Bug ID: 437310
Summary: System monitor does not allow for negative values in
ring charts
Product: plasma-systemmonitor
Version: 5.21.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general

See the Rate chart
SUMMARY
I've added a ring chart for my battery's chargin rate, but there's no way of
mapping it to also negative values.
STEPS TO REPRODUCE
1. add a ring chart for a sensor that can read negative values
2. set the right domain for the sensor or either leave auto
3. wait for negative values
OBSERVED RESULT
ring starts showing a very casual behavior, not even linear wrt values.
EXPECTED RESULT
on a very basic level, it should not matter whether readings are negatively or
positively valued. once a domain is entered, graph should divide currently set
angular domain by sensor domain length, and add the lowest bound as an offset.
Or even better, it should recognize signed domains and have the ring go
clockwise for positive values and ccwise for negative ones, starting from 0.
