I i have tree lists of values
list x of 100... values
list y of 100.. values
list mag of 100.. values
list x and y are coordiantes of points
and list Mag is magnitude of something at that point
how can i plot this quantities using pcolor
from __future__ import division
from matplotlib.patches import Patch
from pylab import *
def func3(x,y):
return (1- x/2 + x**5 + y**3)*exp(-x**2-y**2)
# make these smaller to increase the resolution
dx, dy = 0.5, 0.5
X = arange(-3.0, 3.0001, dx)
Y = arange(-3.0, 3.0001, dy)
Mag= X**2+Y**2
pcolor(X, Y, Mag, shading='flat')
colorbar()
axis([-3,3,-3,3])
savefig('pcolor_demo')
show()
