GGPLOT问题；代码将线路绘制为一些非常奇怪的条。为什么这是？

在绘制来自数据框架的一些数据时，我有一些问题。它似乎将多个系列视为同一行。有人知道为什么这是吗？

dataframe代码创建df：

df <- read.table(text="Date     Item            Purchased
01/01/08 Fruit              48
01/01/08 Confectionary      42
01/01/08 Appliance          11
01/06/08 Confectionary      16
01/06/08 Fruit              19
01/06/08 Appliance          50", header=TRUE)

我要绘制数据

test_df <- ggplot(df)+geom_line(aes(x=Date, y=Purchased, color=Item, group = 1),size=8)+
  theme(title=element_text(size=10),panel.background = element_rect(fill='white'),legend.position='top')+geom_hline(yintercept = 0,color="white")

test_df

的代码：我的绘图结果：

我想绘制一些时间这些数据系列； “水果”的一条线，一个用于“糖果”的行，另一个用于“设备”。有人知道为什么这样做吗？

*编辑：添加x = lubridate :: mdy（date）产生您以下结果：

I'm having a bit of a problem when it comes to plotting some data from a dataframe. It seems to treat multiple series as being the same line. Does anyone know why this is?

Dataframe code to create df:

df <- read.table(text="Date     Item            Purchased
01/01/08 Fruit              48
01/01/08 Confectionary      42
01/01/08 Appliance          11
01/06/08 Confectionary      16
01/06/08 Fruit              19
01/06/08 Appliance          50", header=TRUE)

My code to plot data:

test_df <- ggplot(df)+geom_line(aes(x=Date, y=Purchased, color=Item, group = 1),size=8)+
  theme(title=element_text(size=10),panel.background = element_rect(fill='white'),legend.position='top')+geom_hline(yintercept = 0,color="white")

test_df

This result of my plot:

I'd like to plot some time series of this data; one line for 'Fruit', one for 'Confectionary' and one for 'Appliance'. Does anyone know why it's doing this?

*EDIT: Adding x=lubridate::mdy(Date) produces thee following result:
