The Budget By Project Class tab in the Scenario Comparison page provides a graph comparing the budget per period for each scenario by project class. See Figure 5-7. Scenario Comparison page, Budget By Project Class tab.
The graph for each scenario consists of a bar chart with adjacent bars (one for each project class) in each period. The bars allow you, for each scenario, to compare the budget distribution among the various project classes—Core (Keep the Lights On), Efficiency, Growth, and Innovation.
For information about the cost (budget) calculations, see Overview of the Scenario Comparison Page.
To change the time interval used for the horizontal axes in the graphs on all the tabs except the Efficient Frontier tab, select a new value in the Graph Period Interval field and click Change (see Figure 5-3. Graph Period Interval field).
