Will do! Thanks you so much for taking the time to answer me.
After your response, I tried moving a few things around and use different dimensions and groupings.
(I was already using (.dimension ndx) and (.group all))
Nothing worked.
That is until I switched the order of re-applying the filters and adding the new data.
I did the same thing on your fiddle and it still works.
For some reason the order matters on my charts but not on the example provided.

Ok, I think I found the problem.
One of the charts has a on-filtered hook to focus some followers charts.
Turns out that everything is fine until I use the .focus method.
When I use .focus, I must make sure that filters are applied before adding the new data or the dataCount will be wrong.
