Excel gives you two Y axes. Your data has never been that simple.

MultiYAxis is the charting engine Excel always lacked — independent Y axes on one chart, each with its own scale, units, and position. Built for engineers, scientists, and anyone whose data refuses to share an axis.

Built for Data That Refuses to Share an Axis

A few things that set MultiYAxis apart — see all features for the full picture.

📐

Multiple Independent Y Axes

Place any number of Y axes on either side of the chart — each with its own scale, units, and position. No shared scales, no compromises.

📏

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 it hits the chart. Convert units, shift baselines, normalize — without touching your source data.

🖼️

Export at Up to 4× Resolution

PNG, JPG, and SVG with presets for 16:9, letter, and A4. Pro removes the watermark. Insert directly into your worksheet too.

🎨

8 Color Palettes + Full Text Styling

Choose a palette or set colors individually. Control font, size, and color for title, axis labels, ticks, and legend — all in one panel.

💾

Templates & Undo / Redo

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