Description: Draw Histogram Plot Command: Plots a frequency histogram of the specified column in the
current statistics matrix (reserved variable DAT).
The data column to be plotted is specified by XCOL and is stored as the first parameter in the
reserved variable PAR. If no data column is specified, column 1 is selected by default. The y-
axis is autoscaled and the plot type is set to HISTOGRAM.
HISTPLOT plots relative frequencies, using 13 bins as the default number of partitions. The RES
command lets you specify a different number of bins by specifying the bin width. To plot a
frequency histogram with numerical frequencies, store the frequencies in DAT and execute
BINS and then BARPLOT.
When HISTPLOT is executed from a program, the graphics display, which shows the resultant
plot, does not persist unless PICTURE, PVIEW (with an empty list argument), or FREEZE is
subsequently executed.

Command
Description: Hours-Minutes-Seconds Minus Command: Returns the difference of two real numbers, where
the arguments and the result are interpreted in hours-minutes-seconds format.
The format for HMS (a time or an angle) is H.MMSSs, where:
• H is zero or more digits representing the integer part of the number (hours or degrees).
• MM are two digits representing the number of minutes.
• SS are two digits representing the number of seconds.
• s is zero or more digits (as many as allowed by the current display mode) representing the
decimal fractional part of seconds.
