在画图时，X轴顺序会乱跳
如何固定我要的顺序来呈现
d$Team1为我要的顺序
用d$Team2来转换确出现问题
图的呈现要日期分开 再依Team1的group产生
是哪边有出错呢
谢谢
d <- data.frame(Team1=c("Cowboys","Cowboys", "Giants", "Giants", "Eagles", "Ea
gles", "Redskins", "Redskins"), Win=c(20, 13, 9, 12,10, 13, 22, 12),Date=c("7/
25","7/26","7/25","7/26","7/25","7/26","7/25","7/26"))
d$Team2 <- factor(d$Team1, as.character(d$Team1))
ggplot(d, aes(x=Date,y=Win,fill=Team2))+ geom_bar( stat="identity")
