matplotlib-users Mailing List for matplotlib (Page 5)

The legend class has been reimplemented recently and the name of some
keyword arguments (and their meaning) has been changed. Those
parameters you're using are deprecated ones. It is supposed to show
you some warnings if deprecated parameters are used, so what you see
is a bug. I'll take a look. I also noticed that the documentaion of
the pylab.legend is outdated. Take a look at

http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.legend

These are lists of deprecated parameteres

                 pad = None,           # deprecated; use borderpad
                 labelsep = None,      # deprecated; use labelspacing
                 handlelen = None,     # deprecated; use handlelength
                 handletextsep = None, # deprecated; use handletextpad
                 axespad = None,       # deprecated; use borderaxespad

So,

  pylab.rc('legend', borderaxespad=0.0, borderpad=0.0,
handlelength=0.0, labelspacing=0.0)

should work.

Thanks,

Can you please provide a screenshot of what you are seeing?

I don't run Mac OS-X myself, so have no experience with the Mac 
OS-X-specific backend...  however, it appears to be drawing regular text 
with native APIs (ATSUI etc.) and mathtext using matplotlib's freetype 
backend and blitting an image.  If done correctly, there is no reason 
why one should be significantly lower quality than the other, but it is 
an obvious source of *difference*, particularly if font size is being 
handled differently in each case.

I would suggest to Michiel de Hoon (author of Mac OS-X backend), to 
implement a full interface to mathtext for his backend (as PDF does, for 
instance) and do all glyph rendering with ATSUI, or the opposite -- do 
all glyph rendering by blitting freetype-rendered glyphs -- but not 
both.  I have some concerns about the use of ATSUI, which, while 
arguably the better text system, will give different results than the 
Agg backends and cause cross-platform differences between plots, which 
is something in general we like to avoid.

Cheers,
Mike

Hi,

please open the legend_demo3:
http://matplotlib.sourceforge.net/plot_directive/mpl_examples/pylab_examples/legend_demo3.py

1. add this line:
pylab.rc('legend', axespad=0.0, pad=0.0, handlelen=0.0, labelsep=0.0)

2. add this line:
pylab.rc('legend', axespad=10.0, pad=10.0, handlelen=10.0, labelsep=10.0)

Why all these parameters have no effect?

Dear all,

I'm using matplotlib together with ipython --pylab and have a plot  
open and can select/deselect points there with the picker and they  
toggle between o and x. When I do that my matplotlib running under

-------------------------------------------------
I'm also using start_event_loop and stop event_loop to make the  
application blocking when starting and unblocking when finished. The  
application works its just annoying seeing this traceback everytime I  
select or deselect a point.

Another thing that sort of worked under linux was that when I clicked,  
it would change immediatley and not wait until I do a refit. Any ideas  
on what to do there?
Thanks

The problem is that you are giving conflicting instructions.  Your axes 
command is initially saying to make the boxes with the given proportions 
of the figure, regardless of the dimensions or aspect ratio of that 
figure; but setting the aspect is overriding that by requiring the boxes 
to be square.  You can still get the behavior you want, however, by 
adding an anchor kwarg to each axes call.  To make sure the
boxes cluster together, add anchor='SE' to the upper left axes, 
anchor='SW' to the upper right, and 'NE' and 'NW' to the lower left and 
right, respectively.

Can someone explain to me how/why the figure normalized [0,1] coordinates
depends on the figsize property? At least this is what it looks like to me.
This affects axes placement and so far I haven't been able to do what I
want.

I want to have square plots placed without spacing between them and with a
little margin on the left and top. So I tried:

s=0.4
axes([0.01, 0.99-s, s, s],aspect='equal')
axes([0.01+s, 0.99-s, s, s],aspect='equal')
axes([0.01, 0.99-2*s, s, s],aspect='equal')
axes([0.01+s, 0.99-2*s, s, s],aspect='equal')

The vertical positioning works as I expected but the x positioning does not
work. The axes have spacing between them - which means that 0.1 represents a
different size in x or in y - and I just can't understand that behavior.

Now if I add:
figure(figsize=(5,5))
it works

But this is not the solution I need because the real plot I'm trying to do
is a 6x5 (6 axes per 5 axes, subplots if you mean) plot with horizontal
spacing only between the 3rd and 4th axes. There is no way I could now the
correct aspect ratio that I should set figsize to, to get it right.

How could I manage this?

Thank you

Ramiro

First, *thank you* to whoever did the Mac OS X backend.  It's much  
faster and smoother, and seems to behave much more reasonably all  
around.  As in, show() actually does what it says it's supposed to do,  
and the figures don't have to be re-sized to draw themselves!

However, there seems to be some kind of strangeness with using  
mathtext.  When an axis label, tick label, title, or other text has  
any mathtext embedded within it, the font that the entire text object  
is rendered in changes, becoming larger, and often fuzzier (in an anti- 
aliased kind of way).

On the plus (though confusing) side, the ticklabels that are being  
output by the basemap toolkit are now the same size as all my normal  
ticklabels, even though they appear to contain a mathtext character  
(the ^\circ for the degrees symbol), whereas previously, all the  
basemap ticklabels were coming out larger than the rest of my  
ticklabels, and I didn't seem to be able to alter them in the normal  
text object manipulation ways.

I'm running on:
Matplotlib SVN: v6677
Mac OS 10.5.6
macosx backend
python 2.5.1
ipython 0.9.1

After I noticed this the first time, I quit out of the interpreter,  
and deleted the font cache from my .matplotlib directory, restarted,  
and the problem persisted.

Any suggestions?  I don't have any of the alternate tex rendering  
options set in my rcfile, just using plain mathtext.

Sorry about that.  This bug has now been fixed in SVN r6661.  It will 
make it into the next maintenance release.

Hello,

I see a significant difference in plots generated with two recent 
versions of matplotlib, and unfortunately not in favour of the newer 
one, otherwise there would be no reason to write here, I guess.

The problem is following, I plot some data wich might be undefined in 
some cases. For example, I plot two lines and one of them has values 
'None' only. Using the 0.98.3 version there is no problem, the graph 
with 'None'-s is just not shown, but with 0.98.5 the y-scale is 
something close to zero only, if the first line is 'None'-s and I do not 
see the plot for other line as well.

I add simple code, which works fine with 0.98.3 and not with 0.98.5. It 
is definitely not difficult to make a workaround, but for some reason I 
like the behaviour of previous version better and if there is no need to 
change it, maybe we could turn it back into situation, where one line of 
missing data would not destroy the whole graph.

Best regards,

What's the problem here? this looks successful to me. If you're 
referring to the "Upgrading" -- I think that's because the Mac pkg 
installer keep some kind of record that is separate from the python tree.

At home without my Mac, so can't test myself now -- sorry.

Hi John,

This is odd. After successfully installing the egg (last post) and then removing 
it by doing

sudo rm -rf 
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib*

I now get
sudo installer -pkg matplotlib-0.98.5.1-py2.5-macosx10.5.mpkg -target /
installer: Package name is matplotlib 0.98.5.1-r0
installer: Upgrading at base path /
installer: The upgrade was successful.

So there are some files I haven't gotten rid of, what should I be looking to remove?

Thanks!

Yess! The renaming works. Would simply changing the name of the file on 
sourceforge solve this problem? That would be so odd! Thanks -Kaushik

I downloaded keypress_demo.py from the matplotlib website

runs as follows

now you are making me think something is wrong with my build, but
this is an out of the box laptop, 10.5, numpy 1.2.1, zlib-1.2.3,
freetype-2.3.7, libpng-1.2.33, then build matplotlib-0.98.5

J

note: i backed down to 0.98.3, it works fine

Eggs are an abomination -- the person who named the installer
"easy_install" should have their license revoked.  I think we may
distributing them because they are simply broken in too many ways.
This recurring problem -- where the easy_install goes looking on pypi
for an egg even though you are pointing at one locally on the file
system, is simply ridiculous.

Chris Barker suggests renaming the egg to matplotlib-0.98.5-py2.5.egg.
 Try that, and please let me know.  Thanks for the testing.

Please run the following commands after cleaning the previous installs
and reinstalling the mpkg file::


   ls
   python -c 'import matplotlib; print matplotlib.__file__'
   python -c 'import matplotlib; print matplotlib.__version__'
   python -c 'import pylab'

The ls is important because sometimes a person has a directory named
'matplotlib' in their local path, and this is getting picked rather
than the installed matplotlib which contains the pylab module.

I am not seeing this on the 0.98.5 release candidate.  I fire up

 > python simple_plot.py -dTkAgg

and click 'c' somewhere on the figure/axes, or 'delete' and I am not
getting the traceback.

Using matplotlib 0.98.5 on OSX 10.5, the following error
occurs for many key_press events using the standard
connect class - letter such as c,v,s etc (and most important, backspace)
