Handle storing and drawing of text in window or data coordinates.
Create a
Text
instance atx,y with stringtext.The text is aligned relative to the anchor point (x,y) accordingto
horizontalalignment
(default: 'left') andverticalalignment
(default: 'baseline'). See alsoText alignment.While Text accepts the 'label' keyword argument, by default it is notadded to the handles of a legend.
Valid keyword arguments are:

Return the
Bbox
bounding the text, in display units.In addition to being used internally, this is useful for specifyingclickable regions in a png file on a web page.
- Parameters:
- rendererRenderer, optional
A renderer is needed to compute the bounding box. If the artisthas already been drawn, the renderer is cached; thus, it is onlynecessary to pass this argument when calling
get_window_extent
before the first draw. In practice, it is usually easier totrigger a draw first, e.g. by callingdraw_without_rendering
orplt.show()
.- dpifloat, optional
The dpi value for computing the bbox, defaults to
self.get_figure(root=True).dpi
(not the renderer dpi); should be sete.g. if to match regions with a figure saved with a custom dpi value.

Annotate the pointxy with texttext.
In the simplest form, the text is placed atxy.
Optionally, the text can be displayed in another positionxytext.An arrow pointing from the text to the annotated pointxy can thenbe added by definingarrowprops.
- Parameters:
- textstr
The text of the annotation.
- xy(float, float)
The point(x, y) to annotate. The coordinate system is determinedbyxycoords.
- xytext(float, float), default:xy
The position(x, y) to place the text at. The coordinate systemis determined bytextcoords.
- xycoordssingle or two-tuple of str or
Artist
orTransform
or callable, default: 'data' The coordinate system thatxy is given in. The following typesof values are supported:
One of the following strings:
Value

'data'
Use the coordinate system of the objectbeing annotated (default)
'polar'
(theta, r) if not native 'data'coordinates
Note that 'subfigure pixels' and 'figure pixels' are the samefor the parent figure, so users who want code that is usable ina subfigure can use 'subfigure pixels'.
An
Artist
:xy is interpreted as a fraction of the artist'sBbox
. E.g.(0, 0) would be the lowerleft corner of the bounding box and(0.5, 1) would be thecenter top of the bounding box.A
Transform
to transformxy to screen coordinates.A function with one of the following signatures:
deftransform(renderer)->Bboxdeftransform(renderer)->Transform
whererenderer is a

- get_glyphs_mathtext(prop,s,glyph_map=None,return_new_glyphs_only=False)[source]#
Parse mathtext strings and convert it to a (vertices, codes) pair.
- get_glyphs_tex(prop,s,glyph_map=None,return_new_glyphs_only=False)[source]#
Convert the strings to vertices and codes using usetex mode.
- get_glyphs_with_font(font,s,glyph_map=None,return_new_glyphs_only=False)[source]#
Convert strings to vertices and codes using the provided ttf font.
- get_text_path(prop,s,ismath=False)[source]#
Convert texts to path (a tuple of vertices and codes formatplotlib.path.Path).
- Parameters:
- prop
FontProperties
The font properties for the text.
- sstr
The text to be converted.
- ismath{False, True, "TeX"}
If True, use mathtext parser. If "TeX", use tex for rendering.
- prop
- Returns:
- vertslist
A list of arrays containing the (x, y) coordinates of the vertices.
- codeslist
A list of path codes.
Examples
Create a list of vertices and codes from a text, and create a
Path
from those:frommatplotlib.pathimportPathfrommatplotlib.textimportTextToPathfrommatplotlib.font_managerimportFontPropertiesfp=FontProperties(family="Comic Neue",style="italic")verts,codes=TextToPath().get_text_path(fp,"ABC")path=Path(verts,codes,closed=False)
