fortplot_mathtext Module

Mathematical text rendering with superscripts and subscripts Supports matplotlib-like syntax: x^2, y_i, x_{text}, y^{superscript}

Uses

- iso_fortran_env
- fortplot_unicode

Derived Types

Components

Type	Visibility	Attributes		Name		Initial
character(len=:),	public,	allocatable	::	text
character(len=:),	public,	allocatable	::	denominator
integer,	public		::	element_type	=	ELEMENT_NORMAL
real(kind=wp),	public		::	font_size_ratio	=	1.0_wp
real(kind=wp),	public		::	vertical_offset	=	0.0_wp
logical,	public		::	italic	=	.false.	True for runs that originate inside a '$...$' math segment. matplotlib renders math variables in italic; backends apply a synthetic oblique shear to alphabetic glyphs of italic runs.
