Hi!

Thanks, for your reply. I don't have a 1000 unique features, I have around
20 features with a attribute (value) ranging from 0 to 1000. I want to show
the features with attribute value 0-99 in one colour and the ones with
attribute values 100-1000 in another colour. And be able to toggle between
showing  just one of the groups  on the map, or both groups together. So
there are no unique values.
