I'm working in QGIS, formatting maps in their layout view. I'd like to swiftly and accurately make >50 nearly identical maps using a single layer feature with a large attribute file. Each map would be the same map, except for the field (column of attribute table) whose data is being symbolized in the map layout.
I'd like for the name of the field to be automatically updated and displayed on the map in a label box in layout view (or some analogous text display).
It appears inserting an expression into the label item is the answer to my dilemma but there don't appear to be any expressions which return the name of the field being symbolized within the layer being symbolized. Is this correct?
I have access to ArcGIS desktop and online, should I switch to their programs for this niche functionality? (I'd prefer not if possible haha)
