Interface: ValueCoordinates

Defined in: packages/core/src/plot/capabilities.ts:248

Converts between this pane's screen y and its value. The value-side counterpart to XCoordinates.

yScale isn't handed over as-is because Scale has setDomain and setRange on it — if an extension could push the value axis around, this wouldn't be a coordinate converter anymore.
