See that blue line going across entire histogram when RGB mode enabled, however if show separate channels blue does not stretch across entire histogram.

Same error in big histogram.

Never used GIMP, but it looks little misleading with that blue line across bottom of histogram.

There doesn't seem to be a uniform approach to using the Y-axis when viewing an individual color channel:

Histogram
- separate
  XnViewMP, ACDSee, Affinity, GIMP, Photoshop (even in Colors mode)
- shared
  darktable, DxO
- not allowed to select individual channel
  CaptureOne, Lightroom, Krita

Tone Curve
- separate
  CaptureOne, Lightroom
- shared
  DxO

I would prefer shared Y-axis OR maybe an option to switch it.
