How to reflect more than one class in the styling
I often would like to reflect more than one class in the styling - such as a quantity or size (very big/big/small/etc) and a time of year say.
I often see this on layers using, say, colours for one class and different shaped little dots/squares/stars for the other. Or even different sized dots for one class and different colours for the other. Is this something others would welcome?
Can anyone think of a workround?
