How to print certain points?

[User (Legacy)]

Hi! 

I need to print charts by pages (the number of pages is specified by users 

via custom dialog box). 

And if the total number of points doesn't divide by the specified number of 

pages evently (e.g. 10 points by 3 pages), the last page should have less 

points than other pages (e.g. 4+4+2). 

I use SetScrollView and Paint methods to print, i.e. 

SetScrollView(1,4) 

Paint(...) 

SetScrollView(5,8) 

Paint(...) 

SetScrollView(9,10) 

Paint(...) 

However the last page printed contains 4 points, 7 thru 10 (so two pages 

"overlap"). 

How can I print only points 9 and 10? 

Thanks
