Description Matthew Woehlke 2012-06-20 19:22:58 UTC 
Fixed vertical scale does not always work. Sometimes, when the system is under load, points appear in the graphs with obviously bogus values and the scale switches from 0% - 100% to 0% - 1e+18%.

Reproducible: Sometimes

Steps to Reproduce:
1. Have ksysguard running, on tab with CPU monitors
2. Do something that runs up the system load (e.g. build kdelibs with -j<many>)

Actual Results:  
Vertical span for some graphs switches to some absurd range.

Expected Results:  
Graph vertical span stays fixed at 0% - 100%.

tab that is experiencing the problem

I'm attaching the saved tab with the graphs for which I'm seeing the problem (expects system with >= 8 CPU's). Usually I'll see 2-3 of the middle row and sometimes 1-2 of the bottom row develop 'spikes' at the same time. I don't know if I've seen any of the graphs in the top row with the problem.

If I catch it again, will try to attach a screen shot also.

...apparently high system load is not required.
