The equation r= 4 \cos \theta represents a circle. Find the Cartesian coordinates of the center: x= \;\rule{20mm}{1pt} y= \; \rule{20mm}{1pt} and the radius : r = \; \rule{20mm}{1pt} How to find cartesian equation of a circle?
发现一个问题,条形图的堆叠顺序(A,B,C)与图例顺序(C,B,A)恰好相反,这个问题该如何处理呢?很简单,只需再添加guides()函数进行设置即可,如下所示: ggplot(data=df,mapping=aes(x=factor(x),y=z,fill=y))+geom_bar(stat='identity',position='stack')+guides(fill=guide_legend(reverse=TRUE)) ...
