Thank you for your questions. I have answered them below.
1 - I think you can see those in the editor, but maybe they are a little hard to find:
Event: ‘Bar is clicked’.
States (these are set when a bar is clicked): ‘Name’, ‘id’, ‘Current progress’, ‘Starting date (text)’ and Ending date (text).
2 - I just published an update (1.1.0) that let you change the view mode dynamically! I also updated the demo page:
3 - The bars on the chart can’t be manipulated. Initially it was the intention to include these features, but they let to a lot of bugs and unexpected behaviour and that’s why they are not included in this version.
Hopefully I answered all your questions.
