public class SampledXYSeries
 implements FastXYSeries, OrderedXYSeries
                    
```
An implementation of FastXYSeries that samples its self into multiple levels to achieve faster rendering / zoom behavior. By default, uses 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 125 - 8x sampling

- Constructor Detail
  - SampledXYSeries
```
SampledXYSeries(XYSeries rawData, OrderedXYSeries.XOrder xOrder, float ratio, int threshold)
```
    Parameters:
    
    xOrder - If your data is in ascending or descending order, specifying it here speed up optimize render times.
    
    ratio - The ratio used to determine the size of each new sampled series.
    
    threshold - The desired size of the smallest sample series.
  - SampledXYSeries
```
SampledXYSeries(XYSeries rawData, float ratio, int threshold)
```
    Generate a SampledXYSeries from the input series.
    
    Parameters:
    
    rawData - The original series to be downsampled
    
    ratio - The ratio used to determine the size of each new sampled series.
    
    threshold - The desired size of the smallest sample series.

```
 void setAlgorithm(@NonNull() Sampler algorithm)
```
  - getBounds
```
@Nullable() RectRegion getBounds()
```
    Returns:
    
    The min/max bounds of the raw data. Never null after construction unless explicitly set to null via setBounds.
  - setBounds
```
 void setBounds(@Nullable() RectRegion bounds)
```
  - getXOrder
```
@NonNull() OrderedXYSeries.XOrder getXOrder()
```
    The order of XVals as they appear in this series.
  - getRatio

  - setRatio
```
 void setRatio(float ratio)
```
  - resample
```
 void resample()
```
  - setZoomFactor
```
 void setZoomFactor(double factor)
```
    Set zoom factor; 2.5 = 2.5x zoom, 10.0 = 10x zoom etc. This method will set the zoom level to the closest available factor to the specified factor; a specified factor of 4.5x may result in an actual factor of 4x.
  - getMaxZoomFactor
```
 double getMaxZoomFactor()
```
  - getTitle
```
@Nullable() String getTitle()
```
    Returns:
    
    The title of this Series.
  - size
```
 int size()
```
    Returns:
    
    Number of elements in this Series.
  - getX
```
@Nullable() Number getX(int index)
```
    Returns the x-value for an index within a series.
    
    Parameters:
    
    index - the index index (in the range 0 to size()-1).
    
    Returns:
    
    The x-value.
  - getY
```
@Nullable() Number getY(int index)
```
    Returns the y-value for an index within a series.
    
    Parameters:
    
    index - the index index (in the range 0 to size()-1).
    
    Returns:
    
    The y-value.

```
    TIP: You can use union during to keep a running tally of min/max values when iterating.
    
    Returns:
    
    A RectRegion representing the min/max values that currently exist this series.
