# Chart Making- Chart With 3 Data Series

Jun 30, 2008I have a chart with 3 data series. The series are located in columns A, B and C respectively. Series I is a general number anywhere from 0 to 100,000. Series 2 is also a number, but is is devided by series 1. So, if series 1 was 100,000 then series two would be 25,000/100,000 which is 0.25. Series three will always be numerator of series 2 or 25,000 in this example. The numerator, or the 25,000 will never change, so, in my example, series three will be a straight line across the chart because it is always 25,000.

In my example, the .25 is plotted on the left value axes, and series one is plotted on the right value acccess (secondary axis). Series three is just a line in the middle.

My problem is that sometimes the line, series 3, doesn't match the values in both the right and left values axes. So, if series one is 48,000, then series two would be 48,000/48,000 = 1, and series three would be 48000 - the straight line. The third series should be a line touching the 48,000 on the right and the number 1 on the left. It does touch the 48000 on the left, but is below the number 1 on the left.
