I have a GTK application with the code
thisline = event.artist
xdata, ydata = thisline.get_data()
ind = event.ind
print 'on pick line:', zip(xdata[ind], ydata[ind])
cid = fig.canvas.mpl_connect('pick_event', on_pick)
but the routine never gets called when I click the left mouse button.
Instead, the FigureCanvas "pick" method is called.
What am I doing wrong??
