Since this is fake data that's not being updated, it has static dates. As time passes, the date-range calendar will continue to update but the data will not! So, if you want to see a good sample of data, we recommend you view 02/01/2014 - 03/01/2014.
Reading & Using This Graph
This graph is made custom based on the options you choose--Y axis, X axis, and date range. The bars in each category (weekday, time of day) are stacked like stairs: Instead of looking at the bars head-on, like a clustered bar chart, the bars have been turned sideways so you are seeing them from lowest to highest.
Note that if you choose a very small date range (say, less than one month), the bars will look a little funky!
