Clicking on plot area does not change launch window parameters

[Trotsky21]

Using Mozilla Firefox 31 and Windows 8.1. Using the Launch Window Planner normally, but clicking in the plot area per instructions "Click on any point on this plot to see full details of the selected transfer." does not change any of the details. In other words, the plot is fixed at the lowest delta value and the user cannot select other areas in the plot. I've used this planner before on a different computer (Mozilla, Windows 7) and recall that it worked fine.

I have confirmed the inability to select any other area in the plot is not related to the OS - I was able to access the Planner on another machine running Mozilla and Windows 7.0. The user is unable to change any of the launch window data by clicking on any other area of the generated plot.
