When I open the metadata in Erdas Imagine 2016 of a raster file (I tried several different raster files) the histogram at the histogram button stays grey. I already tried to change the setting of NAs and select different bands in the multispectral options but no help.
I doubt, there is a problem with Erdas Imagine, as the histograms worked fine on one day when I had access to a computer with Erdas Imagine 2015. Unfortunately, I cannot get access to this computer anymore.
I tried to reach the support team of Erdas (Hexagon Geospatial Support Portal) but was not successful.
