Method Summary

Modifier and Type	Method	Description
DecimationAlgorithm	getAlgorithm()	Returns the algorithm used by the plugin.
IsChart	getChart()	Returns the chart instance
protected ExtendedOptions	getConfiguration()	Returns the configuration element.
protected ConfigurationOptions	getOptions()	Returns the configuration options.
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.
void	setAlgorithm(DecimationAlgorithm algorithm)	Sets the algorithm used by the plugin.
void	setEnabled(boolean enabled)	Sets true if decimation are enabled.
void	setSamples(double samples)	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.
void	setThreshold(double threshold)	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.
