onData property

LifecycleSeriesListCallback<D>? onData

Called when data is drawn to the chart (not a redraw).

This step is good for processing the data (running averages, percentage of first, etc). It can also be used to add Series of data (trend line) or remove a line as mentioned above, removing Series.

Implementation

final LifecycleSeriesListCallback<D>? onData;
