I have a simple bar chart of programming language popularity with

  With Chart1BarSeries1 do
  begin
       AddXY(0,3,'VB',clLime);
       AddXY(1,14,'Lazarus',clBlue);
       AddXY(2,3,'C',clGreen);
       AddXY(3,2,'Java',clYellow);
       AddXY(4,7,'Delphi',clPurple);
       AddXY(5,4,'BASIC',clRed);
  end;

This means VB has 3 votes, Lazarus has 14 votes etc.

How can I make the words 'VB','Lazarus'... etc appear along the x-axis
instead of 0, 1, 2, 3, 4, 5, 6 ?

I don't know if there is an easier way, but that's how it works for
me:

The x axis is labelled by strings from an external chart source.
Unfortunately you cannot use the internal source of the series also on
the x axis. But it you can use a separate ListChartSource instead.

- Add a TListChartSource to the form.
- Add your data to the ListChartSource by calling
    with ListChartSource1 do begin
      Add(0, 0, 'VB', clLime);
      Add(1, 14, 'Lazarus, clBlue);
      ...
    end;
- Set the BarSeries's Source to ListChartSource1 - now the data are
available for the series.
- To the show the texts as axis labels set the BottomAxis.Marks.Source
to ListChartSource1 as well, and set its Style to smsLabel.

Quoteyou cannot use the internal source of the series also on the x
axisTechnically, you can, but only at run-time.

Thanks wp - it works perfectly.

Just a small clarification -
set the Chart1.BottomAxis.Marks.Source to ListChartSource1 as well.

You mean this?
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   function
TChartSeries.AddY(AY: Double; ALabel: String = ''; AColor: TColor =
clTAColor): Integer;
