Histograms
 

Hi,
When I was reviewing the histograms,saw an other graph in bright colour below RGB histogram on my Canon 7 DSLR LCD screen can some one tell me what is it?

If you search for the full review of your camera on dpreview.com, they usually describe all the various interface bells and whistles. You'll need to search by model number (Canon 7 DSLR I can't find).

EDIT:

EOS 7D maybe?

Thank you.
