Bug in Interactive Bar chart?

Is it possible that the interactive bar chart node has a bug?

I’m plotting the returned quantities from several customer (category) filtered by year.

Everythings is ok if I select a view where all years are selected, if I select the data visualization on the interactive bar chart by single year, there are no corrispondence between the category on the x-axis and the real Bar data: i.e. on the x-axis in corrispondence of the customer “A” there is the bar corresponding to returned quantitie in the selected year of customer “D”.

Is it a bug or a my error?

Many thanks for any kind explanation.

Regards
