my hardware sensors occasionally fail (maybe once every couple of minutes or so) and ksysguard interprets this as a value of zero and thus changes the displayed scale to have a minimum of zero. 

that means effectively that i can not use the feature of configuring a minimum value for the scale.

Reproducible: Always

Steps to Reproduce:
1) create a new tab
2) add some hardware temperature sensors as line graphs
3) set min/max for the scale (to a reasonable value greater than zero)
4) wait
5) occasionally a nonsensical value of zero will occur
6) the displayed scale will now have a min value of zero


Actual Results:  
7) the displayed min value will be zero until you close/restart ksysguard


Expected Results:  
i _do_ like the fact that ksysguard automatically adjusts the displayed scale if values outside of the configured scale occur. so thanks for how step 6) works!

however it would be nice if ksysguard would at some time return to the configured settings. like this:

7) wait some time until ksysguard forgets that there was a value of zero and then the displayed scale will again be as configured

i assume that it is _normal_ that hardware sensors occasionally do not work.
for example the following command will occasionally fail for me:

root@white:/sys/devices/platform/applesmc.768# while true ; do for (( t=1 ; t < 11 ; ++t )) ; do echo -n "$(cat temp${t}_label)=$(cat temp${t}_input) " ; done ; echo "" ; done

If i am wrong in my assumption that it is normal that sensors fail occasionally then please ignore/close this bug!
