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.
