Dear listers,
I wish to thematically map trees by their scientific name and by their
canopy radius.
Currently the data is in the form of circles representing trees. All of
these are uniform in radius.
These have a name and canopy radius fields. When I attempt to colour by
species (individual thematic) and size by radius(using graduated thematic)
I only get the size changing but the colours don't. They do but I can't
merge the two variables.
Any ideas?
Can I resize the existing circles by the canopy field permanently?
And then colour them in a later process.
Cheers and thanks
