Everything MultiYAxis Can Do

Built for complex, multi-parameter data. Here's what's inside.

Axes & Scaling

Unlimited Independent Y Axes

Place any number of Y axes on the left or right side of your chart. Each axis has its own scale, units, log mode, and color. Axes space themselves automatically — no overlap, no clipping.

Axis Sync

Lock any two Y axes to share the same data range. Useful when comparing series that should stay proportional. The shared range is computed automatically from the visible data.

Normalized Mode

Rescale all series to 0–100% with one click. Compare relative trends across different units — temperature, pressure, RPM, and voltage on the same visual scale.

Per-Series Transform

Apply a scale multiplier and offset to any series before plotting. Convert units, normalize baselines, or shift values — without modifying your source data.

Visualization & Overlays

5 Chart Types

Line, spline, area, bar, and scatter — mix and match per series. Each series gets its own type, color, and Y axis assignment.

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.

Annotations

Add text notes tied to any data point on any series. Control font size, color, and optional arrows. Add as many annotations as you need.

Statistics Panel

Min, max, mean, and standard deviation for every visible series — displayed below the chart preview with configurable number formatting.

Live Plot Preview

Full-screen chart preview with unified crosshair tooltip, zoom, reset, and pop-out mode. Updates in real time as you adjust any setting.

Styling & Appearance

8 Color Palettes

Default, Warm, Cool, Pastel, Colorblind Safe, Earth, Vibrant, or Monochrome — or override any series color individually. Colors propagate to axes and legend automatically.

Flexible Axis Label Placement

Show axis titles beside the axis, above the plot, or below the plot. Adjust the label angle from 0 to 90 degrees for the best fit.

Full Text Styling

Control font family, size, and color independently for chart title, axis labels, tick labels, and legend.

Chart Templates

Save your complete chart configuration — axes, series, colors, overlays, and all styling — as a named template. Load it onto any new dataset in one click.

Export & Workflow

Export: PNG, JPG, SVG

Export at up to 4x resolution with aspect ratio presets — 16:9, square, letter, or A4. SVG produces lossless vector output. Pro plans export without watermark.

Insert Into Excel

Embed your chart directly into the active worksheet as a native image — ready for reports, dashboards, and sharing without leaving Excel.

Undo / Redo

20-level undo and redo with intelligent coalescing — typing a label counts as one undo step, not one per keystroke.
