Dark default chart color?

Setup, Configuration and Use Beginners

Just noticed in the HTML source code of my openhab web, that there seems to be some possibiltiy to influence the appearance of default charts:

<img src="/chart?groups=gInnenTemp&amp;period=D&amp;service=rrd4j&amp;theme=bright&amp;t=1517612007354">

When I replace the “bright” by “dark” in the console of my browser, then a dark chart appears. WOW!
The question is: Where can I change this in my config - and is there a way to change the apperance of BasicUI (e.g. by a custom CSS) in general?

Here’s what the dark theme looks like:
2018-02-02 23_57_26-Innen 22,8 °C
Are there others as well?

it depends on UI. The Android app offers 5 themes and Basic UI only 2.
For Basic UI, you can select the theme with Paper UI: configure -> services -> UI -> Basic UI.

Thank you, I’m using OH now for two years - but I never noticed there’s a “theme” option for the BasicUI…LOL

I get exactly the same chart in black, but without aqny change. I only made a snapshot update to #1220 and now my charts don´t work very well.

They are much smaller than before. The habdroid charts locks ugly, like in your screenshot, some kind of ms-dos style. Before the updte they were white and more beautiful.

Charts in basic ui are much smaller now. When i have many items showing, then i can´t see anything of the chart, because of the big description window.

Was there a change in the code?

I made some charts-changes in a charts.cfg inside service-folder of openhab. It seems, that this is no longer supported???
