Calculates the median of all values from IndexLow to IndexHigh in the SourceChart and returns the median. The function also returns the timestamp of the median value if the SourceChart contains timestamps (SourceChart.Values.IsDateTime=True)

Namespace: FMX.RS.ChartFunction

Delphi

public
  class function Median(const SourceChart: TRSCustomChart;
  IndexLow, IndexHigh: Integer; var TimeStamp: TDateTime;
  SourceDim: Integer): TRSChartValueType; overload;

Parameters

SourceChart

Type: TRSCustomChart

Chart to calculate the median from

IndexLow

Type: Integer

Lower bounds index into the SourceChart

IndexHigh

Type: Integer

Upper bounds index into the SourceChart

TimeStamp

Type: TDateTime

TimeStamp of the new value

SourceDim

Type: Integer

Return Value

Type: TRSChartValueType

Note that this function is a class procedure so it may be called even if the TRSCustomChartFunction is not instantiated.

The function can also be called by custom functions. For example, you could create a custom function that calls this function and then does something with the result
