<p dir="ltr">It's not currently possible unless you write a python function to do this.</p>
<p dir="ltr">I've been pondering this week about allowing items to access the variables from another item but need to think this through more.</p>
<p dir="ltr">My (current) use case:<br>
- working on a map of a train line which consists of three vertical panels covering different parts of the line<br>
- certain elements (like label buffers) in the map style use a @background_color variable to data define their color<br>
- each map item in the composition has its own @background_color variable set so that this color represents a good background color for the visible content within that panel<br>
- I want to style things like North arrows to reuse the @background_color variable from the map item they are associated with.</p>
