Hi,
I think there is a good reason to add the functionality to plot
pre-computed histograms to hist() or to a new function with similar API.
Sometimes histograms are heavy or we don't want to recompute them to
perform a series of plots.
In this case, I miss the ability to easily set the plot sty

Hi to all,
I'm computing some spectrograms using the convenient functions defined in
matplotlib.mlab.
I found something that I don't completely understand. In computing the PSD
the onesided power spectrum is scaled by a factor of 2 except for the first
and the last bin:

Hi to all,
I'm doing a simple animation like this:
--
ion()
x = arange(0,2,0.01)
y = zeros_like(x)
y[45:55]=1
l, = plot(x,y)
D = 0.1
h = x[1]-x[0]
dt = 0.0001;
def nabla(v,h):
na = zeros_like(v)
na[1:-1] = (v[2:]-2*v[1:-1]+v[:-2])
na[0],na[-1] = 0,0
return na/(h**2)
for i in ra
indow resizing.
Furthermore the MPL navigation toolbar is modified through the addition of two
custom buttons.

HI to the list,
I'm playing with blit animations in a gtk window. Looking at MPL
examples I came up with a working example (attached) that shows a sin
wave with a play toggle button and a "scale" button that changes the
axis limits. In order to plot the first frame (before play is clicked)

You can do it this way:
data = array(data)
x = arange(len(data))
plot(x[data!=0], data[data!=0])

In interactive mode:

ax = gca()
ax.set_xscale('log')
ax.set_yscale('log')

The other parameter .set_xscale and set_yscale accept is 'li

pixel each one (or more) seconds.
I'm running the script from "ipython -pylab" using the command "run
