Plot values for a single field over time

@jsanz @tsullivan After working through all of the steps and still having some difficulty I've taken a step back to make sure that the data I'm working with is organized correctly first. This may be the underlying problem so I have a ticket open with support but also started a discussion thread called Convert message into eps data and create a visualization as well. Thanks for the help and I'll post here if I get this sorted out and the visualization setup.
