Changing point sizes

[glazer]

I have a chart on which I have plotted say 20 points using a pointseries. Each point is plotted as a circle of a certain size. How can I arrange it that every odd point is largere than the even points? When I change the size of one point in the series is automatically affects all the points.

Hi Mike,

You could use OnGetPointerStyle event to change every pointer size. You could do something like following;

Code: Select all

var OddSize, EvenSize: Integer;

//...

function TForm1.Series1GetPointerStyle(Sender: TChartSeries;
  ValueIndex: Integer): TSeriesPointerStyle;
begin
  if ValueIndex mod 2 = 0 then
  begin
    Series1.Pointer.HorizSize := OddSize;
    Series1.Pointer.VertSize := OddSize;
  end
  else
  begin
    Series1.Pointer.HorizSize := EvenSize;
    Series1.Pointer.VertSize := EvenSize;
  end;

  Result := psCircle;
end;

Many thanks. I will give it a try
