反折线图年份计数matplotlib

Question

我正在尝试创建三个不同组（即桌面、移动和平板电脑）的计数折线图，x轴为2014年、2015年和2016年，但我得到了错误

我的代码当前为：

#year-by-year change
desktop14 = od.loc[(od.Account_Year_Week >= 201401) & (od.Account_Year_Week <= 201453) & (od.online_device_type_detail == "DESKTOP"), "Gross_Demand_Pre_Credit"]
desktop15 = od.loc[(od.Account_Year_Week >= 201501) & (od.Account_Year_Week <= 201553) & (od.online_device_type_detail == "DESKTOP"), "Gross_Demand_Pre_Credit"]
desktop16 = od.loc[(od.Account_Year_Week >= 201601) & (od.Account_Year_Week <= 201653) & (od.online_device_type_detail == "DESKTOP"), "Gross_Demand_Pre_Credit"]
mobile14 = od.loc[(od.Account_Year_Week >= 201401) & (od.Account_Year_Week <= 201453) & (od.online_device_type_detail == "MOBILE"), "Gross_Demand_Pre_Credit"]
mobile15 = od.loc[(od.Account_Year_Week >= 201501) & (od.Account_Year_Week <= 201553) & (od.online_device_type_detail == "MOBILE"), "Gross_Demand_Pre_Credit"]
mobile16 = od.loc[(od.Account_Year_Week >= 201601) & (od.Account_Year_Week <= 201653) & (od.online_device_type_detail == "MOBILE"), "Gross_Demand_Pre_Credit"]
tablet14 = od.loc[(od.Account_Year_Week >= 201401) & (od.Account_Year_Week <= 201453) & (od.online_device_type_detail == "TABLET"), "Gross_Demand_Pre_Credit"]
tablet15 = od.loc[(od.Account_Year_Week >= 201501) & (od.Account_Year_Week <= 201553) & (od.online_device_type_detail == "TABLET"), "Gross_Demand_Pre_Credit"]
tablet16 = od.loc[(od.Account_Year_Week >= 201601) & (od.Account_Year_Week <= 201653) & (od.online_device_type_detail == "TABLET"), "Gross_Demand_Pre_Credit"]

devicedata = [["Desktop", desktop14.count(), desktop15.count(), desktop16.count()], ["Mobile", mobile14.count(), mobile15.count(), mobile16.count()], ["Tablet", tablet14.count(), tablet15.count(), tablet16.count()]]
df = pd.DataFrame(devicedata, columns=["Device", "2014", "2015", "2016"]).set_index("Device")


plt.show()

我想让每一行的设备类型和x轴显示在一年中的变化。我该怎么做-（基本上是反转轴）。你知道吗

非常感谢您的帮助

就这么做吧

df.transpose().plot()

结果如下：
