Do you mean to use a TChart on the panel?
If so
then you would do something like this
procedure PopulateGraph;
var Count : integer;
begin
With StringGrid do
begin
for Count := 0 to Rowcount-1 do
begin
Series1.AddXY(strtofloat(Cells[0,Count]),strtofloat(Cells[1,Count]), '' , clTeeColor );
end;
end;
end;
Hope it helps
