There is TLineSeries.SetText (...), but there is no
TLineSeries.GetText.
How am I to read the text of the points? There is not a
TLineSeries.Text property neither.

If your series gets its data from the built-in or from an external
ListChartSource, you can access the text assigned to the datapoint by
means of the TChartDataItems stored in the ListSource of the series,
for example like

Code: [Select]var s: String;
...
  s := Chart1LineSeries1.ListSource.Item[datapointindex]^.Text;
