TellPlot 2.0 adds business-ready multi-series categorical comparisons while preserving the existing waterfall and scalar categorical workflows.
Highlights:
- Compare 2 to 4 ordered series in editable bar and column charts.
- Shared screen, SVG, and PNG behavior for series ordering, palette, legend, labels, group regions, annotations, and emphasis.
- A typed schema
3.0.0contract and the publicprojectCategoricalComparisonprojector. - Compatibility retained for schema
1.0.0waterfall and schema2.0.0waterfall/scalar categorical data. - Stage-only npm Trusted Publishing, human WebAuthn approval, and SLSA provenance tied to the immutable
v2.0.0tag.
Breaking contract:
- Public discriminated unions include the schema
3.0.0comparison variant. Exhaustive TypeScript consumers must add the new branch. - Schema generations remain explicit; TellPlot does not silently migrate source or view data.
Install with npm install tellplot@2.0.0.
