Hello All:

I have data for 2 fiscal years by zip code as well as the value for the difference between the 2 years (FY 2-FY1).  In some cases, the resulting value is a negative number.  Can anyone suggest a good way to symbolize negative values in a choropleth map?  Is there a color ramp that works for this?  Thanks.
