Issues with Tricontourf and CubicTriInterpolator

Hey,

I am having issues with some code which keeps coming up with an error. I am creating a river erosion simulator with matplotlib embedded into tkinter. The error message is attached below. I believe this is due to only an array being foind, not a 2D, but I am not so sure. I can share the code below which I believe to be causing the problem.

I would appreciate any help, as this is my first time using Matplotlib.

Code:
def generatepoints(x, y, point1, point2):
squareroot1 = np.sqrt((point1[0] - x)**2 + (point1[1] - y)**2)#cannot chang
#e the **2
arctangent1 = np.arctan2(point1[0] - x, point1[1] - y)
squareroot2 = np.sqrt((x - point2[0])**2 + (y -point2[1])**2)
arctangent2 = np.arctan2(x - point2[0], y - point2[1])
z = -(2 * (np.exp((squareroot1 / 5)2) - 1) * 30. * np.cos(7. * arctangent1) +
(np.exp((squareroot2 / 5)2) - 1) * 30. * np.cos(11. * arctangent2) +
0.7 * (x
2 + y
2))
return (np.max(z) - z) / (np.max(z) - np.min(z))#normalisation of the values error related to here?

no_of_angles = 100 #smoothed out edge, non-clunky
whitecircle = 0 #removed unnecesary white circle in the middle

angles = np.linspace(0, 2 * np.pi, no_of_angles, endpoint=False)
angles = np.repeat(angles[…, np.newaxis], radiusofcircle, axis=1)
angles[:, 1::2] += np.pi / no_of_angles #this is the grid behind I think?

It looks like you are masking out every single triangle in the triangulation, but it is not possible to be completely sure as your code is missing some information such as `point1`, `point2`, `x2` and `y2`.
