Change specific datalabels meeting conditions

[oceanseleven11]

Hi all,

I'd like to display another datalabel value than the one originally shown on the graph.
It would be especially helpful to display the datalabel "Non Disclosed Data" to data that has not been disclosed.
Currently, non disclosed data take the value "0", which may be misleading because we don't know if 0 is the real value or just means that it wasn't disclosed.

Any idea on how to do this in Quickchart? They don't seem to accept "if" functions...

Thanks for the help!
