HistogramChartSpec class
A histogram chart.
A histogram chart groups data items into bins, displaying each bin as a column of stacked items. Histograms are used to display the distribution of a dataset. Each column of items represents a range into which those items fall. The number of bins can be chosen automatically or specified explicitly.

HistogramChartSpec({double? bucketSize, String? legendPosition, double? outlierPercentile, List<
HistogramSeries> ? series, bool? showItemDividers}) - HistogramChartSpec.fromJson(Map json_)
Properties
- bucketSize ↔ double?
-
By default the bucket size (the range of values stacked in a single
column) is chosen automatically, but it may be overridden here.

-
series
↔ List<
HistogramSeries> ? -
The series for a histogram may be either a single series of values to be
