[Matplotlib-users] variant not working in text()...

2010-05-20 Thread Nick Schurch
Hi all,

I'm adding some text to a plt like this:

import mapplotlib.pyplot as plt
fig=plt.figure()
plt.text(0.5,0.5,some text, variant='small-caps')

but the text that is plotted is not small caps, its just normal. Is
this a bug or am I doing something wrong?

[Matplotlib-users] Another text problem...

2010-05-20 Thread Nick Schurch
I've also discovered another text problem. If I add two lines of test
to a plot as follows:

import mapplotlib.pyplot as plt
fig=plt.figure()
plt.text(0.4,0.5,some text)
plt.text(0.6,0.5,some more text)

then the two sets of text line up nicely with each other, because they
have the same y-axis position. But if I do:

import mapplotlib.pyplot as plt
fig=plt.figure()
plt.text(0.4,0.5,some text)
plt.text(0.6,0.5,some text with a g in it)

then the some text with a g in it is shifted upwards slightly so
that the bottom of some text lines up with the bottom of the g,
and doesn't line up witht he rest of the letters. It look like they
are not on the same line! This has got to be a bug in the way
matplotlib deals with text.

[Matplotlib-users] hist question...

2010-05-19 Thread Nick Schurch
Hi all,

Is there anyway of re-ploting the distribution generated by hist at a
later point? I want to call it in a subroutine and have the resulting
distributions returned so I can plot them without having to
recalculate them each time. I couldn't find anything int he online
documentation but I figured it'd be something like:

import matplotlib.pyplot as plt
hplot=plt.hist(data, bins=1000)

plt.hist(hplot)
or
plt.hist(hplot[0],bins=hplot[1])
or
plt.plot(hist)


etc, but nothing works.

Cheers,

Nick Schurch

[Matplotlib-users] how can I show some figures, but not others?

2010-03-16 Thread Nick Schurch
I have a script that calls several subroutines, each of which makes a
different figure. One of these routines makes lots of figures for use
in a webpage, all of which are saved as they are made. When I call
show() at the end of the script it is showing all the figures (as one
might expect), but what I really want is only some of the figures to
be brought up in the GUI. Is there a way of specifying which figures
show() shows (I can't find anything on the webpage)?

[Matplotlib-users] tabbed figure browsing..

2010-02-15 Thread Nick Schurch
I have a script that calls several subroutines which each draw a
figure (TkAgg backend). When I call show() at the end of the script
all the figures pop up no problem, but when your producing 20+ figures
its a bit overwhelming! It'd be great if I could have just one plot
window with each figure as a tab in that window - is this possible
from matplotlib?

[Matplotlib-users] his problems...

2010-02-09 Thread Nick Schurch
HI all,

I've been using matplotlip for a while now but mainly for line plots,
scatter plots and the odd dendrogram. I recently tried plotting a
histogram (of a binomial function) and encountered a problem. So I
though I'd try the extremely simple example set on the front of the
matplotlib page and heres what I got:

Python 2.4.3 (#1, Sep  3 2009, 15:37:12)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type help, copyright, credits or license for more information.
 from pylab import randn, hist
 x = randn(1)
 hist(x, 100)
Traceback (most recent call last):
  File stdin, line 1, in ?
  File /usr/lib/python2.4/site-packages/matplotlib/pyplot.py, line
1633, in hist
ret =  gca().hist(*args, **kwargs)
  File /usr/lib/python2.4/site-packages/matplotlib/axes.py, line 5060, in hist
align=align, log=log)
  File /usr/lib/python2.4/site-packages/matplotlib/axes.py, line 3253, in bar
assert len(height)==nbars, argument 'height' must be %d or scalar % nbars
AssertionError: argument 'height' must be 101 or scalar

Any idea why this isn't working? I have matplotlib v0.91.2 - will
updating to 0.99 solve the problem?
