Get a BarSeries by Index

[AchatSolutions]

Hello supportteam,

I am using Delphi 6 and TeeChart Pro v5.02.

I have a teechart with a dynamic amount of series.


Big version

So i add Series1 for 'Line19', 'Line20' and for 'Line21'. So i have three bars displayed but only one series.
When i add this series i would like to add the index of this three bars to a list.

But how can i do this? How do i know the index e.g. for Series1 'Line21'?

Background information:
When i add the series i would like to add the series index to a list with more information about this bar.

Then i would like to add a individual mark text for each displayed bar in the 'OnMarkTextEvent'.

Do you know a better way how to tagging a bar to add a individual mark text?

OnMarkTextEvent has an index param (ValueText), so you should be able to to the value--or am I missing something?

Thanks for the answer.

Yep thats right.. but i need the index param when i am adding a value to the bar --> outside the OnMarkTextEvent.

I need this because i would like to save more information about this bar in a list when adding a y value to the bar. Then in the OnMarkTextEvent i would like to search the list items which one has the same index param and then add a mark text that is in the list item to show an individual text for every bar.



Hope thats clear. Thanks!

Hi AChatSoluions,

You can obtain each series and point indexes like this:

Code: Select all

Uses Series;

procedure TForm1.FormCreate(Sender: TObject);
var SeriesIndex, ValueIndex: Integer;
    tmpSeries: TChartSeries;
begin
  tmpSeries:=Chart1.AddSeries(TBarSeries.Create(self));
  SeriesIndex:=Chart1.SeriesList.IndexOf(tmpSeries);

  ValueIndex:=Chart1.Series[SeriesIndex].Add(random);

  Chart1.Title.Text.Clear;
  Chart1.Title.Text.Add(IntToStr(SeriesIndex));
  Chart1.Title.Text.Add(IntToStr(ValueIndex));
end;

Hope this helps!
