SUMMARY

When opening the memory use history initially, it for some reason overlapped the labels of swap and memory use?

Also the line starts out very weirdly. The memory usage profile was flat for the last 10 hours, but the widgets shows a few weird jumps in the beginning. This is probably related to the smoothing?

All of that fixes itself after waiting for a bit and/or switching tabs.

STEPS TO REPRODUCE
1. Open system monitor
2. Go to history tab

OBSERVED RESULT

See intro

EXPECTED RESULT

Labels don't overlap and curve goes smoothly or sharply from 0 to 53 instead of wiggling at the start and end.

This is an unfortunate artifact of the smoothing algorithm that doesn't deal well with rapid changes in value. Unfortunately it's all a tradeoff since there are ways to avoid the spikes but those cause other issues. Right now the algorithm at least matches what other chart libraries out there do.
