RE: [darktable-user] Missing Histogram

Hi Rafa,

I’m not sure, so changed the theme and restarted a couple times. Still no histogram. Then, I just started playing with buttons. As it happens, the red, green, and blue color channels were turned off. I discovered that if, and only if, all three color channels are on, then I get the complete histogram, including luminosity. If any of the three color channels are turned off, then I get only the remaining color channels, without luminosity. It is impossible to get luminosity only.

So, the histogram is back, with the limitations described.

Thanks for your input.

HI Patrick,

Did you restarted when changed from theme to theme?

Hi Manuel,

Thank you. I do appreciate your help.

I just now confirmed that I am using a standard theme. In addition, I tried all the other standard themes and nothing restored the histogram. I opened the test images directly from darktable, since another user stated that he was experiencing this when he opened from GIMP.

darktable has been buggy for me since Version 3.4 was introduced. I am not an expert user and have neither the skill nor inclination to fuss with it anymore. I think I will be moving on to something else.

Thanks, again.

Best regards,
Patrick Grewe

Hello Patrick,

I also experienced this behavior some time ago. The reason was that I used a
customized "theme" ("general" tab in the settings) and I assume some CSS styles
changed. However, the problem was fixed after switching to a standard theme,
which was shipped with dt.

Hope this helps,
Manuel.
