[supermuckl]

schonmal in das manual dafür geschaut?
da steht doch alles drin !

auszug schon auf der ersten seite:

Delphi-Quellcode:

Coding your datasource
You may populate your Chart at runtime by coding which Series to add to the Chart and defining the fields of those Series.
It assumes you have a table on your form, Table1 with fields Name and Amount.

Var 
MySeries,Ave:TLineSeries;

MySeries:=TLineSeries.Create( Self );
With MySeries do
begin
 ParentChart:=DBChart1;
 DataSource:=Table1;
 XLabelsSource:='Name';
 YValues.ValueSource:= 'Amount';
 CheckDatasource;
end;
