A histogram is a graphical representation that shows a visual impression of the distribution of data. The histogramProperties object controls the properties associated with the distribution of data.
histogramProperties: { binCount: cnumber binSize: bsize startBinValue: snumber},
where:
Is the number of group labels to draw, or undefined (automatic). The default value is undefined.
Is the size of the value range for assigning data values to a bin. Can be a number, an array of numbers (for variable bin sizes), or undefined (automatic). If binSize is an array, binCount is ignored and assumed to be the length of the binSize array. The default value is undefined.
Is a number to use as the first bin, or undefined (automatic). The default value is undefined.
Note:
The following request against the GGSALES data source creates a vertical histogram (ON GRAPH SET LOOKGRAPH VHISTOGR) with a bin count of 5:
GRAPH FILE GGSALES
