Use the Element properties dialog to change element labels and calculate ratios.


By default, Protobi assumes each element corresponds to a data column with the same name as the element's key attribute, and uses that value directly.  But it's possible to override this in many ways.

Access the Advanced properties dialog by pressing on the element icon and choosing "More properties":
