Instructions to use

Black highlight circle means it is a focus point.
The initial one is the start of the line, you can change this one with the drop down menu.
You can also click on the bar graph to highlight another point that correlates the starting point to the new highlighted station.
Red highlight on circles means bad data, ignore these when trying to find problem stations.
Size of circles means a binned time. Small = less than 30 second std. Medium = 30 to 60 second std. Large = 60+ second std.
Line drop down widget allows the user to observe different lines.
Starting Point drop down allows the user to change the starting point highlight, and bar graph start.
Direction radio allows the user to change direction of the line
Slider widget changes the hour of the day and allows the user to observe statistics at that binned hour of the day.
