Spiral Strip Web Studio

Spiral Strip Web Studio is a free online tool for visualizing numerical data as a spiral strip, including time series and other data. Segment colors, widths, and lengths can represent data values, with customizable labels and SVG or PNG image export.

Data values

One number per segment, in order. Separate with commas or whitespace, or use a JSON array.

Show color bar optional

Below the graphic, with only the minimum and maximum values labeled.

Segment labels optional

Segment outlines optional

Drawing quality & saving

Bézier segment boundaries

On by default. Uncheck to use adaptively subdivided straight edges. Segment lengths and gaps always use the accurate arc-length solver.

Boundary tolerance

Controls smoothness in both boundary modes, in the same units as segment widths. Smaller values add more curves or points automatically.

Smooth edges Transparent image background PNG resolution (DPI)

SVG stays sharp at any size. PNG resolution is relative to the 100 DPI drawing scale.

Export SVG text as curves

On by default. Uncheck to save editable text without an embedded font; its appearance then depends on available fonts.

No previous changes.

Save all settings and data in a project file to continue later. Importing can be undone.

Download a Python script with your current data and settings. Run it with the Spiral-strip Python library to recreate the graphic. The library also supports multiple spiral graphics in one Matplotlib figure, using subplots or subfigures.
