Matplotlib 图表的样式参数
1.
import numpy as np import pandas as pd import matplotlib.pyplot as plt % matplotlib inline # 导入相关模块 # linestyle参数 plt.plot([i**2 for i in range(100)], linestyle = '-.') #不用设置的时候默认为直线‘-’ # '-' solid line style # '--' dashed line style # '-.' dash-dot line style # ':' dotted line style
输出：
[<matplotlib.lines.Line2D at 0x1e1348c8550>]
2.
df = pd.DataFrame(np.random.randn(1000)) df.plot(kind = 'kde',linestyle = '--') #绘制密度图 df.hist() #绘制直方图
输出：
array([[<matplotlib.axes._subplots.AxesSubplot object at 0x00000185B8B0ADA0>]], dtype=object)
3.
# marker参数 s = pd.Series(np.random.randn(100).cumsum()) s.plot(linestyle = '--',linewidth = 1, marker = 'x') #图中点的风格设置 默认为‘.’ linwidth为线宽 即线的粗细 # '.' point marker # ',' pixel marker # 'o' circle marker # 'v' triangle_down marker # '^' triangle_up marker # '<' triangle_left marker # '>' triangle_right marker # '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 # 'x' x marker # 'D' diamond marker # 'd' thin_diamond marker # '|' vline marker # '_' hline marker
