I always wondered if there's a way to represent using an array of various icons multiple attributes of a single layer containing point features. For example, think about a point feature with these two attributes:
- Primary activity: 1, 2, 3
- Secondary activity: 1, 2, 3
A feature could have values for these attributes like (1,1) or (2,1) the values are qualitative discrete like data, not continuous numerical, let's say something like: 1 commerce, 2 finance, 3 health services.
I would like to represent the point with all the combination of activities in a way their activities icons arrange around or aside the point, not by overlaying separate layers with representation for each one of the activity attributes, because the overlaid icons would not be legible.
Values for attributes can't be represent by color-form combinations, they should be represented with specific icons for the activity.
