18. How to I use a ScrollBar object to control horizontal scrolling of the data in
my chart?
You can place the ChartView object and the scroll bar in a parent container and use a
layout manager to position everything. If you place the scroll bar in the ChartView
you can still position it using a layout manager. The ChartView will always use the
entire content area of the underlying Control for its canvas and the scroll bars will sit
on top of this, not side by side. The example program LinePlotScrollBar uses two
scroll bars, a horizontal scroll bar to control scrolling of the x-axis, and a vertical
scroll bar that controls the magnitude of the y-axis. You need to add
hScrollBar1_Scroll and vScrollBar1_Scroll event listeners to the ChartView class to
process changes in scroll bar values.
As of this writing there seems to be serious problems with the .Net scrollbars, largely
due to the circumstance that they do not support trapping MouseDown and MouseUp
