Every Feature, Fully Documented
MultiYAxis is built for complex data. Here's what's inside.
Axes & Scaling
Multiple Independent Y Axes
Place any number of Y axes left or right, each with its own scale, units, log mode, and position. Axes stack cleanly outside the plot area â no overlap, no clipping.
Axis Sync
Lock any two Y axes to share the same data range â useful when comparing series that should remain proportional. Sync is computed automatically from the visible data.
Normalized Mode
Rescale all series to 0â100% with one click. Compare relative trends across wildly different units â 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 â without modifying your source data.
Visualization & Overlays
5 Chart Types
Line, spline, area, bar, and scatter â mix and match per series. Each series gets its own type, color, and Y axis assignment independently.
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 â directly on the line itself.
Reference Lines & Regions
Add horizontal threshold lines, vertical event markers, and shaded X-range regions â each with a custom label, color, and dash style.
Statistics Panel
Min, max, mean, and standard deviation for every visible series â displayed automatically 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. The preview updates in real time as you adjust any setting.
Styling & Appearance
8 Color Palettes
Choose from Default, Warm, Cool, Pastel, Colorblind Safe, Earth, Vibrant, or Monochrome â or override any series color individually. Color changes propagate to axes and legend automatically.
Full Text Styling
Control font family, size, and color independently for chart title, axis labels, tick labels, and legend. Tick and label colors can match their axis color or be set to a single global override.
Chart Templates
Save your complete chart configuration â axes, series, colors, reference lines, and all styling â as a named template. Load it onto any new dataset in one click.
Export & Workflow
Export: PNG, JPG, SVG
Export at up to 4Ã resolution with aspect ratio presets â 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 â ready for reports, dashboards, and sharing without leaving Excel.
Undo / Redo
Full 20-level undo and redo with intelligent coalescing â typing a label counts as one undo step, not one per keystroke. Accessible via toolbar or keyboard shortcut.
