A few highlights — see all features for the full picture.

Unlimited Independent Y Axes

Place any number of Y axes on either side of the chart — each with its own scale, units, and position.

Series Highlights

Mark a sub-range on any series with a thick colored band. Highlight a peak load, a failure window, or any region of interest directly on the line.

Reference Lines & Regions

Add horizontal threshold lines, vertical event markers, and shaded X-range regions — each with a custom label, color, and dash style.
