Since the developer of Rawnalyze has died and no new updates have been made in a few years, is there another tool that would be similar?
There is another possibility to display a RAW histogram (If you know others please share) that involves two tools: dcraw + Histogrammar
dcraw lets you to convert an unprocessed RAW file into a tiff file, with the -D option
The command I use is: dcraw -v -D -4 -T filename.ext, (where the options mean: verbose, document mode, linear 16 bit, tiff)
Histogrammar is a tool developed by Guillermo Luijk, a contributor on this forum (Gracias Guillermo por tus aportes en este foro y en tu página web),
There is an option to show the RAW histogram provided the tiff file has been processed with the -D option in dcraw
dcraw has been updated recently to support new cameras (as the Nikon D7000). You can find recent compiled versions
here The attached file shows the raw histogram for the same image in Histogrammar and Rawnalize. The scales of the histogram are different, but you can play with the parameters to get a very detailed graph.
