plotsample
Display a sample plot.

Description
plotsample displays some noisy sample data. Try to fit the data with 
showfit, 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).
