Virtually every ploticus attribute that produces text has an accompanying textdetails
specification for controlling appearance details such as point size, color, etc.
Text capabilities vary depending on what output format you're producing. See
fonts
for more information.
Examples
Prefab example: titledet="size=12 adjust=0,0.2"
Script example: titledetails: size=12 adjust=0,0.2
Note that settings are separated from each other by space, but settings
themselves contain no embedded whitespace. Also, the entire specification
must be on one line.
Settings
size=p
Point size of the text. 10 point is standard. A point is 1/72th of an inch.
style=s
Style font variant. s may be either
B for bold, I for italic, BI for bold-italic,
or R for regular.
Has an effect only in certain graphics environments and cannot be combined with
the font= setting.
font=fontname
Use the font fontname.
Has an effect only in certain graphics environments and cannot be combined with
the style= subattribute. See
fonts
for more info.
If the font name you are specifying contains embedded whitespace, each whitespace character
must be encoded here using an exclamation point (!).
align=a
Alignment or justification. a may be either
left, center, and right (use the whole word or just
the first letter, upper or lower case). In versions 2.40+ the following are supported to get
text that tracks downward or upward at a slant: downdiagonal and updiagonal
and these work for any output type.
linesep=f
Allows control over line spacing when multi-line text is rendered.
Default is 1.0. An f > 1.0 makes lines further apart; f < 1.0 makes lines closer together.
New in version 2.32.
adjust=x,y
color=
color
slantparm=h
If using align=downdiagonal or align=updiagonal to do X axis stubs,
this parameter can be used to control the amount of slant. It is the amount to move vertically
for every character, expressed as a proportion of text height. Default is 0.3; a value of 0.2 gives
a shallower slant, a value of 0.4 gives a steeper slant.
