Detailed Description

Bar graph of recent network round-trip samples.

Draws one bar per sample, oldest on the left. Bar height is relative to the window's own scale so the shape of the variance stays readable, while bar color maps each sample onto an absolute quality ramp (green at rest through red at ColorScaleMs) so a steady good ping never looks alarming. Size agnostic: the status bar embeds a small instance while the latency detail popup shows a large one.
