I have a problem:
I have realized a graphic interface with Borland Builder C++4 that permits 
to graph file.txt .  I utilize, for the graphs one TChart and one Series.
I have to draw vertical lines on a graph to select intervals . I know  the number of vertical lines 
after the run, reading a results file. The number of vertical lines change every run.
How can I create the vertical lines?
I wish I could select an interval of graph and realize a zoom of interval same.
How can I do it?

Thank you for your help.
