我从下表读取了从read_csv中读取的数据帧df5，

我想绘制2个100％堆叠的条形图，分别表示已售出的产品总数和利润总额，其中x轴是工作日，标签是不同的类别。

我的总销售商品代码是

df5 = df5.set_index(['Week_Days', 'Category'])
df5 = df5.div(df5.sum(1), axis=0)
ax = df5[['Total_Products_Sold']].plot(kind='bar', stacked=True, width = 0.3, figsize=(20, 10), colormap="RdBu")
patches, labels = ax.get_legend_handles_labels()
ax.legend(bbox_to_anchor=(1.1, 1.0))
ax.set_xlabel('Week Days')
ax.set_ylabel('Products Sold')

我返回的图看起来不需要任何东西。它不是堆叠的100，图例是“已售产品总数”，不是“类别”中的不同类别。

有人可以帮忙吗？谢谢。

问候，罗比

最简单的方法是使用您关心的值制作数据透视表。尝试这样的事情：

tps = df5.pivot_table(values=['Total_Products_Sold'], 
                      index='Week_Days',
                      columns='Category',
                      aggfunc='sum')

tps = tps.div(tps.sum(1), axis=0)
tps.plot(kind='bar', stacked=True)

对我来说，这产生了以下内容：
