6.3 Using the COMPARE function to Compare Historical Graphs
Graphs can be superimposed for comparison using the Compare function. Refer to Figure 20,
which is used as a reference graph.
Place one graph over the other, and reduce the opaqueness down from 100 until one graph is
visible through the other.
