Did the permissions are set correctly? Do you see anything on the JS console?
I started modifying my data and layout settings, removing all my options one line at a time, to see what was causing this. It turns out that if you have “hovermode” set to false, in your layout options, then it won’t trigger on-click events. So hovermode must be set to true! (which is the default – I had it changed)
Please have a look at the sample project in the release section of the Chart repository.
I hope this will help you out https://github.com/mendixlabs/charts/releases
