[英]matplotlib plot bar and line charts together
I want to plot bar and line together in one chart. 我想在一个图表中绘制条形图和线条。 When I plot bars, it displays correctly(g1 and g10 are displayed completed): 当我绘制条形图时,它会正确显示(g1和g10显示完成):
However, if I add a line to the plot: 但是,如果我在图中添加一条线:
m1_t[['abnormal','fix','normal']].plot(kind='bar')
m1_t['bad_rate'].plot(secondary_y=True)
The bar chart is incomplete as below(g1 and g10 are chopped): 条形图不完整如下(g1和g10被切碎):
Any idea how to fix this problem? 知道如何解决这个问题吗?
You have to expand x axis with xlim: 你必须用xlim扩展x轴:
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
width = .35 # width of a bar
m1_t = pd.DataFrame({
'abnormal' : [90,40,30,30,30,25,25,20,15,10],
'fix' : [60,70,65,70,70,60,50,45,45,45],
'normal' : [140,160,170,180,190,200,210,220,230,240],
'bad_rate' : [210,100,100,70,70,75,70,60,65,60]})
m1_t[['abnormal','fix','normal']].plot(kind='bar', width = width)
m1_t['bad_rate'].plot(secondary_y=True)
ax = plt.gca()
plt.xlim([-width, len(m1_t['normal'])-width])
ax.set_xticklabels(('G1', 'G2', 'G3', 'G4', 'G5', 'G6', 'G7', 'G8', 'G9', 'G10'))
plt.show()
For future question post your dataframe. 将来的问题发布到您的数据帧。
Try switching the order of plotting: 尝试切换绘图顺序:
ax = m1_t['bad_rate'].plot(secondary_y=True)
m1_t[['abnormal','fix','normal']].plot(kind='bar', ax=ax)
or preserve the original barchart xlim
: 或保留原始的条形图xlim
:
ax = m1_t[['abnormal','fix','normal']].plot(kind='bar')
m1_t['bad_rate'].plot(secondary_y=True, xlim=ax.get_xlim())
