A sample distribution plot will let you see how your data is
distributed over a particular variable or function. Select the *
frequency* option in PLOT
and specify the number of intervals you want. You will get a
histogram of the number of samples in each interval of *y* vs the *y*
variable as shown in Figure 5. This option does not
work with multiple *y*'s, averaging, error bars, or cursor selection.

If the *y* range has been specified, then the interval is
*range*/*intervals* and the first interval starts at the minimum of the
range. Otherwise the minimum and maximum of the *y* data are used.
(The *y* graph range and linear/logarithmic parameters apply to the
*x* axis of the frequency plot; the *x* graph range and
linear/logarithmic parameters refer to the *y* axis of the frequency
plot.)

If you enter `M` after the graph is displayed, lines will be drawn
showing the mean and median values. If you enter `G`, you will
get a Gaussian fit and a line at one standard deviation in addition to
the mean and median lines.
