Created attachment 145127 [details] Screenshot of graphs with different themes SUMMARY The graphs of Charge Percentage and Energy Consumption are not very readable with themes that have dark backgrounds STEPS TO REPRODUCE 1. Switch global theme or global colors to Breeze Dark or any theme with a dark background. 2. Open Energy in the Info Center 3. Try to read the graph. OBSERVED RESULT The red line against the dark background is not very readable, and the red area beneath is almost unnoticeable. See attachment EXPECTED RESULT The graph line pops out from the background. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux running kernel 5.15.12-arch1-1 KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.89.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Maybe make the graph color dependent on the background color of the current theme?
I noticed that the screenshot of the graphs is quite readable on my phone, so I guess the problem is partly because of my laptop screen. But still, it wouldn't hurt to make the graphs more readable.
In my case while the graph line itself plus the area under it is visible enough the grid lines in the background are near invisible with Breeze Dark, which makes it hard for me to check whether power consumption has stayed under 10W for example.
Fixed by Prajna Sariputra with https://invent.kde.org/plasma/kinfocenter/-/commit/174cd66a5edab2adb4a93e127e4ee8ad8b443381 in Plasma 5.27.!
