Manual page for times(PL)

DESCRIPTION

Ploticus can plot time values directly. Time arithmetic may also be done using functions. This page describes the supported time formats (see KEY below for explanation of codes).

SUPPORTED FORMATS

  • hh:mm (example 11:25)
  • hh:mm:ss (example 11:25:02)
  • mm:ss (example 25:02)

DEFAULT FORMAT

The default format is hh:mm.

USING VARIOUS TIME NOTATIONS

To work with data having other time notations, use the format portion of the xscaletype or yscaletype attributes of proc areadef or proc defineunits.
For example:
 #proc areadef
  xscaletype: time mm:ss

DISPLAY FORMATS

In addition to the time arithmetic notations shown above, the following formats may be used to display time values:
  • hh:mma (example: 11:25am)
  • hhA (example: 11AM)
  • Others: hh:mm:ssa m:ss hh mm m ss s

BASIC UNIT

The basic time unit is a minute, regardless of which notation is in use. Axis stubs and tics may be expressed in hours or seconds if desired.

KEY TO CODE ABBREVIATIONS

hh = hour, 00 to 23 (00 to 11 for am/pm notation)
h = hour, 0 to 23, (0 to 11 for am/pm notation)
mm = minute 00 to 59
m = minute 0 to 59
ss = second 00 to 59
s = second 0 to 59
ai = am/pm notation (use A capitals e.g. AM or PM)

NOTES

There are a number of functions for manipulating times that may be used in ploticus scripts.
