Filtr and Total

Good afternoon,

I have this graph where we can see the percentage of project sponsored by each sponsor  for some medical areas and the total percentage for one sponsor.

If we want we can filtrate to see only one sponsor and in that case if would like not to see the total wich is obviously 100% and is not really revelant. (Pictures below)

If you know how to hide total when filtrate i would be pleased to hear your answer.

Thanks you for reading me,

Victor
