Hey @Andy_i and @louisadekoya,
I think this likely falls under the same issue as the thread below… Andy, Chart Tools also uses Moment.js to handle date based data. So we are probably seeing a clash as both plugin scripts make a grab for the Moment.js library. Do you see any errors in your browser’s console? (Chrome: Right-click > Inspect > Console)
Louis, maybe worth us getting some momentum behind that thread and logging bug reports. Would also be interesting to see what happens when only one of the plugins calls the library - we could setup a test on that if you like?
