Bug ID: 433007
Summary: Line chart data range of maximum 5 digits is
insufficient
Product: plasma-systemmonitor
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: gilles.corem...@gmail.com
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
SUMMARY
The "data range" field for line charts only takes numbers of up to 5 digits.
This is insufficient for things like memory, as memory is measured in KiB but
modern systems can have GiB of memory, requiring more than 5 digit amounts of
KiB to represent. Thus it is impossible to make a nice-looking line graph of
memory usage.
STEPS TO REPRODUCE
1. Create a Line Chart
2. Add an "application memory (KiB)" sensor (or similar)
3. Attempt to set data range to 0 to 16777220 KiB (= 16 GiB)
OBSERVED RESULT
The max of the data range is truncated to 16777 KiB, making the graph
unreadable as the memory usage is always higher than ~16 MiB.
EXPECTED RESULT
The max of the data range is set to the requested amount and a readable graph
results.
SOFTWARE/OS VERSIONS
Linux: 5.10.16-arch1-1
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.79.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
Using the automatic Y range does result in a graph with gigabytes on the axis.
However, the maximum on this graph is about 42 GiB, and as my system only has
16 GiB, this is still an ugly (and difficult to read) graph.
