Interact.ipynb raises exception

[fkromer]

When I execute the cells of the Interact.ipynb I get an exception after executing the last cell:

Same here. Does someone have a solution for this?

[StepanSmirnov]

I solved this. Just add .data[0] to add_scatter()

[ljburtz]

I was coming here to report the same fix! this fix works. please merge this!

Thank you @StepanSmirnov. It works.
BTW what does it mean: ".data[0]"?
