Set Subcommand

For text written on a plot (TEXT, LEGEND, TITLE, LABEL commands), support the use of tabs denoted by the TAB() character sequence.

In some cases, plots may be annotated with a descriptive table. We may want to have columns in this table where the different columns may have different attributes.

In addition to the horizontal position, you can set the vertial position, the color, the justification, the font, the units (i.e., screen units or units of the most recent plot, and the size.

Tabs must be identified by the character sequence TAB(). Hard coded tab characters are converted to a single space on Dataplot command lines before Dataplot parses the command. Up to 10 tab settings can be specified.

SET TAB HORIZONTAL POSITION <index> <xcoor>
where <index> is a number or parameter in the range 1 to 10;
and     <xcoor> is number or parameter that defines the x-coordinate for the text following the tab identified by <index>.

SET TAB VERTICAL POSITION <index> <ycoor>
where <index> is a number or parameter in the range 1 to 10;
and     <ycoor> is number or parameter that defines the y-coordinate for the text following the tab identified by <index>.

SET TAB COLOR <index> <color>
where <index> is a number or parameter in the range 1 to 10;
and     <color> is literal value that defines the color for the text following the tab identified by <index>.

If the color is defined by a string, then do something like the following

LET STRING S = BLUE SET TAB COLOR 1 ^S

SET TAB JUSTIFICATION <index> <just>
where <index> is a number or parameter in the range 1 to 10;
and     <just> is literal value that defines the justification for the text following the tab identified by <index>.

If the justification is defined by a string, then do something like the following

LET STRING S = CENTER SET TAB JUSTIFICATION 1 ^S

SET TAB FONT <index> <font>
where <index> is a number or parameter in the range 1 to 10;
and     <font> is literal value that defines the font for the text following the tab identified by <index>.

If the font is defined by a string, then do something like the following

LET STRING S = COMPLEX SET TAB FONT 1 ^S

SET TAB UNITS <index> <DATA/SCREEN>
where <index> is a number or parameter in the range 1 to 10;
and     <DATA/SCREEN> is literal value that specifies whether the the horizontal position for the text following the tab identified by <index> is specified in 0 to 100 screen units (SCREEN) or in units of the most recent plot (DATA).


If the units are defined by a string, then do something like the following

LET STRING S = DATA SET TAB FONT 1 ^S

SET TAB VERTICAL UNITS <index> <DATA/SCREEN>
where <index> is a number or parameter in the range 1 to 10;
and     <DATA/SCREEN> is literal value that specifies whether the the vertical position for the text following the tab identified by <index> is specified in 0 to 100 screen units (SCREEN) or in units of the most recent plot (DATA).

If the units are defined by a string, then do something like the following

LET STRING S = DATA SET TAB VERTICAL FONT 1 ^S

SET TAB SIZE <index> <value>
where <index> is a number or parameter in the range 1 to 10;
and     <xcoor> is number or parameter that defines the character size, in 0 to 100 screen units, for the text following the tab identified by <index>.

SET TAB WIDTH <index> <value>
where <index> is a number or parameter in the range 1 to 10;
and     <xcoor> is number or parameter that defines the character width, in 0 to 100 screen units, for the text following the tab identified by <index>.

This syntax only applies if a software font is being used.

SET TAB HORIZONTAL POSITION 1 25
SET TAB COLOR 1 BLUE
SET TAB SIZE 1 2.5
SET TAB JUSTIFICATION 1 RIGHT
SET TAB HORIZONTAL POSITION 2 35
SET TAB COLOR 2 RED
SET TAB SIZE 2 3
SET TAB JUSTIFICATION 2 LEFT
