how do I create a line graph from a common origin?

[Ray]

How do I have create a line graph with 3 lines having a common point of
reference or origin? I see financial charts showing investments, for
example, having $10,000 as a point of origin in order to show change in
investment value over time. I want to do something like that with other type
of data.

Normalize your data so all three series pass through the first point. If
series A starts at 9000, for example, and you want it to pass through 10000,
multiply each Y value by 10000/9000.
