20 maj 2019 · i'm looking for the best way to create a contour plot using a numpy meshgrid. I have excel data in columns simplyfied looking like this: x data values: -3, -2, -1, 0, 1, 2 ,3, -3, -2, -1, 0, 1,...
20 maj 2014 · I have some function defined for a given (x,y) point in 2D that returns a scalar f(x,y). I want to visualize the function f using imshow. x = np.linspace(0,4) y = np.linspace(0,1) X,Y = np.meshgrid(x,y) Z = np.zeros((50,50)) for i in range(50): for j in range(50): Z[i,j] = f(X[i,j],Y[i,j]) fig = plt.figure() plt.imshow(Z,extent=[0,4,1,0]) plt ...
