statBin

The statBin function creates a new plotting context with new dataset which contains the "bin" statistic calculated on sample of a single numeric variable x. Firstly, it divides the range of values into bins (sequential, non-overlapping sections), and then it counts the number of observations in each bin. It's weighted, it means the weighted count for each bin is calculated (each element within a bin counted along with its weight). A bin-constructing methods can be configured.

Arguments

x

^Required

^Iterable ^Column ^String

The x argument is used to provide the sample (or its x-part) on which the statistic is computed.

weights

^Optional

^Iterable ^Column ^String

The weights argument is used to provide the weights of sample elements.

binsOption

^Optional

^BinsOption

The binsOption argument is used to determine whether bins are created by their total number or by their width.

BinsOption.byNumber(n: Int): values are divided into n bins (bins width is derived).
BinsOption.byWidth(width: Double): values are divided into bins of the width (the number of bins is derived).

binsAlign

^Optional

^BinsAlign

The binsAlign argument is used to specify bins aligning.

BinsAlign.center(pos: Double): bins are aligned by centering bin in pos.
BinsAlign.boundary(pos: Double): bins are aligned by boundary between two bins in pos.
BinsAlign.none(): no aligning.

Statistic properties

In this context, there are the following statistical properties that can be used to create mappings, customize tooltips, etc.

Stat.x

^{Column<Double>}

The Stat.x contains centers of bins.

Stat.count

^Column<Int>

The Stat.count contains numbers of observations in this bin.

Stat.countWeighted

^{Column<Double>}

The Stat.countWeighted contains weighted count (sum of observations weights in this bin). Without weights its values matches Stat.count values.

Stat.density

^{Column<Double>}

The Stat.count contains empirically estimated density in bins.

Stat.densityWeighted

^{Column<Double>}

The Stat.countWeighted contains weighted density. Without weights its values matches Stat.density values.
