Hi, My OS is Mac OS X Lion, and the version of matplotlib is 1.2.0 from macport.
Now I have an 2d array a=array([[ 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. ], [ 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. ], [ 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. ], [ 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. ], [ 0. , 0. , 0. , 0. , 0. , 6.40312424, 19.02629759, 9.8488578 , 12.16552506, 14. , 0. , 37.01351105], [ 0. , 0. , 0. , 0. , 6.40312424, 4.24264069, 1.41421356, 8.54400375, 4.47213595, 31.25699922, 0. , 25.70992026], [ 0. , 0. , 0. , 0. , 19.02629759, 1.41421356, 17.2626765 , 31.32091953, 24.18677324, 43.829214 , 0. , 55.14526272], [ 0. , 0. , 0. , 0. , 9.8488578 , 8.54400375, 31.32091953, 35.51056181, 40.81666326, 57.27128425, 0. , 84.62860037], [ 0. , 0. , 0. , 0. , 12.16552506, 4.47213595, 24.18677324, 40.81666326, 43.65775991, 74.24957912, 0. , 112.0044642 ], [ 0. , 0. , 0. , 0. , 14. , 31.25699922, 43.829214 , 57.27128425, 74.24957912, 0. , 0. , 0. ], [ 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. , 0. ], [ 0. , 0. , 0. , 0. , 37.01351105, 25.70992026, 55.14526272, 84.62860037, 112.0044642 , 0. , 0. , 0. ]]) first I plot it (in ipython notebook) using: coord_max=12 fig = plt.figure() ax = fig.gca(projection='3d') x,y=np.meshgrid(np.arange(coord_max),np.arange(coord_max)) ax.plot_wireframe(x,y,a) and the plot looks fine. but if I use plot_surface instead, the plot looks very wrong: the plot is zero everywhere except on the boundaries. ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
