I don't think your data is well-formed. The input X, Y, and Z needs to be
2D with the same shape. I am confused by your x and y data, which you then
pass into meshgrid. To illustrate, meshgrid does this:
for:
x = [1, 2, 3, 4, 5]
y = [1, 2, 3]
then the command:
X, Y = numpy.meshgrid(x, y)
produces (for X):
array([[1, 2, 3, 4, 5],
[1, 2, 3, 4, 5],
[1, 2, 3, 4, 5]])
and (for Y):
array([[1, 1, 1, 1, 1],
[2, 2, 2, 2, 2],
[3, 3, 3, 3, 3]])
Your x and y look like they are flattened versions of these. In addition,
your z doesn't seem to have enough values to fit the domain.
