I created two raster datasets from the same world view 2 image. One dataset is NDVI, the other is a normalized surface water index (NDSWI). I would like to create a scatter plot for a pixel by pixel comparison.
I've seen a few options for how to do this but they involve running a combination function in raster calculator which only allows for integers. I need the float data. I also have access to ENVI if there is a way to do it in that software.
Running ArcGIS 10.2 and ENVI 4.4
