I try to use an expression to set the margin around a feature in the atlas composer.
In documentation, it's explained that it's better to be a double but a string or integer is accepted as an input.
I use this expression that returns a double:
bounds_height( $geometry )/ bounds_height( geometry( get_feature( 'allin1', 'id_ws_int', attribute( @atlas_feature , 'id_ws_int' ) ))) *100+100
But nothing changes. Tried with
to_int but same result.
Tested in 2.14.12 and 2.18.4
No bug reported found.
