1. 目前有四种主题
theme_gray(), theme_bw() , theme_minimal(),theme_classic()
2. X轴设置刻度
scale_x_continuous(limits=c(1950,2000),breaks=seq(1950,2000,5))
3. Bar & Line
ggplot2()+geom_bar(aes(y=x,fill=factor(Group.2)),stat="identity",position=‘dodge‘)+scale_x_continuous(limits=c(38,50),breaks=seq(38,50,1)) + geom_line(position="identity",aes(y=x))
4. ggplot - pie
ggplot(wm,aes(x="",fill=Type)) + geom_bar(width=1) + coord_polar(theta=‘y‘) + facet_wrap(~Product.Version) + theme_gray()
