OS: FreeBSD (i386) release 8.0-RELEASE
There are no graphics in "CPU History" and "Network History".
Just "Memory and Swap History" works.

If you know about coding at all, maybe you could take a look at the code and try to fix it yourself? I don't have freebsd myself.
I'm running KDE 4.4.2 on Kubuntu 9.10, and I encountered this bug as well. I've also seen it at least on 4.4.1, and maybe 4.4.0. There's a bug report on launchpad for this issue as well: https://bugs.launchpad.net/ubuntu/+source/kdebase-workspace/+bug/494463.
As I commented on launchpad, for some reason the lines for loading the sensors seems to have somehow been removed from the "SystemLoad2.sgrd" file. The easiest fix for this (though it obviously doesn't address the source of the bug) is to restore the configuration file from the default settings. For *buntu, the simplest way to do this is: "cp /usr/share/kde4/apps/ksysguard/SystemLoad2.sgrd ~/.kde/share/apps/ksysguard/"
Though obviously the location might vary slightly depending on the distribution.
I also had this problem, with KDE 4.8.4 on Debian unstable. The fix proposed by maniacmusician worked for me, though I don't know how my configuration became invalid in the first place. Unfortunately, I performed the fix without backing up my previous, invalid configuration file, so I can't provide it for comparison. Perhaps, if someone else still needs to apply this fix, they can first backup the configuration file and attach it to this bug report
I found 2 other bugs that had this same problem. I added a link to this bug in the comment, but they should probably be resolved as duplicates and this one can be confirmed. I did not see how I could do that (or IF I could do that).
Forgot to mention the 2 duplicate bug reports I found:
*** Bug 271793 has been marked as a duplicate of this bug. ***

"After some research I found that this was caused by missing lines in the file 'SystemLoad2.sgrd' (/home/xxxx/.kde/share/apps/ksysguard/SystemLoad2.sgrd)
The lines missing are the <beam> ones. Also seems that end tag </display> is lacking for cpu and network monitoring."
Confirm by duplicates

removing the systemload2 file seems to fix the issue.
Linux Mint here. The Network History is blank for eth0 but works for the wlan0 (wifi). This is the same behavior with Gkrellm tool. It seems that something changed inside the kernel (/proc, etc...), i am using the 3.13.0-24-generic
Also in kde 5.9.4 in arch. Cpu and network usage not showing in ksysgaurd only. working fine elsewhere as in widgets

Screenshot of absent network and cpu usage. Also memory displayed is wrong (1.2GiB instead of 8 GiB)
Resolved on replacing with default Systemload2.sgrd
Can someone do a diff between a working .sgrd and a non-working .sgrd file?
I was able to fix my broken System Load and Network graphs by copying the default “SystemLoad2.sgrd” file from /usr/share/ksysguard/ to ~/.local/share/ksysguard/.
My old SystemLoad2 looked like this: https://pastebin.com/9qw5dqff
Whereas my new SystemLoad2 looks like this: https://pastebin.com/EXc0pifa
Merci, this only confirms what was already found in bug 266520. Still needs someone to understand why the file gets saved corrupted (without <beam> and ending </display> tags.

Thanks very much for this workaround, I never would have figured it out. On openSUSE this worked:
cp /usr/share/ksysguard/SystemLoad2.sgrd ~/.local/share/ksysguard/
The posted solution in comment #33 did not work for me on KDE 5.16.3 with QT 5.13. The only fix I was able to find was to use the 'Import tab from file' dialog in ksysguard and to navigate to the system file /usr/share/ksysguard/SystemLoad2.sgrd and import this file.
This successfully added the original tab back to my ksysguard after the System Load disappeared from ksysguard altogether after attempting previous fixes, including deleting the corrupt file in ~/.local/share/ksysguard/ and replacing it with the /usr/share/ksysguard/SystemLoad2.sgrd.
On reddit (https://old.reddit.com/r/kde/comments/cejw1w/til_you_can_also_install_addons_for_applications/eu3rh99/) a cause for this bug was mentioned as a possibly a system crash and/or running out of available disk space. Accidentally running out of disk space on the /home (partition) also seems to coincide with this happening on my system.
I have the same issue on KDE Neon 5.19.5.
I also suffered from this bug. Until I applied the solution offered here to restore the (on manjaro) :
/usr/share/ksysguard/SystemLoad2.sgrd -> /home/user/.local/share/ksysguard/
SystemLoad2.sgrd had become very different from the original. Beams like
were completely missing from CPU and Network displays. Along with many many other differences.
I have no idea what could have provoked this change except maybe a crash in which I had to reinstall the grub.
