Re: [Matplotlib-users] plotting a series of 3D points and, picker=True and 3D

2008-01-29 Thread Michael Droettboom 
The axes3d stuff is not currently working on the SVN trunk.  You 
probably want to use 0.91.2 or the v0_91_maint branch in SVN instead.

Cheers,
Mike

 I think scatter3D does what you want:

 from matplotlib import axes3d
 import pylab as pl
 fig = pl.figure()
 ax = axes3d.Axes3D(fig)
 ax.scatter3D(data[:,0],data[:,1],data[:,2])
 ax.set_xlabel('X value')
 ax.set_ylabel('Y value')
 ax.set_zlabel('Z value')
 pl.show()

 You could also change the colour and size of each point based on other
 array values:

 col = ax.scatter3D(data[:,0], data[:,1], data[:,2], c=data[:,3],
 cmap=pl.cm.jet, s=data[:,4])
 cbar = fig.colorbar(col,shrink=0.9,extend='both')
 cbar.ax.set_ylabel('axis 3 data values')

 Pretty nifty.

 Neil

 hello,
 I would like to plot in 3D a dataset organized as 1000 x,y,z points in a
 numpy array, so it would be smthg like
 plot3d(data[:,0],data[:,1],data[:,2]). I looked at the plot3D cookbook
 page, but it all seems to expect some sort of binning on a grid.

 best,
 Johann
