Inlcuding a field on the y-axis to add unit information

Currently in Spotfire, you can either change the number format of the value axis, or change the name of the variables of the value axis to include unit information.
However, the first option adds the unit on all labels of the y-axis. This sometimes leads to nearly unreadable small labels, especially when the units are long.

The second option only works if you do not choose more than 3 variables (otherwise the information collapses and does not all the variable names anymore). As it is sometimes needed to add several values on the axis (mean, meadian, standard deviation, etc.), the information about the unit vanishes.

An addional field or option to include the unit of an axis in one place (at best right next to the variable names) is therefore required.

Thanks for consideration.
