Enabled

Is decimation enabled? Default false 

.Enabled(true)

Algorithm

Decimation algorithm to use. Default 'min-max' 

.Algorithm(Algorithm.Lttb)

Samples

If the 'lttb' algorithm is used, this is the number of samples in the output dataset. Defaults to the canvas width to pick 1 sample per pixel. 

.Samples(2)

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. 

.Threshold(5)
