I am using a trial version of ArcGIS Pro. I have an attribute table which I have imported as a shp. file (contains disease rates over various intervals and regional boundaries) using the "Add data to map" function in the toolbar. I then right click the shape file and click "symbology" using the "graduated colour." I then select the field I want to display and appropriate scale. Some fields in my attribute display exactly as I they should. However, I can't get for of the fields (columns) to display on my map. Both the data from the shp. file and topographic map disappear. I can't seem to figure out why. Any suggestions or things to check would be much appreciated. Thanks!
