io.deephaven.clientsupport.plotdownsampling.RunChartDownsample

All Implemented Interfaces:

Function<Table,Table>

public class RunChartDownsample
extends Object
implements Function<Table,Table>

Downsamples a table assuming its contents will be rendered in a run chart, with the each subsequent row holding a later X value (i.e. is sorted on that column). Multiple Y columns can be specified, as can a range of values for the X value (providing a "zoom" feature, with high resolution data in that range, and low resolution data outside of it).
