How to get properties of picked object in mplot3d (matplotlib + python)?

matplotlib, mplot3d, picker, python

Solution

You can use _offsets3d attribute of event.artist to get the coordinate data, and then use ind to get the picked point:

def onpick(event):
    ind = event.ind[0]
    x, y, z = event.artist._offsets3d
    print x[ind], y[ind], z[ind]

Problem

I plot a series of points using `mplot3d`: ``` import pylab as p import mpl_toolkits.mplot3d.axes3d as p3 fig = p.figure() ax = fig.add_subplot(111, projection='3d') ax.scatter([1], [0], [0], c='r', marker='^', picker=5) ax.scatter([0], [1], [0], c='g', marker='^', picker=5) ax.scatter([0], [0], [1], c='b', marker='^', picker=5) ``` and then I add a picker function: ``` def onpick(event): ind = event.ind print ind fig.canvas.mpl_connect('pick_event', onpick) ``` and finally plot it: ``` p.show() ``` Is there a way of getting the 3D coordinates from the marker I am clicking? So far I can get the index of the point in the list I used at `ax.scatter()`, but that wont cut it as I use `ax.scatter()` many times and this has to be this way (I use different colors for example).
