Have you had a look at skimage https://github.com/scikits-image ?
BTW I uses matplotlib (and the whole pylab suite) in my

Hey! :o)
This should be simple, but i cant manage: I need to plot many dots with the
same x, like
plt.plot([3,3,3,3],[60,80,120,180],'+',markersize=8,mec='k')
The array for x values is silly, especially since the number of y values
may be rather large. Is there a way to enter a constant there?

No, but you can do this:
plt.plot([3] * 4, [60, 80, 120, 180], ...)
This started from a simple enough question, but it got me thinking about what
the fastest way to do this is (in case you have HUGE arrays, or many loops over
them). This may be old news to some of you, but I thought

Using int16, int32, float32 get progressively slower to the default float64
case listed on line [5], changing the datatype in other methods doesn't
result in nearly as

Interesting result. Note, however, that matplotlib will eventually turn
all data arrays into float64 at rendering time, so any speed advantage
to using integers will be lost by the subsequent conversion, I suspect.
I don't think it

Since we end up needing float64 anyway:
In [3]: %timeit l=np.empty(1,dtype=np.float64); l.fill(3)
10 loops, best of 3: 14.1 us per loop
nice, fill and empty seem to be responsible for about half the speed up each,
good tools to know

Hi,
for this script:
from pylab import *
fig = figure()
ax = fig.add_subplot(111)
ax.axis('equal')
x = linspace(-2, 3, 50)
ax.plot(x, sin(x))
show()
-
If I try to get ymax with ax.get_ylim(), i obtain 1.0 whereas I observe it
