ggplot2的图例系统函数比较分散,在所有标度调整函数(轴标度除外)内部留有guide参数,可以通过guide_colorbar()、guide_legend()两个封装函数来进行图例自定义,但是因为guide_colorbar()、guide_legend()这两个函数也是巨无霸,直接写在scale_xxx这种本身就是巨无霸的函数内部,整个代码简直不堪重负。
p+guides(color=guide_colorbar(order=0),fill=guide_legend(order=0))p+guides(color=guide_colorbar(order=0),fill=guide_legend(order=1)) 如果我们要改变图例顺序,按下面的操作,将color变成1,然后fill使用默认排序: 代码语言:javascript 复制 # And we can reverse the order ...
