This plot:

Is generated with the following code:

使用以下代码生成:

library(ggplot2)                  
df <- read.table("http://dpaste.com/1697602/plain/");
ggplot(df,aes(x=factor(1),y=V2,fill=V1))+
   geom_bar(width=1,stat="identity")+coord_polar(theta="y")

How can I remove the following:

如何删除以下内容:

1. Circular coordinate, e.g. (0, 10000, 20000,30000)

圆坐标,例如(0,10000,20000,30000)

2. Y axis coordinate (e.g. 1)

Y轴坐标(例如1)

3. White circle.

You may remove these elements by using relevant arguments in theme:

您可以通过在主题中使用相关参数来删除这些元素:

ggplot(df, aes(x = factor(1), y = V2, fill = V1))+
  geom_bar(width = 1, stat = "identity") +
  coord_polar(theta = "y") +
  theme(axis.text = element_blank(),
        axis.ticks = element_blank(),
        panel.grid  = element_blank())

After the entire grid is removed, you can manually add an own grid, using geom_hline and geom_vline (see here).

删除整个网格后,您可以使用geom_hline和geom_vline手动添加自己的网格(请参阅此处)。
