Shirley -

You probably need to set up another worksheet range, to hold the manipulated data
needed in the chart. I am guessing from the description that if you divide all other
values by the low company's values, you will get your normalized values. Plot this
normalized range.

I have 3 points of data for 10 separate firms. I currently have data plotted
as a line graph, but want to index the graph the following way:

- Firm with lowest data point is index "1"
- All other lines for other firms are a factor of that line "1"
