I have started using ArcMap 10.6 and need to create a heat map of point counts over the country. I am able to draw the fishnet over a smaller test area. What tool do I need to use to fill in the fishnet squares with graduated colors of point counts? I have tried numerous examples from google but they have not worked. My data set consists of only Lat/Long pairs in a file. I have converted these to shape files.
I attached a small screen cap of what I am trying.
Pro has some nice features, but try joining the tessalation to the points...
Did you try a spacial join?

you have a many to one relationship which you want the join count values for the polygons
what about Density?
If you have the spatial analyst extension and the tessalation is converted to raster first so you can control cell size, and analysis extent and related parameters.
I don't have the pro version. But I do have the spatial analysis add on.
But I need more basic help on this one. I created a tessellation over the whole country (USA). It is very slow.
I used a simple join from tessellation to the longitude field to test out and I can see highlighted hexagrams if I also apply a "Select by Attribute" on the Join shape file. But this is not what I am interested in.
Is there any website/video that can help get me understand steps to get a point count heat map?
Also I have tried PointDensity and Aggregation and these dont seem to take the tessellation as an input field. Also PointDensity has very odd distributions such as -1,307,732.125 -- -1,162,428.556... I know at least the coord projections are the same.
