存入excel

# print('行数:',rowNum,'列数：',col,'数据：',data)

            workbook.save('/Users/clairyang/PycharmProjects/untitled/test/qunaer.xlsx')

从excel读取写成📈图表

workfile = xlrd.open_workbook('/Users/clairyang/PycharmProjects/untitled/test/qunaer.xlsx')

sheet= workfile.sheets()[0]#横行titleArr

    titleArr = sheet.col_values(0)

numArr = sheet.col_values(2)#售卖数量

priceArr = sheet.col_values(4)

plt.rcParams['font.sans-serif']='SimSun'

    plt.title("去哪数据分析")

plt.plot(numArr,titleArr,'go-',label='销量',linewidth=2)

plt.plot(priceArr,titleArr,'rs',label='价格')

plt.show()

或者展示成柱图

plt.title("去哪数据分析")

plt.bar(titleArr,numArr,color='rgb')

plt.gcf().autofmt_xdate()

plt.xlabel('景点名')

plt.ylabel('销量')

plt.savefig('景点销量榜')

plt.show()
