Hello List,
what is the use of variables in print composer? A map frame has
variables assigned like map_extent_height and _width. But how to make
use of those variables? If I try to place a rectangle around the map
frame using the determined extent variables (plus something), I cannot
use the variables. There is a ‚data defined override‘ section in the
Position and size dialog for rectangles, but when I select ‚variable‘
it tells me that there are no variables, which seems to be nonsense.
Best regards, Uwe
Uwe,
When you select a Data_defined_override in Position and size, pick edit
from the list instead of variable. In the Expression string builder you
will find map_extent_height in the Variables list.

Martin
