Shortcut for a dot on plots in matplotlib

Question

So this is a question about a hosted solution. I tried to put some data labels on the dots in the matplotlib scatterplot that I have. I tried to imitate the solution here:

Is there a matplotlib equivalent of datacursormode matlab?

inside def __call__(self, event): I get a failure on the line:

 xdata, ydata = event.artist.get_data() AttributeError: 'CircleCollection' object has no attribute 'get_data' 

Looking at the docs here: http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.artist

I do not see the get_data () method for Artist. Is this something that is out of date or is something missing? If it was, does anyone know how else to get the equivalent call?

Answer 1

If you look at the rest of the code in __call__ , you will see that xdata and ydata never used. You can just delete the line

 xdata, ydata = event.artist.get_data() 

and the rest of Joe's beautiful code works great.
