I am looking for a way to plot or graph variables so I can visually see how the robot is interpreting data such as range finders.

Are you using just gazebo, or ROS based gazebo?

If so, broadcast the data to a topic, listin to it using something like matlab and plot it.

Maybe you can try rxplot or rviz on ROS.

In the short term, rxplot is the best approach.

Alternatively, you can write a plugin that outputs data for use with gnuplot.

Gazebo will eventually get a plotting utility, but that will not happen for a few more months.
