# Tutorial 11.  Demonstration of why it's good to work with .index and
#               .value instead of hardcoding to X and Y.
#
# We are going to change the orientation of the right_plot,
# but all of our dataspace linking will still work.  We'll also
# add another LineInspector to each plot to form a full crosshair.
