In my project I've got several TCharts with 2 series and 2 bars in each series. []1

On each of them I need to show the value of the series bars on mouse hoovering over them. I'm using onm ouseMove event:

    procedure TfrmBoard.chartCountMouseMove(Sender: TObject; Shift:
        TShiftState; X, Y: Integer);
    var
      SeriesIndex  : Integer;
    begin
      with Tcontrol(Sender) do
      begin
        seriesIndex := (Sender as TChart).series[0].clicked(X,Y);
        ShowHint := SeriesIndex <> -1;
    
        if ShowHint  then
           Hint := FloatToStr((Sender as TChart).series[0].YValues.Value[seriesIndex]);
    
      end;

end;

This code shows the values of the first series in the chart, but not of the second.

If I add a loop, the event will show values of the second series only.

procedure TfrmBoard.chartCountMouseMove(Sender: TObject; Shift:
    TShiftState; X, Y: Integer);
var
  SeriesIndex  : Integer;
  i: Integer;
begin
  with Tcontrol(Sender) do
  begin
    for I := 0 to (Sender as TChart).SeriesCount - 1 do
    begin

    seriesIndex := (Sender as TChart).series[i].clicked(X,Y);
    ShowHint := SeriesIndex <> -1;

    if ShowHint  then
       Hint := FloatToStr((Sender as TChart).series[i].YValues.Value[seriesIndex]);
    end;

  end;

end; 

Can somebody help how to show values for both series?

CodePudding user response：

You have to break loop when ShowHint becomes True, otherwise it might be overwritten with next False values

if ShowHint  then begin
   Hint := FloatToStr((Sender as TChart).series[i].YValues.Value[seriesIndex]);
   Break;
end;

By the way, does your TChart have event OnMouseEnter for SeriesXX objects?
