[QGIS-Developer] How do I define a marker offset with an expression.

[Chris Crook]

Hi All

I am trying to offset a marker (ellipse or simple marker).  I can easily do this by entering values into the Offset x and y fields (eg 20.0, 30.0 mm).

However I haven't figured out how to enter this as an expression.  I have entered an expression as "array(20.0,30.0)" but the symbol remains at its unadjusted offset.

Have I got the expression syntax entered incorrectly?

Thanks
Chris
