python绘制堆叠条形图介绍 python绘制堆叠条形图介绍

目前在网络上多是单个条形图堆叠，没看到一组的条形图堆叠。
代码如下：

import numpy as npimport pandas as pdimport matplotlib.pyplot as pltimport matplotlib.ticker as ticker

导入一组自己造的数据

data= https://www.it610.com/article/pd.read_excel('data.xlsx')In [4]: dataOut[4]:

多使用几个plt.bar()函数，就可以画出来啦。。。

tick_label = list(data.columns)tick_label.remove(‘类别')x = np.arange(len(tick_label))y1 = data.iloc[2,1:].values.tolist() #收入(剔除自己转入)y2 = data.iloc[3,1:].values.tolist() #支出(剔除自己转入)y3 = data.iloc[4,1:].values.tolist() #收入(自己转入)y4 = data.iloc[5,1:].values.tolist() #支出(自己转入)bar_with = 0.25 #柱体宽度plt.figure(figsize = (12,6)) #画布大小plt.bar(x, y1, width = bar_with, #柱体宽度align = ‘center', #x轴上的坐标与柱体对其的位置color = ‘orangered', alpha = 0.6, #柱体透明度label = ‘收入(剔除自己转入)')plt.bar(x,y3,width = bar_with, bottom = y1, #柱体基线的y轴坐标align = ‘center', color = ‘lightsalmon', alpha = 0.6, label = ‘收入(自己转入)')plt.bar(x + bar_with, y2, width = bar_with,align = ‘center', color = ‘deepskyblue', alpha = 0.6, label = ‘支出(剔除自己转入)')plt.bar(x + bar_with, y4, width = bar_with, bottom = y2,align = ‘center', color = ‘lightskyblue', alpha = 0.6, label = ‘支出(自己转入)')plt.title(‘月度收支表', fontsize = 10) #设置x轴标题plt.xticks(x + bar_with/2, tick_label, rotation = 70) #设置x轴坐标plt.xlabel(‘时间',fontsize = 8, verticalalignment = ‘top', horizontalalignment=‘right',rotation=‘horizontal')plt.xlabel(‘时间',fontsize = 8, verticalalignment = ‘bottom', horizontalalignment=‘center')#图例设在图形外面，控制坐标参数plt.legend(loc = ‘center', bbox_to_anchor = (0.77, 1.1), ncol=2)plt.savefig(‘draw_bar.png', dpi=200, bbox_inches = ‘tight')plt.close()
