How can I create a Hot Spot map?

[DominickD_Andrea]

I am trying to take these attached addresses and map them within the polygons from this link: Pennsylvania Spatial Data Access | Data Summary. I want to create a hot spot map where each polygon is color coded to reflect the amount of values counted within that polygon.

Essentially, this is what I want my map to look like. How can I create this? 

I tried spatial joins, but my .csv data doesn't match any of the data in the shape file.

address have to be geocoded, 

I suspect the tutorial would be a good place to start

I have the addresses geocoded, but I can't seem to perform a spatial join. 

[DanPatterson_Retired]

I you have an output featureclass, is it in the same coordinate system as the polygons?

It won't spatial join unless the coordinate system is the same (you will need to use the Project Tool in arctoolbox to finish this)

[DominickD_Andrea]

No, it looks like the polygons are an intptlat, intptlon while my data is on an x,y. Is that what you mean?

[DanPatterson_Retired]

Yes... what coordinate system is the stuff you geocoded?

You might want to assist by stating what coordinate system the dataframe/map was in?

right-click on the layer and check its properties

My addresses are in GCS WGS 1984. 

My polygons are in GCS N.A. 1983.

Then you are ready to roll...

Project—Data Management toolbox | ArcGIS Desktop  in *map and Pro

project the GCS WGS 1984 to the polygon's coordinate system... then spatial join 

[DominickD_Andrea]

Ok, great. I got it to work, and now I can see the join. However, it will only show 3 classes; polygons with 1, 2, or 3 points. Polygons with over 3 aren't being shown on the scale (considered "out of range"), and I can't change the number of classes in the editing tool.
