* An implementation of {@link FastXYSeries} that samples its self into multiple levels to
* achieve faster rendering / zoom behavior. By default, uses {@link LTTBSampler} as
* it's sampling algorithm. Note that this algorithm does not yet support null values.
*
* Sampling behavior is controlled by two values:
* Ratio: A value greater than 1; controls the sampling ratio of each successive series. For example,
* a step of 2 would mean that each successive series contains 2x fewer points than the previous.
*
* Threshold: A value < the original series size; controls the lower limit at which point sampling should stop.
* For example, sampling a series with size 1000 given a ratio of 2 and a threshold of 100,
* three sampled resolutions will be generated:
*
* 500 - 2x sampling
* 250 - 4x sampling
