[Qgis-user] Label using $area and decimals Master 31

[Lene Fischer]

Hi Larry
The decimal funcion works fine -  if I only choose the $area function.
But when I add another field or 'text' the number of decimals expand.

Hello
In Master I´m trying to set a label with the function $area. This works fine.
But I´m trying to use the formatting for numbers with only 1 decimal -  no succes.

Hmm. I just tried setting the expression to $area and using the 'Formatted numbers' option for the layer: worked. I also used just an expression:


format_number( $area, 3)


and that worked too, even where the area result was a whole integer, i.e. label was 12.000. I tested with precision of '1' and both worked fine. Can you share the data, even if it is just a file containing the individual feature that is not labeling properly?


It works fine if I use a coloumn containing the area.
But this is not a solution because the $area is not dynamic in the coloum of the attribut table.

Secondly - how do I activate the functions in the Labeltoolbar -ex Move or Show/Hide

New documentation for labeling canvas map tools is forthcoming. For now, you can reference:
