Hi Stefan,
agreed, but a data-defined style does not produce a proper legend either
(at least not in all cases). It will contain lesser items, though.

Hi Bernard
Thanks. If you have a lot of rules for the same style in different scales you
end up with a unreadable legend.

Betreff: Re: [Qgis-user] data defined style with $scale
Hi Stefan,
neither a solution nor an answer but a workaround:
I always use the rule based renderer and set the scale for the rule (I _think_
this may
also be faster)

Hi
I have a question regarding data defined styling. I'm using the $scale
parameter to
define the line width:
CASE
WHEN $scale<= 500.0 THEN 1
WHEN ($scale> 500 AND $scale<= 1000) THEN 0.5 END
I would expect that the line is not drawn with a scale larger than 1000. But it
seems
the line is still drawn. It even draws the line with an ELSE-statement:
CASE
WHEN $scale<= 500.0 THEN 1
WHEN ($scale> 500 AND $scale<= 1000) THEN 0.5 ELSE 0.0 END
It seems that I get my expected result when I use an ELSE value near zero (e.g.
0.0000001).
Is this on purpose? Or is there an error in my statement?
regards
Stefan
