to be a problem with the import filter, and has been reported on the wiki support page: http://wiki.services.openoffice.org/wiki/SVG_User_Experiences# Blue_background_for_all_text_elements but not fixed. To change this manually: left-click to select a text element, then right-click and choosing Edit Style... and then select White or None from the Area menu. *** As a footnote, I see that an integrated SVG filter, designed to be shipped as part of Open Office, is scheduled to be developed as part of the Google 2007 Summer of Code - see: http://wiki.services.openoffice.org/wiki/Summer_of_Code_2007/p roposals#Draw.2FImpress:_SVG_Import_Filter [EMAIL PROTECTED] 2007/05/15 01:08 AM Not exactly OT. I would not recommend using .eps format in order to export MPL graphs for Inkscape. I've been playing around with Inkscape for a few days now and I've been using .svg exclusively and don't have any problem. As I said before, I like the fact that once I am inside Inscape, I can do an ungroup of the graph, and work with all of the plotting elements individually. In fact, I just discover a nice way to cut and paste a particular subplot over to PowerPoint. This gives me very high quality graphs in Power Point (I can scale all I want). No more fuzzy, ugly-looking Power Point charts. Here's how: a) Create MPL plots in .svg format b) From Inscape, read in .svg c) Select subplot and ungroup d) Copy and paste to a new page e) Shrink the page down to the size of the object f) Save as emf file g) Import into PowerPoint In addition, I am also using Inscape to get around the problem with the PDF backend in MPL. I reported previously that I am unable to save more then 8 PDF files per execuation. Now, I save the files in .svg format, then invoke Inscape in command line mode and export the file in pdf format. Works great.

If you do, you'll see that inkscape will then be able to load .eps/.ps files in a fully editable format. I've used it to fix decade-old plots for which the only thing around was the eps file. I tried to export an .svg from MPL (0.90.0rev3131) with rcParams['text.usetex']=True and got a NotImplementedError (same for the pdf backend with usetex, see attached log). I was wondering: Is it (technically) possible to have .svg export capabilities with usetex-support and if so, has there been no need for this feature so far (not that I need it urgently, just curious..)? There's actually a real MPL bug in there (not just the NotImplementedError) but I'll report it separately in a minute. Anyway, to work with MPL-images (.ps/.eps) in Inkscape, I installed pstoedit but loading these files doesn't work (seems not to recognize them as images). Sorry if I'm driving the Inkscape-stuff a bit OT here, but: What version of Inkscape friends are you using? I'm using pstoedit 3.44, Inkscape 0.44.1. The Latex-formula-feature of Inkscape is also not working and the error seems related to pstoedit. Maybe someone had similar experiences ... Thanks for any hint! Well, unfortunately it seems that
[Matplotlib-users] call for chapeters in a book about freeware/opensource in chemometrics
Dear All, me and other two colleagues will be interested in writing a tutorial book about the use of opensource/freeware software in chemometrics (mainly python oriented). I've contacted the editor at Blackwell publishing that has told me that can be interested in it and sent me the module for submitting the official proposal. I will be very glad to hear from everyone that would like to write a chapter on it. In my opinion it will be the best to have a book with lots of examples that covers simple task, but i will be also glad if anyone would like to write tutorial chapter of less commons subjects. for any feedback just write to me I guess this can be both a change for spread the word of opensouce/freeware togheter with chemometrics also to let know the audience that it's not necessary to invest a lot of money in software for working in chemometrics. Of course, since there are not too much freeware/opensource software in the field, it can be a chance to advertise personal built-in software and to start something new. I hope to receive help and I will be glad to talk with enthusiast all around Giorgio P.S.: (sorry for cross posting) -- -==- Dr Giorgio Luciano Ph.D. Di.C.T.F.A.
