Re: [Qgis-user] problem with cartographic label placement

Hi Uwe,
I've not attempted to deal with this issue before, but it occurred to me that you might be able to use two labelled layers (duplicates) one locked to each position, using the labelling priority weighting to apply the ranking. the only issue is that in sparse data areas both labels might be drawn, so you may need to ensure that there is sufficient overlap between the two positions to prevent this. 

Cheers,

Andy

Hello Andreas and list,


I am sure I’m not the first one to encounter the problem described 
below. So I would like to ask again. Maybe someone has an idea?


thanks a lot, the solution from Andreas is working.


But the result is not as desired. I was hoping to be able to define a 
ranking of placement alternatives. That is (in case of ‘B,R‘): place 
all the labels at the bottom and only if there is a conflict (overlap) 
with something else place a label at right.



But what I get is: most oft he labels are placed right, even without 
overlap problems (although I put ‘R‘ at the second place of the list). 
And only a few labels are placed at bottom.


However, the overlap problem is solved.

Is there something I could improve?

Thank you and best regards, Uwe

Hi Uwe,


I just tried it. 'B,BR' worked for me. Just don't use quotes before 
and after the separator.


Greetings,

Andreas

    Hello list,

    for cartographic label placement, according to the help docs it
    should be possible to define position priorities in a ranking.

    But when I open the editor and enter a comma separated list like:

    ‘B‘ , ‘BR‘

    I get an error message. Entering just one value it works. But that
    doesn’t make sense because I need at least two values to let the
    label move when it collides with a feature.

    What can be wrong with my input? I use 3.28.

    Thanks a lot for help.

    Uwe
