I'm trying to create a heat map in ArcMap 10.4.1. I've already selected a base map, created a shapefile out of my data points, and overlaid that shape onto the map. Next I go tools -> point density. I set Input Point Features to my shapefile. I click on environments, then Raster Analysis, and then I set mask to my shapefile. Finally I go to Processing Extent and set the boundaries I want using another layer.
After all of this, I get the entire area filled in with one solid uniform color. The densities of the points are not reflected at all. Also, when I look at my table of contents, I see that the ranges for every single color are the same.
Can anyone tell me what I might be doing wrong?
