shape样式：

02geom_smooth

ggplot(data =....) +

geom_smooth(aes(x =..., y =..., color =(类别)..., linetype =..., group =...,), color =..., size =..., linetype =..., method ="lm",..., formula =..., se = TRUE(展示confidence interval)) + ...

03geom_line

分组线条：

ggplot(data =....) +

geom_line(aes(x =..., y =..., color =(类别)..., linetype =..., group =...,), color =..., size =..., alpha =..., linetype ="...") + ...

linetype样式：

特定多组线条：

ggplot(data =...., aes(x =...)) +

geom_line(aes(y =..., color =(标签名称)...), size =..., linetype =...) +

geom_line(aes(y =..., color =(标签名称)...), size =..., linetype =...) +

scale_color_brewer(name =..., palette =...) + ...

04geom_bar

12geom_vline/hline/abline

ggplot(data =....) +

geom_hline(yintercept =..., linetype =..., color =..., size =...) /

geom_vline(xintercept =..., linetype =..., color =..., size =...) /

geom_abline(intercept =..., slope =..., linetype =..., color =..., size =...) / + ...

1修改坐标轴

离散型：

scale_x_discrete("坐标轴名称", labels=c("..."="...",...), limits =c(...), breaks =c(...))

连续型：

scale_x_continuous("坐标轴名称",labels=c(...),limits =c(...), breaks =c(...))

library(scale)

scale_x_date(breaks=date_break("1 year"), limits=as.Date(c(...)), labels=date_format("%Y-%m-%d"))

2修改颜色

离散型：

scale_color_manual("图例名称", values =c("名称" = "颜色",...)

scale_fill_manual("图例名称", values =c("名称" = "颜色",...)

scale_color_brewer(name="...", palette ="...")

scale_fill_brewer(name="...", palette ="...")

palette样式：

连续型：

scale_color_gradient(low="...", high ="...")

scale_fill_gradient(limits =c(...), low ="...", high ="...")

scale_fill_gradient2(low ="...", high ="...", mid ="...", midpoint =...)

3字体、位置、排版等修改

四种方程：

element_text(size =..., color =..., face ="bold", angle =..., hjust =..., vjust =...,)

element_line(size =..., color =..., linetype= ...)

element_rect(size =..., color =..., linetype= ..., fill =...)

element_blank()

4主题

5分面

6其他

放大zooming：

coord_cartesian(xlim =c(,), ylim =c(,), expand =TRUE, default =FALSE, clip ="on")

加标题快捷法：

labs(x ="...", y ="...", title ="...")

坐标轴互换：

coord_flip()

图例位置：

theme(legend.position ="top","bottom","left","right")

添加任意方程：

stat_function(fun =..., args =list(,), color =..., size =...)
