[6.12.9] CPU Graph anomoly on dashboard

This is a very low priority issue, but one I've noticed in the last week or so (probably since upgrading to 6.12.9, but I don't recall when I first saw it).

The CPU graph on the Dashboard of the GUI always "drips" to zero at the left edge of the graph as the line runs off the edge of the graph. I've captured this GIF to show it:

You can see how it "drips" down the left hand edge of the graph.

Again, this is a very minor, low-priority issue, but one that is, hopefully, a quick fix.

Per the rules, here's the diagnostics file: nas-diagnostics-20240425-1658.zip
