In my example, I have several cross lines on a channel. I want to make Profile sections of them. This can easily be done by creating a Profile graph of the 3D lines.
Though for display in the legend, the line is automatically taking the OBJECTID/FEATUREID/OID. It would be more user friendly to give the option to use 1 or more attribute values for the reference. In my case: I would like to use the Chainage value and the colour.
