python - Matplotlib - tooltips on mouse hover -

here 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 error

attributeerror: 'axessubplot' object has no attribute 'canvas'

edit: fig of type axessubplot, , instantiated this

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

what easiest way add together tooltips on scatterplot? please note want maintain current framework, calling fig.scatter, these scatters overlaid on existing figure.

subplot2grid() returns axes object, utilize it's figure attribute figure object:

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