I have an x-y (scatter) graph with non-integer, all positive x values and a
scrollbar set with an upper and lower limit. As I scroll, a vertical cursor
is moved through the chart but only to integer values. I'd like the vertical
cursor bar to move to each of the actual non-integer x values in my data as
I move the scrollbar.

Try using the integer values to feed a formula like INDEX(), to choose
the nth X value in the data. If the X values are not in order, try using
RANK() instead.
