If there are a set of data points being plotted in a
subplot, say 0 to 1000 points; the subplot displays
the ticks as 0 to 1000 points and it is desired to
"translate" those points to 0 t0 250 points on the
subplot display - with point 0 mapping to point 0,

Not sure if I understand, but I think this is what you want to do:
y = rand(1000) # your 1000 random points
x = linspace(0, 250, y.size)
plot(x,y)

Does this handle the case where the user has specified bins of
different widths? It looks like you are onl
Thanx for the response..
I'd like to avoid the pylab interface...
linspace is good.
assume you have 1000 points of data and you'd like the
ticks to display from 0 to 4, since the 1000 points of
data were sampled at 250 Hz.
any "non-pylab" ideas ? Indexlocator?

Hello List -
I have been using IDLE with the -n option to run matplotlib interactively.
Now today I decided to install Python 2.4.4, using the win32 installer on
the python webpage.
Normally I use the Enthought edition (which I like a lot), but they haven't
released a new version with numpy 1.0

from matplotlib.mlab import linspace
But linspace may not be what you want. Probably better:
In [1]: Fs = 4. # sampling at 4Hz
In [2]: dt = 1./Fs
In [3]: import numpy
In [4]: ind = num
I apologize if I haven't been sufficiently clear.

Wouldn't it make sense to simply change the xticks to
reflect the time instead of the number of data points
?
Like, if we needed to display 0 t0 1000 points over a
period of time, wouldn't it be nice to translate the
xticks to reflect the period of time ?
Would you suggest using IndexLocator in

I have experimented with every conceivable python/numpy/mpl

Use the pythonmac.org packages with the wx backend. Choose whichever

Actually, now that I think about it, there is not enough information
in the bin centers to know the widths of the bins if they may vary.

The plot method (plot(self, *args, **kwargs)) accepts
only x,y pairs, in ax.plot(ind*dt, y) -- the x
parameter is ind*dt - the sample times, but the data
between the sample points is lost. IMHO, the likely

John,
One of the problems we've had is trying to design an auto-scaling
algorithm that works well with any type date format since the date
strings can be so large horizontally. I believe that having the draw
time elements be able to query the renderer for things would help
this out tremendousl
There seems to be a huge misunderstanding here, and I am not sure what
it is, but what you need to do is run examples and experiment with
variations until you have some inkling of what mpl is actually doing.
Start with http://matplotlib.sourceforge.net/tutorial.html.

Hi,
a problem that I have since some time now using mpl: everytime I start
plotting, I get something like:

ppd character encoding: ISOLatin1, trying CSISOLatin1
I know this is not really a mpl problem, but if anybody has a cl
With all respect, I have certainly perused the
tutorials before posting the question. I'm still a
newbie and I acknowledge I have miles and miles to go
before I can be someone who can help out in the
Matplotlib group like you guys do.
The problem is simple, it is like the date examples in

Just started using matplotlib (it's great!) interactively (using ipython,
TkAgg backend) and am moving into saving plots to file.
I edited the matplotlibrc to interactive: False and backend: Agg, and it
works great. (produces .png)
I would normally like to muck around interactively to get the p
