object Chart1: TChart
  Left = 404
  Top = 168
  Width = 400
  Height = 250
  BackWall.Brush.Color = clWhite
  BackWall.Brush.Style = bsClear
  Title.Text.Strings = (
    'TChart')
  TabOrder = 3
  object Series1: TFastLineSeries
    Marks.ArrowLength = 8
    Marks.Visible = False
    SeriesColor = clRed
    LinePen.Color = clRed
    XValues.DateTime = False
    XValues.Name = 'X'
    XValues.Multiplier = 1.000000000000000000
    XValues.Order = loAscending
    YValues.DateTime = False
    YValues.Name = 'Y'
    YValues.Multiplier = 1.000000000000000000
    YValues.Order = loNone
  end

Okay ... I think now I get it.
Try some of these components:

also you will probabely need the directX

Not to forget the source of many good components (see the audio section):

By the way... I really think that those visualizations should be made in assembly.
