命令
scale_x_continue(breaks=c(1:20),labels=c(1:20),limits=c(1,20) ##limits设置区间大小，breaks设置刻度位置，labels设置刻度

命令
生成数据需要aes:geom_point(aes(shape=factor(d%2Ccolor%3Dfactor(d)
kind)),size=3)
修改text:
如果是通过fill分组，scale_fill_discrete(labels=c('interaction effect','main effect'))
如果是颜色，scale_color_discrete(labels=c('interaction effect','main effect'))
如果还有形状，还需要添加scale_shape_discrete(labels=c('interaction effect','main effect'))
以此类推
修改位置、大小、border、标题:
<pre>
theme(
##no legend.title
legend.title = element_blank(),
## legend border
legend.box.background = element_rect( size = 1),
##legend inside, change relative positions by 0.95, 0.95
legend.position = c(.95, .95),
legend.justification = c("right", "top"),
legend.box.just = "right",
legend.margin = margin(6, 6, 6, 6),
##legend text setting
legend.text = element_text(size = 15)
)
</pre>
