Interface IsDefaultDecimation

All Known Implementing Classes:

Decimation, DefaultChartDecimation, DefaultDecimation

public interface IsDefaultDecimation

Interface to define DefaultPluginId.DECIMATION plugin defaults.

Method Summary

Modifier and Type	Method and Description
DecimationAlgorithm	getAlgorithm() Returns the algorithm used by the plugin.
double	getSamples() If the DecimationAlgorithm.LTTB algorithm is used, this is the number of samples in the output data set. Defaults to the canvas width to pick 1 sample per pixel.
double	getThreshold() If the number of samples in the current axis range is above this value, the decimation will be triggered. Defaults to 4 times the canvas width. The number of point after decimation can be higher than the threshold value.
boolean	isEnabled() Returns true if decimation are enabled.
