topic Symbology question in Mapping Questions https://community.esri.com/t5/mapping-questions/symbology-question/m-p/90266#M1064 <HTML><HEAD></HEAD><BODY><P>I'm very new to ArcGIS and would very much appreciate some help with this software. I'm creating a district map based on the prevalence of disease x. I cannot seem to get this right- the prevalence ranges from 80 to 100, and would like there to be 5 classes (80 to 82, 82.1 to 86, 86.1 to 91, 91.1 to 95, and 95.1 to 100). But when I select the Field as District, and Normalization as Prevalence, the gradient fill of each district does not correspond to the prevalence. For some reason I cannot upload the screenshot of what I'm dealing with.</P></BODY></HTML> Sat, 23 Jul 2016 10:31:36 GMT ericnham 2016-07-23T10:31:36Z Symbology question https://community.esri.com/t5/mapping-questions/symbology-question/m-p/90266#M1064 <HTML><HEAD></HEAD><BODY><P>I'm very new to ArcGIS and would very much appreciate some help with this software.
