这篇文章主要介绍了matplotlib 画双轴子图无法显示 x-轴 坐标轴标签的讲解,通过具体代码讲解7889并且分析了matplotlib 画双轴子图无法显示 x-轴 坐标轴标签的讲解的详细步骤与相关技巧,需要的朋友可以参考下

本文实例讲述了matplotlib 画双轴子图无法显示 x-轴 坐标轴标签的讲解。分享给大家供大家参考文章查询地址https://www.b2bchain.cn/7889.html。具体如下:

主要问题
1.介绍
如题,画双轴子图不能显示 x-轴坐标轴标签,似乎 “双轴”与“子图”存在冲突有关,当前版本是 anaconda 3.7.4。比较奇葩的是 我家里的电脑,3.7.3 却没这个问题。但我把公司电脑换成 3.7.3 问题依旧,崩溃。

import pandas as pd import matplotlib.pyplot as plt  a = pd.date_range('2020-07-01','2020-07-20') b = [2,3,4,5,7,9,20,20,11,13,1,2,3,9,23,2,6,7,7,7] c = [0.20,0.1,0.13,0.1,0.2,0.3,0.9,0.23,0.2,0.6,0.7,0.7,0.7,0.2,0.3,0.4,0.5,0.7,0.9,0.2]  data = pd.DataFrame({'a':a,'b':b,'c':c})  data = data.groupby(['a'])['b','c'].sum()  nrow = 2 ncol = 1  fig = plt.figure(figsize=(ncol*10,nrow*4))  ax_1 = plt.subplot2grid((nrow, ncol), (0, 0), colspan=1, rowspan=1,facecolor = 'black') ax_2 = plt.subplot2grid((nrow, ncol), (1, 0), colspan=1, rowspan=1,facecolor = 'black')  data['b'].plot(ax = ax_1,color = 'r') data['c'].plot(ax = ax_1.twinx(),color = 'y')

2.只画双轴,正常显示

import pandas as pd import matplotlib.pyplot as plt  a = pd.date_range('2020-07-01','2020-07-20') b = [2,3,4,5,7,9,20,20,11,13,1,2,3,9,23,2,6,7,7,7] c = [0.20,0.1,0.13,0.1,0.2,0.3,0.9,0.23,0.2,0.6,0.7,0.7,0.7,0.2,0.3,0.4,0.5,0.7,0.9,0.2]  data = pd.DataFrame({'a':a,'b':b,'c':c})  data = data.groupby(['a'])['b','c'].sum()  nrow = 1 ncol = 1  fig = plt.figure(figsize=(ncol*10,nrow*4))  ax_1 = plt.subplot2grid((nrow, ncol), (0, 0), colspan=1, rowspan=1,facecolor = 'black') # ax_2 = plt.subplot2grid((nrow, ncol), (1, 0), colspan=1, rowspan=1,facecolor = 'black')  data['b'].plot(ax = ax_1,color = 'r') data['c'].plot(ax = ax_1.twinx(),color = 'y')

3.只画子图,也能正常显示

import pandas as pd import matplotlib.pyplot as plt  a = pd.date_range('2020-07-01','2020-07-20') b = [2,3,4,5,7,9,20,20,11,13,1,2,3,9,23,2,6,7,7,7] c = [0.20,0.1,0.13,0.1,0.2,0.3,0.9,0.23,0.2,0.6,0.7,0.7,0.7,0.2,0.3,0.4,0.5,0.7,0.9,0.2]  data = pd.DataFrame({'a':a,'b':b,'c':c})  data = data.groupby(['a'])['b','c'].sum()  nrow = 2 ncol = 1  fig = plt.figure(figsize=(ncol*10,nrow*4))  ax_1 = plt.subplot2grid((nrow, ncol), (0, 0), colspan=1, rowspan=1,facecolor = 'black') ax_2 = plt.subplot2grid((nrow, ncol), (1, 0), colspan=1, rowspan=1,facecolor = 'black')  data['b'].plot(ax = ax_1,color = 'r') data['c'].plot(ax = ax_2,color = 'y')
