What You Can Do with MultiYAxis

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.

Reference Lines & Shaded Regions

Mark thresholds, event timestamps, and operating windows directly on the chart — labeled, colored, and styled your way.

Per-Series Transforms

Scale and offset any series before plotting. Convert units, shift baselines, or normalize — without touching your source data.

High-Resolution Export

PNG, JPG, and SVG at up to 4x resolution with aspect-ratio presets. Insert charts directly into your worksheet.

Color Palettes & Text Styling

8 palettes plus per-series color overrides. Control font, size, and color for title, axes, ticks, and legend.

Templates & Undo / Redo

Save your full chart configuration as a named template and reload it on any dataset. 20-level undo keeps you from losing work.
