LOGS
Since the Feedstock Log and the Project Scenario Log each have a comparative data point
that allows the user to evaluate different strategies (ie. $/MMBtu and $/kWh respectively), basic
graphing functionality was included to compare all data entries. This can be found at the far
right column of each Log sheet. When pressed it creates a chart as shown in the example
below.
