[Matplotlib-users] surface without lines + circular domain

[Diego Avesani]

Dear all,
I have two problems.

1) I would like to plot a 3D surface, but without lines.

2) I would like to plot the surface on a circular domain.

I mean, this is a piece of my code

X = np.arange(0, 1, 0.05)

Y = np.arange(0, 1, 0.05)

X, Y = np.meshgrid(X, Y)

R = np.sqrt(X**2 + Y**2)

Z = np.sin(R)

ax.plot_surface(X, Y, Z, rstride=10, cstride=10, alpha=0.3)


The domain is therefore a square, I would like to have a circular domain.


Thanks a lot




Diego

Hi, Diego

1) use the linewidth=0 kwarg to plot_surface (e.g. see
http://matplotlib.org/examples/mplot3d/surface3d_demo.html)
2) Define your mesh by r, theta, then convert to x, y (e.g. see
