Interactive graphs with kivy

[ToshiEAB]

I can display a matplotlib graph on a kivy's widget using kivy-garden's garden.matplotlib. Now I'm trying to make an interactive graph so that, for instance, I can open a file by clicking a specific data point on the graph. The original matplotlib has callback functions for create interactive graphs (see attachment) but these functions seem to be lost after displaying on kivy's widgets. Is there any way to have callback functions on the kivy's widget?

Thanks in advance!

for interactive graphs in kivy, I think my matplotlib widget is much better for this: https://github.com/mp-007/kivy_matplotlib_widget
