[Matplotlib-users] AXES properties
BTW: I tried to use set_position to change the position of the axes label as suggested by previous posting. No effect. - Original Message Hello, I am creating a plot with multiple y-axis (up to 6) and twinx works pretty well. The problem is that there are too much wasted spaces used up by the axes. Since I have multiple axes, it cuts into the amount of space available for the plot area. I need to know how I can squeeze some spaces out of the standard axes. First thing I discovered was that I can rotate the tick labels to vertical by: plt.setp(ax.major_ticklabels, rotation=vertical) where ax is my y-axis. But then: (1) How to reduce the space between the tick and the axes label? First I tried to place the label on top but couldn't get that to work. Then I tried to change the position property of the axis label object and that have no effect. So, can somebody please tell me how I can do these 2 things? (2) How to avoid overlapping tick labels? With the way the standard x and y axis are drawn, after I do a vertical rotate of the y tick labels, the first y tick label overlaps with the last x tick label since they are both center aligned. Is there any way to change the alignment of only the first and last tick labels of an axes (while keeping the rest center aligned)?

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
I *finally* got this to work!!! Thanks to Werner's message, I found the culpit: the matplotlibrc file copied to the dist directory contains the TkAgg backend. All I had to do is to change *that* file to say: backend : WXAgg Note that it's not the matplotlibrc in the installed copy - but the one in the resulting dist directory. In addition, I have to do a: set MATPLOTLIBDATA=.\mpl-data before I start the exe file. I don't know why this is necessary because the code for _get_data_path appears to look at that directory by default but if I don't set this, it can't find the data files. In any event, it works now - after bumping head for 2 weeks! Thanks everybody. -Original Message- From: Werner F.

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
Ok, I know what the problem is. I was using a sample setup.py posted by Stef and in his setup, he created a mpl-data subdirectory under dist to store all of the data files use by matplotlib. That's why matplotlib couldn't find it without a set statement. After changing the name to matplotlibdata, everything works. I also made changes to every one of the matplotlibrc file I found in the installed copy of matplotlib to invoke WXAgg - instead of TkAgg. So for completeless, may be this will benefit other matplotlib users, here's my py2exe script - tested using python 2.3, latest wxpython and so forth. Let say you wish to create an exe of the sample multicolor.py program. Place multicolor.py in a test\multicolor directory, and a copy of the following script, have py2exe installed, and then just run it. You will end up with a dist subdirectory under test\multicolor and that's where you'll find multicolor.exe. # Kill_Distro = True MatPlotLib_Wanted = True def File_Exists( path ): res=os.path.isdir(path) if res==True: return res return os.path.isfile(path) from distutils.core import setup import py2exe import sys import os import shutil import glob homedir= rE:\test\Matplotlib\multicolor python = rc:\Python25 # Name of python directory if File_Exists(python)==False: python = rc:\Python23 # Name of python directory # *** # Some suggests that old build/dist should be cleared # *** dist_paths = [ homedir+'\\build', homedir+'\\dist' ] for path in dist_paths : if File_Exists ( path ) : shutil.rmtree ( path ) # *** # *** # *** data_files = [] packages = [] includes = [] excludes = [] dll_excludes = [] data_files.append ( ( '', glob.glob ( 'templates_*.*' ) ) ) # *** # For MatPlotLib # *** if MatPlotLib_Wanted : import matplotlib includes.append ( 'matplotlib.numerix.random_array' ) packages.append ( 'matplotlib' ) packages.append ( 'pytz' ) def mpl_data_files(destpath, path): mpl_data=[] for x in glob.glob (path+'\\*.*' ): if os.path.isdir(x): mpl_data_files(destpath+'\\'+os.path.split(x)[1], x) elif os.path.isfile(x): mpl_data.append(x) data_files.append ( ( destpath, mpl_data)) mpl_data_files(r'matplotlibdata', python+r'\Lib\site-packages\matplotlib\mpl-data') data_files.append ( ( r'matplotlibdata', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\matplotlibrc' ))) data_files.append ( ( r'matplotlibdata\images', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\images\*.*' ))) data_files.append ( ( r'matplotlibdata\fonts\afm', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\afm\*.*' ))) data_files.append ( ( r'matplotlibdata\fonts\pdfcorefonts', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\pdfcorefonts\*.*'))) data_files.append ( ( r'matplotlibdata\fonts\ttf', glob.glob ( python+r'\Lib\site-packages\matplotlib\mpl-data\fonts\ttf\*.*' ))) excludes.append ( '_gtkagg') excludes.append ( '_tkagg' ) excludes.append ( '_agg2' ) excludes.append ( '_cairo' ) excludes.append ( '_cocoaagg' ) excludes.append ( '_fltkagg' ) excludes.append ( '_gtk' ) excludes.append ( '_gtkcairo') excludes.append ( 'backend_qt' ) excludes.append ( 'backend_qt4') excludes.append ( 'backend_qt4agg' ) excludes.append ( 'backend_qtagg' ) excludes.append ( 'backend_cairo' ) excludes.append ( 'backend_cocoaagg' ) excludes.append ( 'Tkconstants' ) excludes.append ( 'Tkinter' ) excludes.append ( 'tcl' ) excludes.append ( _imagingtk ) excludes.append ( PIL._imagingtk ) excludes.append ( ImageTk ) excludes.append ( PIL.ImageTk ) excludes.append ( FixTk ) dll_excludes.append ( 'libgdk-win32-2.0-0.dll' ) dll_excludes.append ( 'libgdk_pixbuf-2.0-0.dll' ) dll_excludes.append ( 'libgobject-2.0-0.dll') dll_excludes.append ( 'tcl84.dll' ) dll_excludes.append ( 'tk84.dll' ) dll_excludes.append ( 'tclpip84.dll' ) # *** #
Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...
With Stef's help, I was able to get pass the Matplotlib datafile not found problem in using py2exe and Matplotlib under Python 2.3 - but then ran into the same Tkinter not loaded problem like he did. After reading Stef's messages from this list, I downloaded the latest version of Matplotlib - only to find that Python 2.3 is no longer supported. So, I loaded up Python 2.5 and ran the setup script for Py2exe. Now, py2exe is unable to find wxmsw26uh_vc.dll - eventhough I have wxPython 2.8 installed. So, I dug up a copy of wxPython 2.6 and have that installed. The file is now there but py2exe still can't find it. This is very fustrating!

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!

Bingo! My prayer appears to have been answered. inkscape has no trouble reading the .svg files created by MPL, and Word has no trouble reading the .eps files created by inkscape. So, at least I can use it to preserve the vectors. Too bad inkscape doesn't read .eps directly (complaining...complaining) :=) inkscape treats everything as objects and allows you to ungroup the plots into elements and then you can play with each of the elements individually. When I am done, I can then insert into Word. Too bad it doesn't allow me to paste the objects directly over to Windows but I am not complaining.

Re: [Matplotlib-users] SVG vs PNG
inkscape has no trouble reading the .svg files created by MPL, and Word has no trouble reading the .eps files created by inkscape. hmm. I wonder what it is about MPL's .eps files that Word doesn't like. Bug in MPL or Word?? Most likely Word. It's very picky. I have .eps files created by other programs where Word would simply tell you that it's not a supported format.

Re: [Matplotlib-users] SVG vs PNG
Actually, Gimp is the problem. It's obvious they don't have a very good rendering engine. The plots looks very good under Inkscape. The quality of the svg plot depends in large plot on the svg renderer -- perhaps word doesn't do a good job rendering SVG? The matplotlib PNG files look good because agg is a good rendering engine.

[Matplotlib-users] This is just so perfect! (was: Re: SVG vs PNG)
This is simply too good to be true. I played with manupulating MPL plots using Inkscape and man, somebody ought to include this in the MPL FAQ. I can move everything around by elements, touch-up or remove things I don't want, scale it, rotate it, you name it. And then I can save the file in .eps and include into Office - and I don't loose any quality. Perfect! Here's what I learned: a) Create the plot under MPL, saving the file in .svg format, and use the figsize argument to figure to create a plot of the proper size b) Use Inkscape to open the .svg file and manupulate it. Save in .eps format. c) Import the .eps file into Office. d) Be happy and become famous and rich. (not) Thanks again for all of the suggestions and tips.

[Matplotlib-users] Axes label
I found an example on the web that illustrates the question I posted earlier about axes. See: http://www.scipy.org/Cookbook/Matplotlib/MulticoloredLine Notice that the y-axis goes from (-1.1, 1.1) but the first label is at -1.0. I really don't like that because when I read values off the graph, I have to keep reminding myself that the origin is at -1.1. This may seem trivial but if you have to think, walk, chew gums at the same time you're reading the graph, it gets annoying - particularly if you have to read lots of these graphs. Is there a way to force the label to start at -1.1 instead of -1.0? Thanks, -- John Henry - Take Surveys. Earn Cash.

Re: [Matplotlib-users] invalidrestore
Thanks for the answer, John. Up to this point, the other software package we use produces EPS files only and so I've been using it this way for a while. May not be the best way but I've tried other EPS viewers and so far Word actually is the best way since I have to embedd the plots into Word reports. Back to the subject at hand. Using PNG files works but brings with it other problems and so I would really appreciate a resolution to this invalidrestore issue. I can't use PDF because I have to embedd the plots in a Word document. Not sure what SVG is (I'll look it up). Regards, Using PS/EPS in Word or any office product is a pretty unusual combination. My experience is that they are not supported s well as other image formats. Will PNG work for you? That is what I usually use for Office. You may also consider PDF or SVG if you need vector graphics.

Re: [Matplotlib-users] invalidrestore - PDF
Switching to PDF works (eventually - see below) but bring with it yet another set of problems. First of all, I had to fix backend_pdf.py for MPL to work (w Python 2.3, anyway). Two problems: a) 2.3 doesn't have the sorted function - it uses a .sort() function. So, I had to change line 487 from: chars=sorted(charmap.keys()) to: chars = charmap.keys() chars.sort() b) No update() function (line 396) So, instead of: xobjects.update([(name, value[0]) for (name, value) in self.markers.items()]) Had to do: for (name, value) in self.markers.items(): xobjects[name]=value[0] After that, I got my pdf file. However, if I print the PDF directly, works fine but when I create an object link to the PDF and print from inside Word, the printout is degraded (kind of fuzzy with texts). So, for a temporary work around, I can use PDF instead of EPS and hopefully that problem will get fixed someday. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jouni K.

Re: [Matplotlib-users] invalidrestore - EPS file
I installed gsview and gs and tried it. AFAIK, gs didn't seen to complain. I also tried GIMP. While it didn't complain, the picture displayed is horribly bad. An invalidrestore error signals an improper restore. E.g., a string, dictionary, or procedure is left on the stack that needs to be discarded before restore. Probably a dictionary with no 'end'. Two obvious possibilities: - there is an invalid restore. This should be fixed. - something is wrong with the Word interpreter (quite possible given its history, but perhaps surprising for this particular problem) Does GhostScript report the same error? fwiw, Alan Isaac -- John Henry - Take Surveys.

[Matplotlib-users] invalidrestore
Hi list, I am getting an invalidrestore from the printer when I print a figure created with MPL. The page prints fine but for each plot, I am getting an error page. I didn't have this problem until I started making a number of font related changes. Before I go through a bunch of painful regression steps to see what causes this, does anybody has experience in this? Don't know if it matters but I am using Word to print the .eps file by imported it into a word doc file and then print from there. I am using Word because I don't have any other software that would allow me to print .eps file. Regards, -- John Henry - Take Surveys. Earn Cash.

Re: [Matplotlib-users] invalidrestore
I installed gsview and gscript and tried it. The good news is that when I print from inside gsview, the error page is gone. The bad news is that the oritentation is wrong. My plot is designed for landscape. From word, I set the page setup to landscape, import the picture, and print. But with gsview, it imports my plot 90 degree wrong. Changing orientation flips the whole page 90 degree but the plot gets rotated as well and so it still prints wrong. I guess I have no choice but to regress step by step and see which MPL feature aggrevated this condition. -Original Message- From: Eric Firing [mailto:[EMAIL PROTECTED] Sent: Friday, February 23, 2007 12:06 PM To: [EMAIL PROTECTED] Cc: matplotlib-users@lists.sourceforge.net Subject: Re: [Matplotlib-users] invalidrestore [EMAIL PROTECTED] wrote: Hi list, I am getting an invalidrestore from the printer when I print a figure created with MPL.

Re: [Matplotlib-users] invalidrestore
Thanks for pointing that out, Eric.
I try that and it did turn my plot 90 degree. The bad news is that GSview
imports it upside down and if I want to view the plot on the screen, I have to
rotate it downside up first. (Hey, I shouldn't complain. At least I can
print without wasting a piece of paper for each plot).
So, looks like it's true that something MPL did to the eps file is causing Word
to spit out that error page. I wish I know what it is.
The problem of not finding out is that I need to send these plots to clients.
I don't want to require that they have an .eps viewer in order to see my
plots...

Did you try saving the figure using the orientation kwarg? This is
intended for postscript output.
e.g.
from pylab import figure, show, close
fig = figure()
ax = fig.add_subplot(1,1,1)
ax.plot([0,1], [0,1])
fig.savefig('myplot.ps', orientation='landscape')
close(fig)

[Matplotlib-users] Controlling vertical space between subplots
Hi list, I have a figure of 3 rows by 2 col of plots. I have a need to use 2 line xlabels for each of the subplots. So I did something like: xlabel(Label 1\nLine 2) for each of the subplots. However when I do that, the 2nd line is lost for the top 4 subplots because I don't have enough vertical spaces between them. I tried something like: subplots_adjust(hspace=0.4) but it didn't seem to have any effect (I also tried different values for hspace - no effect at all). What am I doing wrong? I also have too much white space on the left and right side of the page and I tried to reduce that using the subplots_adjust function but it didn't seem to be doing what I want. I am sure I am not understanding something about subplots_adjust. Could some one please clarify it (or point me to the right direction)? Thanks, -- John Henry - Take Surveys. Earn Cash.

Okay, I tried saving using the postscript format, and I end up with the ugly plot also. In fact, if I maximize the plot and then save as .ps file, I get ugly plot as well.
