[Digikam-users] Cannot find the "red marker" to display the luminosity in the histogram (v. 4.13.0)

[Michael Cantinotti]

Hi,

I am a new Digikam user and learning to master the multiple options of this wonderful photo editing software. In the documentation (https://docs.kde.org/trunk5/en/extragear-graphics/digikam/photographic-editing.html), there is a reference to a "red marker" ("The target photo preview has a red marker available. If you place this marker somewhere in the image, a corresponding vertical bar will be drawn in the histogram indicating the color level value in the current channel selected."

However, this feature does not appear in my version of Digikam (4.13.0 Using KDE Development Platform 4.14.10, with OpenSuse 42.1). 

Am I missing something ?In order to adjust the local luminosity or contrast of a photo, this feature would be very useful.
