Haven't been able to locate the property or method that will allow me to know how many series are currently active.

thanks

Hi bcmiller,

I'm afraid there's no property for that. There's TChart.Series[SeriesIndex].VisibleCount but this method counts the number of visible points for a series. To achieve what you request yo ucan do something like:

Code: Select all

var
  i, Active: Integer;
begin
  Active:=0;

  for i:=0 to Chart1.SeriesCount-1 do
    if Chart1[i].Visible then inc(Active);
