Symbol prioritization for a Layer

[Luca Manganelli]

Hi,

I'll try to explain my question:

I have 20 points with 8 features each.
Each feature can have a red, yellow or green circle as symbol.
The symbol order is: view those red first, then yellow and finally green.

I.e:

first point, all features green:   view a green circle.

second point: all features green, but one red: view a red circle.

third point: all features green, some yellow: view a yellow circle.

finally, fourth point: some green, some yellow, one red: view a red circle.


There's any way to do this for ONE LAYER ?
