Hello everybody,
I have a problem transferring from 3D data to a 2D representation.
I used mayavi to define a cut plane through a volume data set and got
the xyz
coordinates for the points on the plane and the data at each point.
Now I would like to make a contour plot of that data in matplotlib

Hi Nicolas
Thanks for the post. I'm going to finish optimizing all of the
non-rendering pieces of my code, then I'll see if trying the hardware
rendering makes sense. Right now I am software rendering 3.5 million
triangles in about 5 seconds, but the setup (masking etc) is taking
about 40.

[8,4]
These questions belong on the numpy mailing list. You have already asked this
question on scipy-user and r
Hello,
Do somebody knows how to keep only the x first terms of a numpy 1D array?
like
a = array([8,4,5,7,9])
function(a,2)
>>> [8,4]

Hi, thanks for that. I've made the following changes:
NFFT = 100*60*10# Linked to window size
Fs = stream[0].stats.sampling_rate
win = np.hanning(NFFT)
overlap = NFFT/2
power, freq = plt.psd(data, NFFT, Fs, win, overlap)
but it returns the following error:

Hi I have some data for a 24hr period with a sample rate of 100
samples/second. I want to create a power spectrum using matplotlibs
function psd. I want it to have 10 minute windows with a 50% overlap, but
cant seem to get the syntax right. My code is as follows:
NFFT = len(data)
Fs = 100
window=n
Hi
Thank you very much, it worked perfectly :D
Kind regards
