[Qgis-user] Atlas: Is there a way to synchronize canvas to atlas preview?

[kimaidou]

Hi all

Considering the atlas scale settings, what about being able to use an
expression to define the scale to use feature by feature ? This way we
could use a set of scales instead of choosing only one, and so we can know
in advance how to set the layers properties like labels and style to render
as desired for each scale.
