I want to create a clean and simpel report and diagram with:
Exampel:
Total points: 4000 point = 400/ha
Mean (topheight): 6 meters
400 points per/Ha, where 100 are 2meter, 200 are 3meter, and so on..
How do I do this?
Arcgis 10,4, spatial analyst, 3d analsyst.
Attached shapefile of intrest. with polygon border.

Solved! Go to Solution.
OK, to answer myself.
First of all Abdullah Anter was right.
To do what I wanted I needed to understand how Join and Relate really works.
Then just add fields and calculate them in modelbuilder as desired.
1. Join by spatial reference
2. Statistics based on a comon field attribute ex. "ObjectID" to get them to correspond to eachother.
3. Join Field from the statistics to the polygon.
4. Then add fields an do the nesseserry calculations.
So what have you tried so far? What form of report is needed? Are you adept at scripting?
Maybe the following links will be helpful:

Hi Dan.
I hvent really tryed anyting aoccessfull..
Near tool on the point with the same point to get spacing between, this is also an factor that would be intressting, but not my focus right now.
I had a quick lock at reports in the attribute tabel, but that dosent really give me what i want.
Tryed avrage nearest naighbor report, but I diddent relly figure ut what I got back in that in the report.
Scripting is'nt relly my thing, quite good at model builder..
Gonna have a lock at the links Anter.
but to be abel to just print an paper or PDF would be the ting...

Use Spatial Join Tool Spatial Join—Help | ArcGIS Desktop , to know what each point fill inside which polygon . you will get that with attached attribute.
Then Use Summary Statistics tool Summary Statistics—Help | ArcGIS Desktop using the attached field that relate to polygon name or number.and make your statistics analysis for.
Thanks Abdullah Anter.
Not really what I thought to do... But its a step atleast to find the height distrubution that does the trick. But I leave that for now.
I have points for all polygons.
I want to do thease calculations and add the results to each polygon so that you easly can use the "info" tool to get this:
Area - This is alredy in the polygon.
Sum of points within each polygon
Sum of points within each polygon / (devided) by Area
Mean value of points within each polygon
Avrage spacing of points: √10000/(Sum of points within each polygon / (devided) by Area)
Not easy to understand how to really do this, peferly I would like to use modelbuilder so i can add this to the other analasys where i got this data from.
In this case the polygon feature only has unike field value in "OBJECTID", after spatial join "OBJECTID_1".
