Inputs

NameTypeDefaultDescription

aggregate

any

'max'

The aggregate function for the date series. The function is used when a category (year, month, or other) contains two or more points. The Chart displays the return value of the function instead of the individual points. The aggregate option is supported for categorical chart axis only.

  • "count"—The number of values for the date period.
  • "max"—The highest value for the date period.
  • "min"—The lowest value for the date period.
  • "sum"—The sum of all values for the date period. Defaults to 0 if no data points are defined.
  • "sumOrNull"—The sum of all values for the date period. Defaults to null if no data points are defined.
  • "first"—The first value.
  • function (values, series, dataItems, category)—A user-defined aggregate function. Returns a single value or a data item.
  • object (compound aggregate)—Applicable to the Candlestick, Box Plot, and OHLC series. Specifies the aggregate for each data item field.
