SUMMARY All the resource consumption widgets show a filling circular bar with the current usage in the last second. When monitoring resource usage, one usually wants to see a short history of how this usage has changed over time. Unofficial widgets such as the one below can do it and fit nicely within a plasma panel: https://github.com/kotelnik/plasma-applet-resources-monitor But would be nice if the built-in widgets could also show a short history of what happened in the last couple seconds (especially since now plasma has deprecated the monitoring library that the other widgets relied upon). In short, it would require changing from a filling cirucular bar to a vertically-rotating horizontal bar like the ones that used to show up in ksysguard.
There's plenty of users that want to only see the current state and don't require history. That said, you can change the display style on the "Appearance" tab of the widget configuration. The line chart display style will do exactly what you request here.

That makes it show the information **once it is clicked**, and not in aggregate like the one in the link does.
