Well that's two of you.

I can't replicate this though, so I have no idea why it's happening.

If you both list everything relevant about your installs (versions, dark/light variant, etc), something might be obvious.

I am seeing a similar issue. I played around with changing the colors and no matter what I set, I always get the same transparent graph with black text regardless of what color options are set. However, when I run the command on the CLI I get an image that looks like what I would expect.

I have no idea then.

Theme "mode" is set in index.php:

    if (!isset($_SESSION['mode']) || $_SESSION['mode'] != $config['themes'][$_SESSION['theme']]['type']) {
        $_SESSION['mode'] = $config['themes'][$_SESSION['theme']]['type'];
    }

I can't see a lot of scope for that not to work, especially since no one else has really reported it.

Do you have any local modifications?

What does "svn status" show?

Hi Adam,

I'm referring to the datapoint name/value text in graphs, in case the descriptor 'legend' is being overloaded here and means something different to you, than to me ;)

see attached imagery for examples ;) 

is there something else I should check here? [yes, I know py2 is icky. working with tkl to get an updated observium appliance into their pipeline, as this one's somewhat old....



hope yer doing awesomely.

Howdy, all!


is there some voodoo necessary to coerce observium to generate graphs with textual legends that aren't black when dark mode is active? it's kinda hard to view black text on dark blue backgrounds :)

I don't see an obvious knob for this, but it's entirely possible I'm just missing the "legend text color" or "make graph text legible in dark mode" or "learn to read" button somewhere :)
