For students at Caltech, or others who use a Caltech Card to pay for things, this page will generate plots of your spending, including individual transaction details and regression lines.
Unfortunately for you, it appears that you are using a browser without support for the <canvas /> tag,
which is what I use to create dynamically-generated plots based on your Caltech Card data. You can fix this by upgrading to a better browser, such as the latest versions of
Mozilla Firefox, Google Chrome, Safari, or
Opera. (And as you might expect, Internet Explorer is right out.)
Log on using your credentials from the Blackboard site. By default, this is your UID in both fields.
(Note: these credentials will be transmitted over the internet without encryption. If someone is out to get you, you might not want to use this site—especially if you use the same password elsewhere.)
