python - Multiple pick events interfering -

i have several data series scattered in figure , want able toggle annotations them. problem is, there 2 pick events triggered (when user clicks on spot within both annotation , dot). "annotation" pick event clears annotation, "dot" pick event puts right back, effect toggle doesn't work.

df = pd.dataframe({'a': np.random.rand(25)*1000,                    'b': np.random.rand(25)*1000,                    'c': np.random.rand(25)})  def handlepick(event):     artist = event.artist     if isinstance(artist, matplotlib.text.annotation):         artist.set_visible(not artist.get_visible())     else:         x = event.mouseevent.xdata         y = event.mouseevent.ydata         if artist.get_label() == 'a':             ann = matplotlib.text.annotation('blue', xy=(x,y), picker=5)         else: # label == 'b'             ann = matplotlib.text.annotation('red', xy=(x,y), picker=5)         plt.gca().add_artist(ann)  plt.figure() plt.scatter(data=df, x='a', y='c', c='blue', s='a', alpha=0.5, picker=5, label='a') plt.scatter(data=df, x='b', y='c', c='red', s='b', alpha=0.5, picker=5, label='b') plt.gcf().canvas.mpl_connect('pick_event', handlepick) plt.show() 

how can separate annotate , dot pick events , tell not annotate if dot has annotation? i'm using labels decide scatter series picked.

thanks much.

you create annotation every scatter point beforehands , set of invisible. click on scatterpoint toggle visibility of respective annotation. click on annotation nothing.
