My incremental spatial autocorrelation graph came out flat. Any ideas as to what I might be doing wrong?

[LetoyniaCoombs]

Any suggestions? explanations?  Thanks.

Can you give us some more detail? What exactly are you autocorrelating? Screenshots of your layer, tool dialog, and graph might be a good start.

Summarize with respect to the help file topic

barring that, rescale the y-axis​

[DanPatterson_Retired]

Well your X axis is all wrong...did you notice that the range is in the order of centimeters and it is hard to tell how the graph was created and what was used to go in it.  I hope these data are in a projected coordinate system and not in decimal degrees, would be a start​

[LetoyniaCoombs]

Yes,  I think that is the problem, but not sure.

The projected coordinate system was WGS_1984_Web_Mecator_Auxillary_Sphere

and the geographic coordinate system was GCS_WGS_1984

[LetoyniaCoombs]

So, the problem is that ArcMap thinks the total area of my map is about .2 meter x .2 meter. instead of 150 square miles.  I know this is probably extremely basic, but how do I change this? I'm a novice.  Thank you.

Hi Letoynia, using the Project tool, you can reproject your data into something fitting. Where in the world is your data located?

[DanPatterson_Retired]

where did you get the data? was the Define projection inadvertently used in place of the Project tool if the ariginal data were in decimal degrees?

[LetoyniaCoombs]

Ok. So it is still a projection problem. I got the layer from Arc GIS

online and never projected it. Thanks again.

Letoynia, be aware that the data from ArcGIS online WILL already have a projection. It is very important that you don't change this projection, except by using the Project tool.
