hello ppl,
hey i hav 3 .dat files... one has 1 column of x coords, another has 1 column
of the same number of y coords and the last .dat file has the same number of
corresponding values of a property[temperature] at those points in 1
column.... i was wondering how i cud make a contour of this data with the
last .dat file being the z-values... i hav written the following code(
saf2.py)[mind u ppl am a newbie @ python+matplotlib]...
from pylab import *
x = load('xcord2.dat')
y = load('ycord2.dat')
X, Y = meshgrid(x, y)
Z = load('output1im.dat')
contour(X,Y,Z)
show()
the following errors crop up:
Traceback (most recent call last):
File "F:\Python25\saf2.py", line 9, in <module>
contour(X,Y,Z)
File "F:\Python25\Lib\site-packages\matplotlib\pylab.py", line 1776, in
contour
ret = gca().contour(*args, **kwargs)
File "F:\Python25\Lib\site-packages\matplotlib\axes.py", line 4674, in
contour
return ContourSet(self, *args, **kwargs)
File "F:\Python25\Lib\site-packages\matplotlib\contour.py", line 429, in
__init__
x, y, z = self._contour_args(*args) # also sets self.levels,
File "F:\Python25\Lib\site-packages\matplotlib\contour.py", line 601, in
_contour_args
x,y,z = self._check_xyz(args[:3])
File "F:\Python25\Lib\site-packages\matplotlib\contour.py", line 577, in
_check_xyz
raise TypeError("Input z must be a 2D array.")
TypeError: Input z must be a 2D array.
wat errors am i making?
