It was just a way to swtup a demonstration since I dont have your data. Use your data instead of my ones() and zeros(). Also, it would be more useful to post your latest version of your code that is causing problems so that we can double-check it, rather than guessing what the problem is. Cheers!

Re: [Matplotlib-users] Size of array elements when using Axes3D.plot_wireframe(X, Y, Z, *args, **kwargs)
I tested it out and it does change all the values to ones and zeros. Is there a way to broadcast and keep the original values that were in the arrays?

Re: [Matplotlib-users] Size of array elements when using Axes3D.plot_wireframe(X, Y, Z, *args, **kwargs)
Wouldn't X= np.ones((1, 45)) Y= np.zeros((32, 1)) change the existing values of the elements to ones and zeros?

It does not perform any broadcasting (which I consider to be a bug). Until it is fixed, you will have to do the broadcasting yourself: X= np.ones((1, 45)) Y= np.zeros((32, 1)) x, y = np.broadcast_arrays(X, Y) Which produces x and y with the same shapes, and their values duplicated in the direction the array was "expanded". Pass those into plot_wireframe().

Re: [Matplotlib-users] Size of array elements when using Axes3D.plot_wireframe(X, Y, Z, *args, **kwargs)
Okay thank you! The Matlab code I am basing this on takes arrays of different shapes with different sized elements ie x = 1 512 y = 101 1 and I guess automatically makes the the same shape. Can you point me in the direction of documentation that will explain how I can do this in Python?
