On my machine these are rather confusingly different functions, with the
latter corresponding to numpy.random.power. I appreciate that pylab
imports everything from both the numpy and numpy.random modules but
wouldn't it make sense if pylab.power were the oft-used power
function rather than a mean
Hi,
I have this issue, schematically:
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0.0, a, b)
for i in range(d):
y1 = f1(x, p1_i, p2_i)
y2 = f2(x, p1_i, p2_i)
plt.scatter(x, y1, c=color[i])
plt.plot(x, y2, '-', c=color[i]
my question:
how
Hey Will,
As a user, all I can tell you is that pylab is there for convenience when:
1) quickly and interactively exploring some new data
or
2) making the switch over from matlab or some other numerical analysis
framework.
In general, if you're doing some serious work -- especially work that

Claus,
I think you are looking for something in

Claus,
I agree with Sterling that the colors api page has a great deal of useful
info. However, as another solution to your problem, keep in mind that the
predefined colormaps contained in matplotlib.pyplot.cm return color tuples
when called with a float between 0 and 1. To illustrate with an exte

You can read excel files with the xlrd module : http://www.python-excel.org/
However, you may want to simply read your exported CSV files.
