Description Andy Great 2021-02-17 17:36:20 UTC

Created attachment 135773 [details]
video showing line chart of memory usage.

SUMMARY
Every line chart seems start from the left scrolling to the right. Is this intended feature? (see the attached video)

The value of sensor legend stuck at zero until the line reach the right side of the view window. This happen to every type of sensors, CPU, memory, temp, disks, etc. (see video)

STEPS TO REPRODUCE
1. Start system monitor.
2. Look at the line chart with legend with number value.

OBSERVED RESULT
The line chart seems to move too much to the left relative to the viewing windows.
Number value stuck at 0.0 until the line chart reach right side, then it read correct value.

EXPECTED RESULT
I think the line chart should start from the right of the viewing windows, scrolling to the left.

Update: Another openSUSE snapshot was released and I update it. The value of sensor legend now correctly display the value. But the line still more in weird way.

The legend thing was indeed a bug that was fixed.

The fill behavior of the chart is intentional, it was the other way around before.
