Matplotlib.pyplot.plot图形符号、线条风格及颜色简写形式速查表
注：图形符号、线条风格及颜色均为
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:
1 | 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.

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 |
1 2 3 4 5 | # 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:
1 2 3 4 5 6 7 | # 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') |
