Imagine you have a chart with 2 series and 3 values each.
Here you introduce the values:
ChartFX1.OpenDataEx(COD_VALUES,2,3); {Make sure you include                                           cfxocx2 in your uses clause}

ChartFX1.ThisSerie:=0; {Now working with the 1st serie}
ChartFX1.Value[0]:=30;
ChartFX1.Value[0]:=20;
ChartFX1.Value[0]:=40;
ChartFX1.ThisSerie:=1; {Now working with the 2nd serie}
ChartFX1.Value[0]:=15;
ChartFX1.Value[0]:=45;
ChartFX1.Value[0]:=25;
ChartFX1.CloseData(COD_VALUES);

Now, if you want to get a value from the first point of the first serie do the following:

var  
    ReturnValue: Real;

ChartFX1.ThisSerie:=0; {Set the working serie the 1st one}
ReturnValue:=ChartFX1.Value[0];  {Here you have the value}
