Matplotlib - tooltips on mouse hover

Here is what I tried:

def onpick3(event):
        ind = event.ind
        print 'onpick3 scatter:'

fig.scatter(t, p, color='b', zorder=10, label='label', picker=True)
fig.legend(loc=fills_legend_pos[index])
fig.canvas.mpl_connect('pick_event', onpick3)

And the error

AttributeError: 'AxesSubplot' object has no attribute 'canvas'

Edit: fig is of type AxesSubplot, and is instantiated like this

fig = plt.subplot2grid((i, i), (j, 0), rowspan=1, colspan=i)

What is the easiest way to add tooltips on my scatterplot? Please note that I want to keep my current framework, with calling fig.scatter, as these scatters are overlaid on an existing figure.

subplot2grid() returns an Axes object, use it's figure attribute to get the figure object:

import pylab as pl
axes = pl.subplot2grid((2, 2), (0, 0), rowspan=1, colspan=1)
axes.figure.canvas.mpl_connect('pick_event', onpick3)
