Cannot "Create Graph" in ArcMap 10.1

[EliMelaas]

I would like to create a histogram of a raster layer using the Graph Wizard in ArcGIS 10.1. However, when I pull down the "View" tab and click "Graphs", the "Create Graph..." option is not highlighted. Is there some option in ArcMap that I need to change in order to the Graph Wizard to become functional?

Hello!

Does the raster you are trying to use have attribute table? If it is a floating point raster, it will not have the attribute table and the graph option is not active. If your raster is a floating point, convert it to an integer raster using the INT tool in Spatial/3D Analyst. If you raster is already an integer raster and does not have attribute table, run the Build Raster Attribute Table. Once you have attribute table for your raster, Create Graph option should become active.

Other option you have is creating Histogram of a raster layer using the Spatial Analyst toolbar.

Hope this helps!
