[Python3] Matplotlib.pyplot.plot图形符号、风格及颜色缩写速查表

Matplotlib.pyplot.plot图形符号、风格及颜色简写形式速查表

注：图形符号、风格及颜色均为plot函数的可选参数

• 如不指定符号和线条风格，默认为无符号的实线
• 如不指定颜色，Matplotlib会为多条线自动循环使用一组默认的颜色

Format Strings

A format string consists of a part for color, marker and line:

fmt = '[marker][line][color]'

Each of them is optional. If not provided, the value from the style cycle is used. Exception: If line is given, but no marker, the data will be a line without markers.

Other combinations such as [color][marker][line] are also supported, but note that their parsing may be ambiguous.

‘1’	tri_down marker
‘2’	tri_up marker
‘3’	tri_left marker
‘4’	tri_right marker
‘s’	square marker
‘p’	pentagon marker
‘*’	star marker
‘h’	hexagon1 marker
‘H’	hexagon2 marker
‘+’	plus marker

‘d’	thin_diamond marker
‘|’	vline marker
‘_’	hline marker

# 示例（按表格从上至下顺序展示线条）
plt.plot(x, x + 0, '4', label='4')
plt.plot(x, x + 1, '3', label='3')
plt.plot(x, x + 2, '2', label='2')
plt.plot(x, x + 3, '1', label='1')
plt.plot(x, x + 4, '>', label='>')
plt.plot(x, x + 5, '<', label='<')
plt.plot(x, x + 6, '^', label='^')
plt.plot(x, x + 7, 'v', label='v')
plt.plot(x, x + 8, 'o', label='o')
plt.plot(x, x + 9, ',', label=',')
plt.plot(x, x + 10, '.', label='.')
plt.legend(bbox_to_anchor=(1.05, 1), loc='upper left', borderaxespad=0.)

# 示例
plt.plot(x, x + 0, '_', label='_')
plt.plot(x, x + 1, '|', label='|')
plt.plot(x, x + 2, 'd', label='d')
plt.plot(x, x + 3, 'D', label='D')
plt.plot(x, x + 4, 'x', label='x')
plt.plot(x, x + 5, '+', label='+')
plt.plot(x, x + 6, 'H', label='H')
plt.plot(x, x + 7, 'h', label='h')
plt.plot(x, x + 8, '*', label='*')
plt.plot(x, x + 9, 'p', label='p')
plt.plot(x, x + 10, 's', label='s')
plt.legend(bbox_to_anchor=(1.05, 1), loc='upper left', borderaxespad=0.)

Line Styles 线条风格

character	description
‘-’	solid line style 实线
‘--’	dashed line style 虚线
‘-.’	dash-dot line style 点划线
‘:’	dotted line style 实点线

# 示例
plt.plot(x, x + 0, linestyle='-') # 实线
plt.plot(x, x + 1, linestyle='--') # 虚线
plt.plot(x, x + 2, linestyle='-.') # 点划线
plt.plot(x, x + 3, linestyle=':') # 实点线

Example format strings:

# 示例
plt.plot(x, x + 0, 'b', label='b')		# blue markers with default shape
plt.plot(x, x + 1, 'or', label='or') 	# red circles
plt.plot(x, x + 2, '-g', label='-g') 	# green solid line
plt.plot(x, x + 3, '--', label='--') 	# dashed line with default color
plt.plot(x, x + 4, '^k:', label='^k:')  	# black triangle_up markers connected by a dotted line
plt.legend(loc='lower right')

Colors 颜色

The supported color abbreviations are the single letter codes

character	color
‘b’	blue
‘g’	green
‘r’	red
‘c’	cyan 青色
‘m’	magenta 品红
‘y’	yellow
‘k’	black
‘w’	white 白色
