Yep I've seen that thanks but I can't get it to work. I don't have much experience with matplotlib or programming in general.
I just want to get a contour plot of two numpy arrays.
When I call plt.contour on my data I get "input must be a 2D array"
An example of one of my arrays:
array([ 2.08800006, 2.29400015, 2.00400019, 1.88000011, 2.0480001 ,
2.16800022, 2.0480001 , 1.88200009, 1.95800006, 2.00200009,
2.02800012, 1.81200004, 1.95000005, 1.96200013, 1.95200014,
1.99800014, 2.07000017, 1.88200009, 1.98400009, 2.13400006,
2.11400008, 1.89400005, 2.05000019, 2.01999998, 2.03400016,
2.16600013, 2.00999999, 1.86200011, 2.19800019, 2.01200008], dtype=float32)
How do I get the above array in to the right format for a contour plot?
Thanks,
Jamie
