Bug ID: 432115
Summary: Graph updates are choppy
Product: plasma-systemmonitor
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: gudv...@gmail.com
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
SUMMARY
Both plasma-systemmonitor and ksysguard update graphs every "tick" so it make
them look choppy rather than smoothly progressing.
Right now plasma-systemmonitor do not even have settings to set "tick" period.
It may be possible to update graphs in real time with certain speed but update
value only at these "ticks" by either buffering value on previous tick and use
interpolation for values in between or update continuously using current value.
First approach will lag one tick behind. Or even more, depending on how smooth
graphs should be. But it will produce wavy graphs.
Second approach will probably look a little staircasy but will represent real
values rather than interpolated ones.
I personally lean to first one since purpose of graphs in system monitor is not
to determine if your system had 88.9% cpu load 0.5 or 1.0 seconds ago but to
see general system or process behaviour.
