Re: [Matplotlib-users] Looking for a Compiled Demo of MPL Graphics

[Wayne Watson]

Thanks for the offer, but "potentially" I'm OK on py2exe.  I saw that, 
because I just ran into a snag in an unexpected way. I had tried two 
text output programs with success, then I tried one using pylab, and 
things went haywire. My problem is in route to this  mail list right 
now. An objection to matplotlib.

[Matplotlib-users] py2exe message" RuntimeError: Could not find the matplotlib data files"?

[Wayne Watson]

OK, I'm on Win7.  From the py2exe tutorial,  I've found that  hello.exe
works as expected by the
tutorial. That file is in the dist folder. 
I've now tried this program,
pylab_scatter.py:

#!/usr/bin/env python
from pylab import *
  
N = 30
x = 0.9*rand(N)
y = 0.9*rand(N)
area = pi*(10 * rand(N))**2 # 0 to 10 point radiuses
scatter(x,y,s=area, marker='^', c='r')
  
show()

It runs properly in IDLE.
==
It appears to compile properly. Now from the cmd prompt window:
C:\Users\Wayne\Sandia_Meteors\Sentinel_Development\Learn_Python\Py2exe_Test\dist>pylab_scatter.exe

[Matplotlib-users] Help needed on specific plot

[matplotlib]

Hi,
I have the exterior shape of a nozzle given by S(x). Now what I want to
do is first reflect it with respect to the y=0 axis (easily achieved by
-S(x) right?) and then map each x node's value of an array (say density)
to a color that would fill the vertical space between S(x) and -S(x). In
other words I need something like the matplotlib.pyplot.fill_between
method using x, S(x) and -S(x) but where the fill color would be
relative to a third array (say density again) at each point x.
Thanks!

I've got a small prototype app that embeds MPL in wxPython, bundled up 
with py2exe (and py2app for the Mac). It's 11.7MB, if you want me to 
mail it to you.

Bundled up python apps tend to be big, they have to include all of:

-Your code (not usually very big)

-Python itself (fairly big)

-The gui toolkit (wxPython is very big)

-Any other packages you are using.

Bandwidth and disk space, and memory are cheaper than they used to be, 
so it's not that big a deal, really.

always a good lesson, anyway.

Strange that there wouldn't be any such demos. ;-)  However, I'm now

Re: [Matplotlib-users] finish. now improvement - help

[Pierre de Buyl]

add
"""
import numpy
"""
at the beginning of your code. Then,

y1=[Decimal('0.3041997084285048793446312110'), Decimal 
('0.3041811120982812429734672735'), Decimal 
('0.3041586008929715390350375366'), Decimal 
('0.08256793883349254633032840545'), Decimal 
('0.08255838341506859117962741714')]

(just a subset of your data)
goes to:
y1 = numpy.array([0.3041997084285048793446312110 ,  
0.3041811120982812429734672735 , 0.3041586008929715390350375366 ,  
0.08256793883349254633032840545 , 0.08255838341506859117962741714 ] )
with similar modifications for x1,x2,y2. This takes less place. You  
do not need the "decimal" package in my opinion. Except if the raw  
data you get is the one with the "Decimal" indicators.

Is it too slow ? Is there a reason why you are not satisfied ?

If you want each point to have a separate legend, you should plot  
them separately: a plot(x2[i:i+1),y2[i:i+1],'ro') command for i in  
range(N_points).

Good plotting,

Pierre

Re: [Matplotlib-users] hexbin log bins and colorbar

[Jan Strube]

Hi John,

I am now at r8141.
I don't see a difference. There's a one at the bottom of the scale, that's
all.
I am copying and pasting the code in your other email into a python console.

It's a bit strange, because when I put in a print statement, I see that the
method gets called a number of times...
[edit] I see what's going on. If I replace vv with a large constant (like
100), it never gets printed.
If I replace vv with a small constant (like 1), that is below the range of
the scale, it does get printed at each tick.[/edit]

My setup is kubuntu karmic, dependencies listed below.
I have removed my matplotlibrc, but the result is the same. I am attaching
it nevertheless...

Cheers,
Jan
