SUMMARY I think all graphing functions should use a y-axis set to the max speed of the device/channel. That way, we could instantly see the percent of utilization. I am looking at Network speed on my laptop, which only uses Wi-Fi, and the graph y axis is set at lower than full speed of the channel. It looks like quite a bit of network traffic, but I think it's just heartbeat traffic. If the y axis was set at the maximum speed of the wi-fi link, we would see how insignificant the network traffic was/is. SOFTWARE/OS VERSIONS Linux/KDE Plasma: debian12 (available in About System) KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION I think all graphing functions should use a y-axis set to the max speed of the device/channel. That way, we could instantly see the percent of utilization. BTW, I love KDE widgets, including this one. I set my desktop background to black, and placed widgets for Individual Core Usage, Network speed, and Hard Disk Activity, making my desktop a dashboard showing what my computer is doing. Very useful.
I'm afraid this is intentional as-is. If we scaled the graph according to the max value, 99% of the time you'd see practically no activity because the speeds there would be too small.
Additionally, we don't really have proper information on the maximum speed of a connection. We only know the link speed, which may not reflect the internet speed. It's quite common to have 1 Gbps link speed for wired connections these days, while the internet speed is often less.
