The linestyles can be obtained as the keys of the
matplotlib.lines.lineStyles dictionary; the markers are the keys of
the matplotlib.lines.lineMarkers dictionary

  In [95]: matplotlib.lines.lineStyles.keys()
  Out[95]: ['None', '--', '-.', '-', 'steps', ':']

  In [96]: matplotlib.lines.lineMarkers.keys()
  Out[96]: [0, 1, 2, 3, '+', ',', '.', '1', '3', '2', '4', '<','>', 
            'None', 'D', 'H', '_', '^', 'd', 'h', 'o', 'p', 's', 'v', 
            'x', '|']

The list of valid colornames are the keys of the
matplotlib.colors.cnames dictionary

  In [97]: import matplotlib.colors

  In [98]: colors = matplotlib.colors.cnames.keys()

  In [99]: len(colors)
  Out[99]: 139

  In [100]: colors.sort()

  In [101]: colors[:5]
  Out[101]: ['aliceblue', 'antiquewhite', 'aqua', 'aquamarine', 'azure']

Hi list,

I'm having some font weirdness using matplotlib 0.87.4 on MacOSX with  
the WXAgg backend.
It's a clean install of universal builds from macpython.org.

First of all, when lauching for the first time (or if I delete the  
font cache), I get:

Then, if I try to save a plot in eps, nor Preview.app nor Illustrator  
can open the eps file. Furthermore the file is huge (several MB) for  
a very simple plot.
If I save the plot as a svg, then I can open the file with Firefox or  
Illustrator, although Illustrator complains about a "missing font"  
and substitute it with its defaut font. I've looked onto the svg file  
and it should use Lucida Grande, which is available on the system...

I've read on this very list that I might solve some issues by putting  
the Bitstream familly of fonts as first choice in my matplotlibrc,  
which I did.
In these conditions, saving as eps yields a file which can be opened  
by Preview.app, but opening it in Illustrator results in a plot where  
every fonts are replaced by little boxes (see attached picture)

i've gone something similar using separate masked arrays on my data set,
see
http://www.scipy.org/Cookbook/Matplotlib/Plotting_values_with_masked_arrays, for how to do this.

I have a look like this:

    for i,_ in enumerate(myRunObject.results[0]):
        pylab.plot(x, counts[i])

That will plot a bunch of curves and I would like the point style to change
as well as the colour (which changes automatically). Is there a nice way to
do this? The only idea I had was to make a list of the possible point styles
that I like and grab a point style from that list according to the index =
mod(i, len(listOfPointStyles))

Werner,

Thanks for your work in solving this problem. I'm experiencing the same trouble.
I can compile to .exe if I exclude wxmsw26uh_vc.dll, but then when I run my
final .exe, I get a error dialog popup and the program won't run.

The dialog says "The procedure entry point ?GetZoom@wxPrintPreview@@UBEHXZ
could not be located in the dynamic link library wxmsw26uh_vc.dll"

Did you experience this problem after compiling with 
an excluded wxmsw26uh_vc.dll?

BTW, I'm working with Python 2.4, the unicode verison of wxPython,
and windows XP.

With Regards,

Daniel McQuillen

Daniel:  If you know what the lat/lon boundaries of all the tiles are 
beforehand, you can create Basemap instances for all those tiles once, 
then save them to pickles and have the app just load those pickles on 
demand.  That way you will avoid the overhead of creating the Basemap 
instances, which can be significant, especially when higher resolution 
boundaries are used (since all of those boundaries have to be 
transformed from geographic to projection coordinates when the instance 
is created).

Hi,

I'm using django and basemap to render tiles i can use to make an
overlay on google maps. I'm using this to generate a topology of an open
mesh network (freifunk) here in leipzig :)
On my local developing machine this works very nice and due heavy
caching of database lookups it doesn't seem slow. My problem is, that
the production machine isn't that fast and has to little memory :(

Now I'm thinking of a better algorithm to generate the tiles. Currently
they are generated on demand and then saved to disc for later usage. But
the topology is fetched every 10 minutes, so the disc files timeout
relative fast.

my current algorithm looks like this:

fetch all node positions and cache them through pickle.
These are rendered as small blue dots on the map (Yes, here I can
optimize to only call plot when the node is in boundries of the tile.

then all connections for the last topo are fetched and cached.
Now there is a problem, I have to plot all connections into the plot,
because it's not easy to say which lines are actually in the tile. I
haven't looked deep into matplotlib to know how optimized it already
ignores plots which are out of bound.

Now I'm asking my self: is it possible to make a basemap instance with
some lat/lng borders, plot all stuff in it, and then move the borders to
get a new tile which is next to the last one ? Would such a algorithm be
faster then the current one ?

If not, there is also the posibility to create one large image at
largest zoomlevel for the most used region and then cut and scale the
image until all tiles are generated.

You can find the sourcecode at:
http://ff-firmware.quamquam.org/trac/browser/ffsomething/trunk/apps/uptime/topoimg.py
mktopo() is acutally doing the work :)

kindly regards

Hey guys:

Charlie I did not find your lasso example so I cooked up mine, I attach it.
Can you give me the file name that contains the new Lasso widget for  
"doodling" ?

This is just the start of the lasso or "region of interest" widget I 
still have to :
    - fill the region with a color
    - make it work with layers
    - add methods that return the pixel region or the contour coordinates
    - make a nice class

If anybody has made such a widget I would love to see the code, I hate 
reinventing the wheel.

If there is not such an example such as the lasso tool, can my example 
be added to the examples ?
What is the process ?

Anyway, I can't believe there is not such a widget, I thought there must 
be some people that use matplotlib for Digital Image Processing ?
Isn't there ?

Any critique on my code would be appreciated, I have never programed 
with matplotlib ...


                                                                   Daniel.

Hi,

Sorry for posting to the list, but I had no clue who to address.

Recently I had some troubles sending emails to the list, for they were bounced 
back with this delivery status notification:

The following message to <mat...@li...> was 
undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 550-'Postmaster verification failed while 
checking <prv...@un...>\n(result of earlier 
verification reused).\nSeveral RFCs state that you are required to have a 
postmaster\nmailbox for each mail domain. This host does not accept 
mail\nfrom domains whose servers reject the postmaster address.\nSender 
verify failed'

What then follows is my entire mail I was going to send.

Unsubscribing / Re-subscribing helped. matplotlib-users is the only list where 
I had such problems, but not the only one using Mailman I'm using.

Could this be a problem with the mailserver I'm using?

My apologies if this is not considered to be of general interest. Please reply 
directly to my address in this case.

TIA
Christian

Hi,

Thanks for all the ideas I got. I'll try them and see what's best / easiest 
for my problem.

Thanks,
Christian

PS Sorry, I accidently send this to Richard only at first ...

Isn't the "current" version using numpy 0.9.8? No matter, they are ALL 
beta, (or alpha), so there is no reason to stick with any particular one.

1.0b seems to be the least buggy and most future-proof (which, of 
course, doesn't mean that much) at the moment, so I say we do it.

Charlie, can you do OS-X? I still don't have my build environment set up 
quite right, and you beat me to it last time. We'll need to  put a new 
numpy mpkg on pythonmac.org at the same time. I'd be glad to do that, if 
it helps, but I need to make sure we use the same version.

-Chris

Hi,

i have nearly the same problem. I need to make plots
in which the text, axea and labels are either in
english, frensh, german, spanish or italian. I use
wxPython and in the main-program it woks with the
languages, but the plots have these little squares in
the text if there has to be a umlaut or special
chracter. The unicode demo works as long as the plot
is not embedded in wxPython. With wxPython only
"self.axes.set_ylabel( unicode('Andr\xc3\xa9 was
here!', 'utf-8') )" is working. The other texts have
some weird characters in it. Here is the code to check
yourself:

# -*- coding: utf_8 -*-

from wxPython.wx import *
import gettext
from pylab import *
matplotlib.use('WXAgg')
from matplotlib.backends.backend_wxagg import
FigureCanvasWxAgg as FigureCanvas
from matplotlib.figure import Figure

class GraphFrame(wxFrame):
    def __init__(self, parent, ID, title):
        wxFrame.__init__(self, parent, ID, title,
size=(650,450))

        self.figure = Figure()

        self.axes = self.figure.add_subplot(111)

        self.axes.plot([1,2,4])
        self.axes.set_title( unicode('Développés et
fabriqués', 'latin-1') )
        self.axes.set_xlabel( unicode("réactivité nous
permettent d'être sélectionnés et adoptés", 'latin-1')
)
        self.axes.set_ylabel( unicode('Andr\xc3\xa9
was here!', 'utf-8') )
        self.axes.text( 0.5, 2.5, unicode('Institut
für Festkörperphysik', 'latin-1'), rotation=45)
        self.axes.text( 1, 1.5, u'AVA (check
kerning)')  

        self.canvas = FigureCanvas(self, -1,
self.figure)
        self.sizer = wxBoxSizer(wxVERTICAL)
        self.sizer.Add(self.canvas, 1, wxLEFT | wxTOP
| wxGROW)
        self.SetSizer(self.sizer)
        self.Fit()
        
class MyApp(wxApp):
    def OnInit(self):

        # Install gettext. Once this is done, all
strings enclosed in "_()" will automatically be
translated.
        gettext.install('MyApp', './locale',
unicode=True)

        # detect the user's default language setting
        loc = wxLocale
        userLang = loc.GetSystemLanguage()

        frame = GraphFrame(None, -1, _("Graph Frame"))
        self.SetTopWindow(frame)
        frame.CentreOnScreen()
        frame.Show(True)
        return True

def main():
    app = MyApp(0)
    app.MainLoop()

if __name__ == '__main__':
    main()


The problem is that i do not know all texts to be
shown, as the name of the user should be written as
title.

I am using Windows XP, Python 2.3, wxPython 2.6.1.0
and Matplotlib 0.85

Thanks

   Till Wagner

I wonder how long we should continue to hold off on a new release. As I said 
in a previous email, Travis does not foresee changes to the C API before 
numpy-1.1 (although he doesn't rule them out). Besides, several bug fixes and 
new features have been added since 0.87.4.

Here is a link to a build that works with numpy-1.0b1.  Pushing a
release now for 1.0 might be pointless, since the C-api could possibly
change and break compatibility again.  After all, it still is a beta.

Hi,

using matplotlib-0.87.4

uname -a == "SunOS maples 5.9 Generic_112233-07 sun4u sparc
SUNW,Sun-Fire-280R"

gcc --version == "2.95.3" (have no control over this)

python -V == "Python 2.4.3" (in $HOME/local/bin)

I get some errors during "python setup.py build" (with all GUIs disabled
in setup.py, but BUILD_IMAGE=1 and BUILD_AGG=1):

When I fix this (by #include <cstdio>) it gets more errors about
redefining _FILE_OFFSET_BITS:

Please help, I've already written code using matplotlib under windows
and don't want to rewrite it for the move to Solaris.

Thank you,
Jett

P.S. while Windows version works fine, compiling under cygwin yields
problems like being unable to import the _agg DLL (and twiddling
permissions doesn't help) - ideas?

Does anyone know when the matplotlib install will be able to work with numpy1.0? numpy0.9.8 has a memory leak that crashes my program :(.

thanks!

You probably have numpy-0.9.6 installed.  0.87.4 requires numpy-0.9.8.

More information:

I realized that I was 4 versions behind, the error I was seeing was in 
version 0.87

However:
Version 0.87.1 has the same error

Version 0.87.2 gives the following (though it works afterwards):
Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> from pylab import *
C:\Python24\lib\site-packages\matplotlib\font_manager.py:456: 
UserWarning: Canno
t handle unicode filenames
   warnings.warn("Cannot handle unicode filenames")
 >>>

Version 0.87.3 seems to work just fine (no noticeable errors).

Version 0.87.4 causes a full interpreter crash with no errors (the crash 
raises one of Window's infamous "* has encountered a problem and needs 
to close.  We are sorry for the inconvenience." dialogs).


So, I've got a temporary solution, in that I can just use version 
0.87.3, but it's not a permanent solution as development of matplotlib 
goes forward.  If anyone can explain what's going on I'd appreciate it.

Look in at the widget examples.  There is a new Lasso widget for
"doodling" and a RectangleSelector.

A unicode character in your font path?  Weird.  Try deleting your font
cache in your ~/.matplotlib folder.  On windows it is somewhere in
your home folder.

After installing matplotlib from the Window's binaries (a process which
goes off without a hitch), I get the following error when trying to use it:

Hi:

Just stared playing with matplotlib, I want to draw a polygon on top of 
an image to select a region of interest in the image.
Does anybody have any example or advice on how to interactively draw a 
polygon with the mouse by placing it's vertices's one click at a time ?
Another case that I have would be just to fill a region with a thick 
line, searched for a "doodle example" or a "paint example" but could not 
find them, any advice would be appreciated too.

      

                                                                      
Daniel.

Hi all, i was wondering if any one has implemented a simplex drawring 
package for matplotlib, eg. for diagrams such as this 
http://www.santafe.edu/~dirk/ccant_wf2/img72.gif.


Thanks in advance
