I'm trying to plot Chebyshev polynolmials using: numpy.polynomial.Chebyshev:
import math
from numpy import *
from numpy import polynomial as pol
from pylab import *
from scipy import *
from scipy import optimize
import warnings
warnings.simplefilter('ignore', np.RankWarning)
test = pol.Chebyshe
I think that you're misusing Chebyshev (do you really only want to give "3"
as a coefficient..which is just the constant function 3), and you have to
evaluate it in order to give matplotlib some x and y data to plot.
from matplotlib import pyplot as plt
import numpy as np
x = np.linspace(-1.0,1.0
No I just want to plot the third Shebitchev polynomial.

Regardless of exactly which polynomial you are after, I've showed you how
to plot a cheb. poly. Can you not work with the code given and plot the
exact variation of polynomial you want?

I am still seeing the error below in matplotlib-1.1.0 - the bug occurs
when the user installs our software to the directory "version1", uses
that installation, then installs "version2" and removes "version1",
which breaks matplotlib because (unlike any other Python module I've
ever used) the absolu
Hi-
I was working off of the example listed at
http://matplotlib.sourceforge.net/examples/pylab_examples/griddata_demo.html,
adapting it to my own data, and encountered the following error on MLAB
1.1.0, Python 2.7.2:
from numpy.random import uniform, seed
from matplotlib.mlab import griddata
Thanks for the report, Ethan,

Confirming, this is a bug. We need to change the matplotlib code,
but I'm not sure how to proceed. I've filed it as the ominously
numbered matplotlib issue #666
