Perhaps you could provide further details?
If a zip code has a closed deal, can it also have a lead?
E.g. Zip code A has 5 leads and 2 closed deals. What would you want the shade to be and what would you want the marker to be?
Or is it either/or. I.e. Zip code A either has a lead or is closed.
A sample data set would be ideal.
I unfortunately do not have a data set I am allowed to post.
A closed deal will always lie in the same zipcode as a lead, but a lead will not necessarily have a closed deal. There are many more leads than closed deals. My intentions are to fill the map for leads, and then overlay it with dots for the closed deals. I hope that provides enough info.
