[QGIS-ZA-user] QGIS Legend Problem

Mon Jul 17 13:11:07 PDT 2017

Hi, Immo

I experience the same behaviour you describe...I am able to get the 
colours to display correctly on the map (using data-defined override and 
referring to the "colour" column) but cannot get the legend to show the 
correct colours without manually editing the legend. I tried on both 
QGIS 2.14.16 on Ubuntu 16.04 and QGIS 2.18.10 on Widows 7. Looks like 
this issue is a known one - see here:

https://issues.qgis.org/issues/11491

Best work-around for the moment, if it is a dataset you use a lot, seems 
to be to manually sort the legend out and then save the style for future 
use in other projects.

Perhaps you should add this to the feature requests for QGIS??

Dean
