Origin Ver. and Service Release (Select Help-->About Origin): 8.6 SR3 Operating System: Win7
A suggestion for version 9.0: Can the scroll bars on graphs be made with a 'magnifier'? When dealing with long data sets (2M+ points), the scroll bar handle becomes just a thin line, and it is very hard to control. If there were a way to zoom in on the scroll bar handle, that would be very helpful.
Have you tried the new scroll capability in 8.6: http://originlab.com/index.aspx?go=Products&pid=1817 which simply allows you to use mouse scroll wheel and keyboard keys to scroll and pan? Would that work well with your data?
