Zoom should manipulate "Page" and "MaxPoints

Hello,

If I make a "zoom" with the mouse in the chart
OR
"move" the chart to left or right with the mouse

I would expect that the
variables
Chart1.MaxPointsPerPage
Chart1.NumPages
Chart1.Pages.Current
would be automatic modified.

How can I solve this problem?
