Preview: All TeeChart "functions" (56 statistical, financial and mathematical algorithms), can now be used with TDataItem data (no chart series are necessary !) Code is very small:

var MyFunction : TDataFunction; MyFunction:=TDataFunction.CreateFunction(TExpMovingAverage);
MyFunction.Source := BIGrid1.Data; // <-- can be any TDataItem

BIGrid2.Data:=TDataItem.Create(MyFunction);

TeeChart Functions have their own specialized parameters, for this example using an Exponential Moving Average:

MyFunction.Period := 10; // average last 10th data values
