    Gnuplot can also fit curves to a set of data points.
    You may specify the funcion and gnuplot fits the parameters.
    There's loads of information on unsing gnuplot on the web.

    You can try Octave (duplicates Matlab functionality)

    https://www.gnu.org/software/octave/download.html

    Octave/Matlab is a scientific programming language, and takes time to master.

    The idea would be to enter the data, use polyfit to fit a least-squares parabola through the data, (and polyval to generate the points on the curve). See the attached for what it might look like.
