`\"D\"`	$\"m19\"$	diamond
`\"d\"`	$\"m20\"$	thin_diamond
`\"	\"`	$\"m21\"$
`\"_\"`	$\"m22\"$	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)

`\"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 `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`.

代码实例

1. 导入包

import matplotlib.pyplot as plt
import random

2. 生成随机数

random.seed(2022)
y = [random.gauss(0, 1) for i in range(10)]
x = range(10)
print(y)
# [-1.059911532796699, -0.21343209892227447, -0.13048724278481846, 0.3292493351854598, 
# 0.5945395388166395, -2.772070654427417, -1.2083544534018353, 0.7418635616787197, 
# 0.7416186001053393, -1.8432987685720519]

3. 画图

fig, ((ax1, ax2), (ax3, ax4)) = plt.subplots(2, 2, figsize=(12, 6))

ax1.plot(x, y, marker=\'.\', color=\'r\') # marker=\'.\'
ax2.plot(x, y, marker=\',\', color=\'g\') # marker=\',\'
ax3.plot(x, y, marker=\',\', color=\'b\') # marker=\'1\'
ax4.plot(x, y, marker=\'D\', color=\'pink\') # marker=\'D\'
