Hi ,
I am plotting some date based data (dates/values).
Seems to work ok. The code snippet is below.
But what I am trying to do is set the font size of the (%b)
month labels (Jan,Feb etc) as they are too big for my small graph
and they run into each other ..
ax.xaxis.set_major_formatter( DateF

I suppose you mean vectors in the Matlab way? Then you should have a look at

I'm a sys admin trying to install the matplotlib python package for someone
on our staff. I'm not overly familar with python.
We are trying to use matplotlib with pylab.

Sorry--"self" here refers to an instance of a wxPanel class in my wxPython
app.
It is the parent window for the mpl subplot which is meant to be a child of
it.
The subplot is itself a

Hi,
I have two questions:
1) Is there any way to represent vectors? Currently I'm using 'array' for
vectors.
2) Is there a way to calculate the magnitude (length) of a vector?
Thanks.

Hello,
Thanks to quick hints/tips from Eric and Lionel, I have a module for
conditional plotting and histogramming without defining a table type!
It works with numerical arrays quite well, but does not work on string
arrays in conditions.
I paste the code below since they are quite short. Hope th

Hi all!
I'm new to matplotlib so please excuse me, if this is a bit too simple
problem.
I'm trying to animate simple plot using example anim.py
It works well when I just write functions as follows:
def joonista(x):
line, = p.plot(ala, x)
p.draw()
time.sleep(0.1)
def lpc(x):
x2=emp
Hi Lionel,
Thanks for the tips. The histogram plot I need can be done by hist(x). :)
I tried your commands and I like the find() function! However,
xi = x[ind]
failed with an "IndexError: invalid index". The same operation can be done with
xi = array([x[i] for i in ind])
but if a numpy function c

Hi Ping,
don't know if it could help you :
from pylab import *
> d = Table("xyt.dat")
x,y,t = load("xyt.dat", unpack=true)
> d.plot("x", "t")# make a plot of x vs. t, N points are drawn
plot(t, x)
> d.plot("x") # make a histogram plot of x, N entries in the histogram
bar(range(len(x)),

I don't understand--
Hey Che -
If you include your graphs in a wxPython app, you shouldn't use pylab.
Pylab is a wrapper to (quickly) generate graphs, and is very useful,
especially in interactive mode, as it saves a lot of typing and is much
easier to understand (indeed, a lot like matlab plotting). But for inclusion

Hi,
I checked the manual and briefly searched the mailing list but did not
find this... Is there a table-like data type with rows as events and
columns as attributes that I can make plots with? This is called
"ntuple" in the high energy physics community.
Let me illustrate with an example. Assume
