When loading a map in the print composer I always click on the main area where the map displays, then click on 'set to map canvas extent'. Then I adjust the scale as I need. This is all fine.
How do I pick up the scale (e.g. 4000) and have this value automatically inserted into a different part of the printing template as follows?
Scale 1:4000 @ A3
At the moment I have to type the scale by hand every time.
