Adding a new line / row of data in a chart & second set of data on right
I have some simple line charts made and I need to add a third line from another row of data in the chart. How do I add another line of data to the chart? I cannot for the life of me find this option. It gave me two lines by default but I need more in the chart.
Question 2 is how do you add another set of data to the right hand side of a chart (for comparing numbers of a different scale?). For example, having raw numbers on the left for one line to compare to, and then % on the right for another set of data to compare to. Used to do this in Excel all the time.
Would appreciate any/all help, its somewhat of an urgent matter. Project due early in the morning =\
Thanks! (iWork '09)
