Retrieving the serie values at crosshair
While the tracker window will display serie values at crosshair position, it can often be interesting to retrieve the values in code. Following code snippet shows the serie values in the caption of the form:
procedure TForm1.AdvChartView1MouseMove(Sender: TObject; Shift: TShiftState;
X, Y: Integer);
var
i: integer;
cp: TChartPoint;
s: string;
begin
with AdvChartView1.Panes[0] do
begin
s := '';
for i := 0 to Series.Count - 1 do
begin
cp := GetChartPointAtCrossHair(i);
if s = '' then
s := floattostr(cp.SingleValue)
else
s := s + ':' + floattostr(cp.SingleValue);
end;
end;
end;Pricing
