Histogram Chart Programming Considerations

Unlike other Cartesian charts, a histogram input is not specified by X and Y coordinates. Instead, a single array of raw data values is specified in the Y ChartDataArray of each ChartDataSeries. Depending upon the IntervalCreationMethod selected, histogram input may also use the X ChartDataArray of a ChartDataSeries to specify interval boundaries.

The following table lists the Data Arrays and describes the effect each one has on Histogram charts.

Property

Description

Holds the interval boundaries for histograms with XDataBoundaries as the IntervalCreationMethod.

Y

Holds the raw data values.

Y1

No effect for Histogram charts.

Y2

No effect for Histogram charts.

Y3
