I have a grouped bar + line card, which contains one field for bar and one field for the line. I'd like to have only one Y axis on the left. Is it possible?
you can do it this way
1) build the card as you normaly do
2)under chart properties > general , check the boxes
a) Sync Value Scales
b) Hide Second Scale
c) and just to be in the safe side the box for Sync Zero Line
that should do it.
