如何将多个图表添加到一个Excel的不同工作表中？

2024-05-19 • 问答

我想将使用xlsxwriter创建的多个图表导出到一个Excel中的多个工作表中。我有两个数据框，如下所示：

df_a = pd.DataFrame({'User':['101','102','103','104','105','106'],'CountA':[7,8,9,10,11,12],'CountB':[1,2,3,4,5,6],'CountC':[13,14,15,16,17,18]})

df_b = pd.DataFrame({'User':['107','108','109','110','111','112'],'ValA':[10,20,30,40,50,60],'ValB':[70,80,90,100,110,120],'ValC':[130,140,150,160,170,180]})

我已经使用以下代码成功创建了一个excel文件，即“ test.xlsx”，其中包含df_a及其对应的堆叠条形图：

#Create a Pandas Excel writer using XlsxWriter as the engine.
 excel_file_a = 'test.xlsx'
 sheet_name_a = 'testA'

 writer = pd.ExcelWriter(excel_file_a,engine='xlsxwriter')
 df_a.to_excel(writer,sheet_name=sheet_name_a,index=False)

#access the XlsxWriter workbook and worksheet objects from the dataframe.
 workbook = writer.book
 worksheet_a = writer.sheets[sheet_name_a]

#Create a chart object.
 chart_a = workbook.add_chart({'type': 'column','subtype': 'stacked'})

#Configure the series of the chart from the dataframe data.
 for col_num in range(1,4):
     chart_a.add_series({
         'name':       ['testA',col_num],'categories': ['testA',1,0],'values':     ['testA',col_num,'gap':        2,})

#Insert the chart into the worksheet.
 worksheet_a.insert_chart('G2',chart_a)

#Close the Pandas Excel writer and output the Excel file.
 writer.save()

但是，我还希望df_b及其相应的堆叠条形图在同一excel文件“ test.xlsx”中，但在不同的工作表中，假设sheetname = testB。

这是使用循环的好地方。例如：

# You only need one of each of these
excel_file = 'test.xlsx'
writer = pd.ExcelWriter(excel_file_a,engine='xlsxwriter')
workbook = writer.book  
dataframes = (df_a,df_b)

# Loop through our list of dataframes
for i in range(len(dataframes)):
    sheet_name = 'test' + 'abcdefghijklmnop'[i]    # testa,testb,etc.
    dataframe = dataframes[i]

    dataframe.to_excel(writer,sheet_name=sheet_name,index=False)
    worksheet = writer.sheets[sheet_name]
    ....
    # all of the other stuff down as far as...
    worksheet.insert_chart('G2',chart)

# Now that we have finished our loop
writer.save()

我刚刚复制并粘贴了您的代码，并做了几件事。我不知道您的问题是什么，也许您正在覆盖某些内容。

    excel_file_a = 'test.xlsx'
    sheet_name_a = 'testA'
    sheet_name_b = 'testB'

    writer = pd.ExcelWriter(excel_file_a,engine='xlsxwriter')

    df_a.to_excel(writer,sheet_name=sheet_name_a,index=False)
    df_b.to_excel(writer,sheet_name=sheet_name_b,index=False)

    workbook = writer.book
    worksheet_a = writer.sheets[sheet_name_a]
    worksheet_b = writer.sheets[sheet_name_b]

    chart_a= workbook.add_chart({'type': 'column','subtype': 'stacked'})
    chart_b= workbook.add_chart({'type': 'column','subtype': 'stacked'})

    for col_num in range(1,4):
          chart_a.add_series({
             'name':       ['testA',col_num],'categories': ['testA',1,5,0],'values':     ['testA',col_num,'gap':        2,})

    for col_num in range(1,4):
          chart_b.add_series({
             'name':       ['testB','categories': ['testB','values':     ['testB',})

    worksheet_a.insert_chart('G2',chart_a)
    worksheet_b.insert_chart('G3',chart_b)

    writer.save()
