Apparently previously fixed in Plasma 4 (Bug 245762), it has returned in Plasma 5:

I have no Swap partition but a Swap graph is shown anyways (always at zero).

Expected behaviour: Don't show that graph at all.

I registered here to report this.

I read kmi, Dr.Chapatin comments. Fully agree and confirm the bug presence.

Please get rid from that zero-level line of the entire swapping technology turned off.
O level line means availability of swap but not in use for that very moment.
Disabling of all swapping itself should lead to line absence, not zero-line.

Example:
Imagine we have 3 SSDs on the system. One day we removed and sold couple of them. So now we have only 1 SSD connected.
But some utility shows us that we have 3 SSDs but two of them has capacity of 0.
It is not correct and ridiculous, right?

If to hide that 0-level swap line if swapping was turn off, then we have good illustration of swapping state/mode: disabled.

Showing always 0-level swap line is not informative and leads to confusion:
(is is enabled and not using at that time)
or
(is it disabled).

May be to check, for example, the
swapon --show
output to decide to hide that line or not?

Thank you all!

Still the same in v5.13.2.

If despite of all msgs you want to list that non-informative zero-level line than make is non-solid for example dashed at least.

Thanks!
