plotsample
Display a sample plot.
Description `

    plotsample displays some noisy sample data. Try to fit the data with
    showfit or selectfit, following the instructions given in the command
    window. The sample data is chosen randomly among the 9 predefined plots
    described below.

    plotsample is also available from the item 'Plot Sample' of the EzyFit
    menu (see efmenu).

    plotsample(OPT)  specifies the sample plot:
      'power':   noisy power law
      'linear':  noisy data to be fitted by a linear function
      'damposc': damped oscillation
      'cste':    noisy constant
      'exp':     noisy exponential decay
      'hist':    histogram of 1000 realizations of a random variable
      'hist2':   histogram with two gaussian peaks.
      'powco':   noisy power law with an exponential cut-off.
      'poly2':   3 curves to be fitted by a 2nd order polynomial fit

    plotsample(N) specifies the number of the sample plot (1 to 8).

    plotsample(...,'fit') also displays the fit.

    [X,Y] = plotsample(...) also returns the sample data (this is
    equivalent to plotsample; [X,Y] = pickdata;).

    Example:
        plotsample power fit
        (it shows a power law and fits it).
