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]'
1
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.

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')
