I want to display multiple data lines in a chart. Each data line's X range
would be the same, the Y range may be different. Can I create multiple
"tracks" in an excel chart to display the data lines with each "track" having
it's own range and display option definitions? The tracks would be stacked
on top of each other (not overlayed on each other).

This is similar to stacking excel chart windows on top of each other and
each chart includes one or more data lines with the same XY range and display
definition.

Also, my data range will be long (hundreds of ft and I want to display each
inch) and I'd like to create a scrollable chart window. Is this possible?
The dynamic chart option identified at www.tushar-mehta.com allows you to
view a subset of the chart and may work, but moving the view window will be
more difficult than having a scrollbar.

thanks.
