Interface: XDomainChangePayload ​

Defined in: packages/core/src/plot/events.ts:40

The visible x range changed.

The y domain isn't reported — that follows the series, it isn't something the user moved.

Properties ​

dataRange ​

dataRange: Range | null

Defined in: packages/core/src/plot/events.ts:52

The x range of the data held. The reference for measuring closeness to the end. null if there's no data.

endX ​

endX: number

Defined in: packages/core/src/plot/events.ts:47

startX ​

startX: number

Defined in: packages/core/src/plot/events.ts:46

The range currently visible, in data x. Not an index even in bar-index coordinates — it has to share units with dataRange so a subscriber can measure "how close to the end."
