Since each graph is live, you can easily choose which data period you want
them to display. Use the time navigation at the top of the screen to have all
the graphs show trend data for the last year, quarter, month, or week.
You can also use the data fields to choose a custom period.
Each graph is also interactive, so you can click, and zoom right in the graph
to display a custom time period.
After zooming, you can click the "Reset zoom" button in the graph to zoom back out.
