TIC MARK LABEL FORMAT

Name:
    ...TIC MARK LABEL FORMAT
Type:
    Plot Control Command
Purpose:
    Specifies the format of the labels associated with the major tic marks on subsequent plots.
Description:
    This command has three uses.

    1. For linear scales the following formats are available:

      ALPHA - the tic labels will be user-supplied (via the TIC MARK LABEL CONTENT command) alphanumeric strings.
      REAL - linear scales are drawn with numeric values.
      EXPO - linear scales are drawn in exponential format. The default is E15.7 format. Use the TIC MARK LABEL DECIMAL command to control the number of digits (e.g., TIC MARK LABEL DECIMAL 4 will use an E12.4 format. This option was implemented 1997/07.

    2. Log scales can be drawn in one of 3 formats. The available formats are:

      POWER - the corresponding power of 10 (e.g., 1 for 10**1) is drawn for the tic label.
      REAL - the corresponding real number (e.g., 10 for 10**1) is drawn for the tic label.
      EXPO - the tic label is drawn in exponential format (e.g., 10**1). The tic label must be drawn with a software font in order for this option to work correctly.

    3. You can specify a variable be used to determine the contents of the tic mark labels:

      GROUP LABEL - use a group label variable for the tic mark labels (the variable name is specified on the TIC MARK LABEL CONTENT command).
      ROW LABEL - use the row labels for the tic mark labels (no TIC MARK LABEL CONTENT is needed).
      VARIABLE - use the contents of a numeric variable for the tic mark labels (the variable name is specified on the TIC MARK LABEL CONTENT command).

      The 2019/12 version updated this option to support character variables as well as numeric variables. See Program 5 below for an example.

      Group labels are useful for box plots and other plots that are plotted against a group-id variable. The VARIABLE option can be used to generate a "reverse" axis. The ROW LABEL option is most commonly used for bar charts (and related type plots).

Syntax:
    <prefix>TIC MARK LABEL FORMAT <format>
    where
                no prefix refers to all 4 sides;
                the prefix X refers to both horizontal sides;
                the prefix Y refers to both vertical sides;
                the prefix X1 refers to the lower horizontal side;
                the prefix X2 refers to the upper horizontal side;
                the prefix Y1 refers to the left vertical side;
                the prefix Y2 refers to the right vertical side;
    and <format> is one of ALPHA/REAL/POWER/EXPO/GROUP LABEL as described in the DESCRIPTION section above.
Examples:
    TIC MARK LABEL FORMAT REAL
    TIC MARK LABEL FORMAT POWER
    TIC MARK LABEL FORMAT
    X2TIC MARK LABEL FORMAT ALPHA
    Y2TIC MARK LABEL FORMAT EXPONENTIAL
    X1TIC MARK LABEL CONTENT EXPONENTIAL
Note:
    A ...TIC MARK LABEL FORMAT command with no arguments reverts the setting to default; thus X1TIC MARK LABEL FORMAT with no arguments reverts the bottom horizontal tic label to the default format. A ...TIC MARK LABEL FORMAT command with no prefix refers to all 4 sides; thus TIC MARK LABEL FORMAT REAL sets tic mark labels to real for all 4 frame lines. TIC MARK LABEL FORMAT with no prefix and no arguments reverts the tic label format settings on all 4 sides to default.
Default:
    The tic mark labels for Linear scales are real numbers. The tic mark labels for log scales are drawn with the POWER format.
Synonyms:
    TIC LABEL FORMAT is a synonym for TIC MARK LABEL FORMAT, as in TIC LABEL FORMAT REAL and X2TIC LABEL FORMAT REAL.
Related Commands: Applications:
    Log scales, presentation graphics.
Implementation Date:
    1988/02
    2004/01: Added support for group labels, row labels and numeric variables to specify the contents of tic mark labels.
    2019/12: Added support for character variables to specify the contents of tic mark labels.
