"""

This module contains functions to handle markers. Used by both the

marker functionality of `~matplotlib.axes.Axes.plot` and

`~matplotlib.axes.Axes.scatter`.

All possible markers are defined here:

============================== ====== =========================================

marker symbol description

============================== ====== =========================================

``"."`` |m00| point

``","`` |m01| pixel

``"o"`` |m02| circle

``"v"`` |m03| triangle_down

``"^"`` |m04| triangle_up

``"<"`` |m05| triangle_left

``">"`` |m06| triangle_right

``"1"`` |m07| tri_down

``"2"`` |m08| tri_up

``"3"`` |m09| tri_left

``"4"`` |m10| tri_right

``"8"`` |m11| octagon

``"s"`` |m12| square

``"p"`` |m13| pentagon

``"P"`` |m23| plus (filled)

``"*"`` |m14| star

``"h"`` |m15| hexagon1

``"H"`` |m16| hexagon2

``"+"`` |m17| plus

``"x"`` |m18| x

``"X"`` |m24| x (filled)

``"D"`` |m19| diamond

``"d"`` |m20| thin_diamond

``"|"`` |m21| vline

``"_"`` |m22| hline

``0`` (``TICKLEFT``) |m25| tickleft

``1`` (``TICKRIGHT``) |m26| tickright

``2`` (``TICKUP``) |m27| tickup

``3`` (``TICKDOWN``) |m28| tickdown

``4`` (``CARETLEFT``) |m29| caretleft

``5`` (``CARETRIGHT``) |m30| caretright

``6`` (``CARETUP``) |m31| caretup

``7`` (``CARETDOWN``) |m32| caretdown

``8`` (``CARETLEFTBASE``) |m33| caretleft (centered at base)

``9`` (``CARETRIGHTBASE``) |m34| caretright (centered at base)

``10`` (``CARETUPBASE``) |m35| caretup (centered at base)

``11`` (``CARETDOWNBASE``) |m36| caretdown (centered at base)

``"None"``, ``" "`` or ``""`` nothing

``'$...$'`` |m37| Render the string using mathtext.

E.g ``"$f$"`` for marker showing the

letter ``f``.

``verts`` A list of (x, y) pairs used for Path

vertices. The center of the marker is

located at (0,0) and the size is

normalized, such that the created path

is encapsulated inside the unit cell.

path A `~matplotlib.path.Path` instance.

``(numsides, style, angle)`` The marker can also be a tuple

``(numsides, style, angle)``, which

will create a custom, regular symbol.

``numsides``:

the number of sides

``style``:

the style of the regular symbol:

- 0: a regular polygon

- 1: a star-like symbol

- 2: an asterisk

- 3: a circle (``numsides`` and

``angle`` is ignored);

deprecated.

``angle``:

the angle of rotation of the symbol

============================== ====== =========================================

For backward compatibility, the form ``(verts, 0)`` is also accepted, but it is

deprecated and equivalent to just ``verts`` for giving a raw set of vertices

that define the shape.

``None`` is the default which means 'nothing', however this table is

referred to from other docs for the valid inputs from marker inputs and in

those cases ``None`` still means 'default'.

Note that special symbols can be defined via the

:doc:`STIX math font </tutorials/text/mathtext>`,

e.g. ``"$\u266B$"``. For an overview over the STIX font symbols refer to the

`STIX font table <http://www.stixfonts.org/allGlyphs.html>`_.

Also see the :doc:`/gallery/text_labels_and_annotations/stix_fonts_demo`.

Integer numbers from ``0`` to ``11`` create lines and triangles. Those are

equally accessible via capitalized variables, like ``CARETDOWNBASE``.

Hence the following are equivalent::

plt.plot([1,2,3], marker=11)

plt.plot([1,2,3], marker=matplotlib.markers.CARETDOWNBASE)
