我想删除右侧的 20 号图例。下面是我的代码:
qplot(lingLocation[ind,ind_water_fountain]/lingLocation[ind,1],
lingLocation[ind,ind_soda]/lingLocation[ind,1],
color = lingLocation[ind,ind_frosting]/lingLocation[ind,1], size = 20) +
# opts(legend.position = "none") +
scale_colour_gradient("Frosting %", low = "blue", high = "red") +
ylab("Soda %") +
xlab("Water Fountain %")
谢谢!
