This method was renamed to RecalcStats long time ago, but it was made "protected" instead of public.
This method was replaced with a public boolean variable that indicates if the value list min,max,etc values should be recalculated
again or not:
Series1.YValues.Modified := True;
You can still call the method via a small hacking, but this should not be necessary, setting Modified to True should be enough:
This is one of the very few (maybe only 3 o 4) items that have been changed or deprecated since version 1, back in 1995 ! <grin>
