In the Cartesian coordinate system, each point is characterized by a pair of coordinates (X, Y). In a common case, X’s are provided by the BootstrapChartCommonSeriesBase.ArgumentField; Y’s are provided by the BootstrapChartSeries.ValueField
.
Certain series types require more than one value field, because their points are characterized by a larger number of coordinates. These series types are:
Range-like series types
Range bar and range area require two value fields: BootstrapChartSeries.RangeValue1Field and BootstrapChartSeries.RangeValue2Field.
Financial series types
Stock and candlestick require four value fields: BootstrapChartSeries.OpenValueField, BootstrapChartSeries.CloseValueField, BootstrapChartSeries.HighValueField and BootstrapChartSeries.LowValueField.
