Dear Jilberto,
    assuming that you are using Flair to generate the plot, since it
is based on gnuplot, you could calculate yourself an approximation
of the integral with a quick code. You can find an example with
the Simpson's rule in the gnuplot documentation:

These commands could be inserted in Flair in the Plot tab in
the lower part of the window. If you save the project, they will
also be saved into the .flair file.
