Can I add a new category to an existing layer?
I am trying to market a product only in affluent communities. I have used the layer for "median net worth U.S." which color codes all districts with median household net worth over 200K in the same color. My project would be infinitely easier if I could make that dark green "200K-500K", have another color "500K-1,000,000" and one last color for "1,000,001" as this seems to be the maximum value. Can I do this, and, if so, how?
