I have a multypolygon-shapefile of government districts in Germany with two columns, "population density" and "yesno":
The first has integer the second one Boolean values.
I have already colored the map using the population density values (
Now I'd like to use the second column (yesno) for symbology as well.
I want to put one of two symbols (one for
true and one for
false) on every government district.
I know how to use icons for points, but not for polygons.
And I know how to color based on one column, but not two for the same layer.
How can I use an icon for a polygon without losing the earlier classification?
