Hello All,
i'm plotting a 3d colored surface using a 4D array that comes from a .mat file
using this code :
import scipy.io as sio
import pylab as p
import mpl_toolkits.mplot3d.axes3d as p3
def loadmatfile(matfile):
matdata = sio.loadmat(matfile)
return matdata
def plot3dcolor(matfile):
data = loadmatfile(matfile)
x = data['X_depth']
y = data['Y_depth']
z = -data['Z_depth']
c = data['Z_compl']
fig=p.figure()
ax = p3.Axes3D(fig)
cmap = p.get_cmap('jet')
norm = p.Normalize(c.min(), c.max())
colors = cmap(norm(c))
ax.plot_surface(x, y, z, rstride=10, cstride=10, facecolors=colors)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
print x,y
p.show()
matfile = '/Users/epy/Desktop/complexity_depth_grid1.mat'
plot3dcolor(matfile)
the results is nice :

but as you can see, the mouse cursor shows me the x,y values (they are
longitude and latitude)
but on the axis i have them starting from 0 ...
how can i change the axis to display the lon-lat coordinates ?
thanks a lot for any help!
Massimo.
