Description
A fishnet mesh was placed over the points and the number of points falling within each fishnet square was counted. All of the counts were exactly the same and this tool requires variation in the values being analyzed.
Solution
Try an alternative Incident Aggregation Method option, provide a feature class for the Bounding Polygons Defining Where Incidents Are Possible parameter, provide a Polygons For Aggregating Incidents Into Counts value, or specify an Analysis Field value.
