Var MyAxis : TChartAxis ;
begin
MyAxis := TChartAxis.Create( Chart1 );
Series2.CustomVertAxis := MyAxis;
//You can modify any property of the new created axes, such as the axis color or axis title
With MyAxis do
begin
Axis.Color:=clGreen ;
Title.Caption := 'Extra axis' ;
Title.Font.Style:=[fsBold];
Title.Angle := 90;
PositionPercent := 20; //percentage of Chart rectangle
