Marktip tool doesn't show z value for colorgrid series

[Fang]

hi,
what's the best way to ask marktip show (x z y) values for TColorGridSeries, I mean, what's the easiest way to just add z value to the ongettext function? thanks.

and one more question,

it looks like the delay time msec for TMarkTipTool only works for click event instead of move event , is that what supposed to be?

it'll be greate if there's one for move.

Hi Fang,

You can get the series point index using chart's OnMouseMove event and series' clicked method as done here:

Code: Select all

var
  Form1: TForm1;
  Index: Integer;

implementation

{$R *.dfm}

procedure TForm1.ChartTool1GetText(Sender: TMarksTipTool;
  var Text: String);
begin
  Text:=FloatToStr(Series1.XValue[Index])+', '+
        FloatToStr(Series1.YValue[Index])+', '+
        FloatToStr(Series1.ZValue[Index]);
end;

procedure TForm1.Chart1MouseMove(Sender: TObject; Shift: TShiftState; X,
  Y: Integer);
begin
  Index:=Series1.Clicked(X,Y);
end;

it looks like the delay time msec for TMarkTipTool only works for click event instead of move event , is that what supposed to be?

It works fine here using our current sources so you may expect it to work for the next maintenance release.
