Text symbols
============

The :meth:`pygmt.Figure.plot` method allows to plot text symbols. Text is
normally placed with the :meth:`pygmt.Figure.text` method but there are times
we wish to treat a character or even a string as a plottable symbol.
A text symbol can be drawn by passing **l**\ *size*\ **+t**\ *string* to
the ``style`` parameter where *size* defines the size of the text symbol
(note: the size is only approximate; no individual scaling is done for
different characters) and *string* can be a letter or a text string
(less than 256 characters). Optionally, you can append
**+f**\ *font,outlinecolor* to select a particular font [Default is
:gmt-term:`FONT_ANNOT_PRIMARY`] and outline color [Default is black] as well
as **+j**\ *justify* to change the justification [Default is CM]. The fill
color of the text symbols can be set with the ``fill`` parameter, and the
outline width can be customized with the ``pen`` parameter.
For all supported octal codes and fonts see the GMT Technical Reference
:gmt-docs:`reference/octal-codes.html` and
:gmt-docs:`reference/postscript-fonts.html`.
