I work with this field (in categorized style):
I try to find how can I sort the "value" column (in the style properties) by ascending numerical order. In the attribute table "value" is "YEUD" field:
"YEUD" field id numerical field:
The problem is when I click on "value" name, it sorts the field not the way I am seeking.
I read Why are numeric values in attribute table not sorted correctly? and my version is earlier, and also I don't want to update my QGIS version.
