You need to get a reference to the Data::Set object:

  const Data::Set &s = fan->get_plot()->get_plot_data(curve_index).get_set();

See http://www.gnu.org/software/goptical/manual/Data_Set_class_reference.html

You can then use the interpolate functions on this object. If you want to 
access the data, you need to cast to Data::DiscreteSet.

Best,
