arrayHeight

arrayHeight: number = 0

Gets the height of the 2-dimensional array of Z-Values where array is ranked [width][height]

Readonly dataChanged

dataChanged: EventHandler<IDataChangeArgs> = new EventHandler<IDataChangeArgs>()

An EventHandler which is raised when the data changes.

remarks

To subscribe to dataChanged, use the following code:

const dataSeries = new XyDataSeries(wasmContext);
const callback = () => {
   // Data has changed
};
dataSeries.dataChanged.subscribe(callback);

To unsubscribe from dataChanged, use the following code:

const dataSeries = new XyDataSeries(wasmContext);
dataSeries.dataChanged.unsubscribe(callback);
