Creating a graph:
To create a graph of electricity use for the entire campus, choose the start and end dates, and the type of electricity use. "Total" is total metered campus electricity use. "Main" is the electricity that we purchase through the main campus meter. "Chiller" is the electricity used by the chiller plant that cools many buildings on the north side of campus. "Co-generated" is the electricity generated at Williams' heating plant. Click the "Create Graph" button.

Comparing graphs:
The graphs are draggable, so to compare two graphs after you have created them, you can either drag them to be side by side or drag one on top of the other.

Closing a graph:
Click on the red "x" close button on the upper right hand corner of the graph to close it.

Download data:
Choose a start date, end date, data type and click the "download data" button. Your browser should prompt you to either open the file or save it to disk. It is a .csv file which can be opened either with Microsoft Excel or a text editor.
