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:

``"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, 0, angle)`` A regular polygon with ``numsides``
|
||
|
|
sides, rotated by ``angle``.
|
||
|
|
``(numsides, 1, angle)`` A star-like symbol with ``numsides``
|
||
|
|
sides, rotated by ``angle``.
|
||
|
|
``(numsides, 2, angle)`` An asterisk with ``numsides`` sides,
|
||
|
|
rotated by ``angle``.
|
||
|
|
============================== ====== =========================================
|
||
|
|
|
||
|
|
``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)
|
||
|
|
|
||
|
