SUMMARY
In Microsoft Excel, to display two y-axes on a 2-D chart, you use an Overlay on the chart. When you create an overlay, at least one series must be used in the overlay. To create an additional y-axis that is identical to the first y-axis without displaying an overlay series, include an empty series in your chart and format this empty series as as the overlay series.

MORE INFORMATION
To create a 2-D chart with two identical y-axes, do the following:


 * 1) Create your chart using any of the conventional methods.
 * 2) With the chart active, click Edit Series on the Format menu.
 * 3) With New Series selected, create an empty series by placing a reference to an empty cell in the X Labels and Y Values boxes. Click OK to define the new series.
 * 4) On the Chart menu, click Add Overlay.
 * 5) On the Format menu, click Overlay. Make sure that the first overlay series is the last series available (the empty one).
 * 6) On the Chart menu, click Axes. In the Overlay box, check (enable) the Value (Y) Axis check box. Click OK to accept the change.
 * 7) Select the new axis on the right side of the chart, and click Scale on the Format menu.
 * 8) Change the scale of the new axis to match the primary y-axis.
 * 9) Change the color of each series back to its original color.

NOTE: If your chart has a legend, when you create any new series, even an empty one, the legend will be changed.
