Unchecking one or more of the values turns off the trace for that value. There are two commands, Equalize and Stretch available from the Colors Menu (sub) Histogram Functions. The Equalize Command will average the traces in the Histogram and should smooth the image. The Stretch Command spreads out the image luminance similar effect as Brightness/Contrast.
