在折线图中显示三个因素

Question

我正在尝试制作具有三个因素的折线图。另外，我想让我的图例标签有两个符号。

这是我尝试模仿的已发布示例。...

如您所见，每个标签都有两个符号，每个水平代表一个因素。此外，对于每个水平，同一因子在同一面板上显示两次，即具有两个不同水平的因子的品种。

我试图一次制作一个面板，稍后我将加入它们，并将图例放在上面的示例的顶部。

这是我尝试的开始。...

我在图表上有自己的观点，尽管我对如何使一条线穿过每个品种，显示错误条以及使图例与上面的示例相似感到困惑。我希望图例为每个品种有一个标签，但要有两个符号，一个用于涝渍符号，另一个用于非涝渍符号

library(Rmisc)
library(ggplot2)

tglf3 <- summarySE(yar, measurevar="form", groupvars=c("P","cultivar","Waterlogging"),na.rm=TRUE)

ggplot(tglf3, aes(x=P, y=form)) + 
geom_point(aes(colour = factor(Waterlogging),

geom_errorbar(aes(ymin=form-se, ymax=form+se),colour="black", width=.1,position=position_dodge(1)) 

Answer 1

这是否符合您的需求？

library(tidyverse)
tglf3 <- summarySE(yar, measurevar="form", groupvars=c("P","cultivar","Waterlogging"),na.rm=TRUE)

通常，使用dplyr::group_by可以解决点线配对：

tglf3 %>% 
  group_by(cultivar) %>% 
  ggplot(aes(x=P, y=form, colour=Waterlogging, shape=cultivar)) + 
  geom_errorbar(aes(ymin=form-se, ymax=form+se), colour="black", width=.6) +
  geom_point(size=3.5) +
  geom_line() +
  theme_classic() +
  theme(legend.position = 'top', legend.direction="vertical")

---

使用scale_x_manual进行更多格式化：

tglf3 %>% 
  unite(new, cultivar, Waterlogging, sep = ', ') %>% 
  group_by(new) %>% 
  ggplot(aes(x=P, y=form, colour=new, shape=new, linetype=new)) + 
  geom_errorbar(aes(ymin=form-se, ymax=form+se), colour="black", width=.6) +
  geom_line(color="black") + 
  geom_point(size=3.5) +
  scale_colour_manual(name = "Cultivar, Waterlogging",
                      labels = c("Riverina, Non-waterlogged", "Riverina, Waterlogged", "Yarloop, Non-waterlogged", "Yarloop, Waterlogged"),
                      values = c("blue", "red", "blue", "red")) +
  scale_shape_manual(name = "Cultivar, Waterlogging",
                     labels = c("Riverina, Non-waterlogged", "Riverina, Waterlogged", "Yarloop, Non-waterlogged", "Yarloop, Waterlogged"),
                     values = c(19, 19, 17, 17)) +
  scale_linetype_manual(name = "Cultivar, Waterlogging", values=c("longdash", "solid", "longdash", "solid")) +
  theme_classic() +
  theme(legend.position = 'top', legend.direction="vertical") +
  guides(color=guide_legend(ncol=2))

---

没有%>%：

tglf4 <- unite(data = tglf3, new, cultivar, Waterlogging, sep = ', ')
tglf5 <- group_by(.data = tglf4, new)

ggplot(tglf5, aes(x=P, y=form, colour=new, shape=new, linetype=new)) + 
geom_errorbar(aes(ymin=form-se, ymax=form+se), colour="black", width=.6) +
geom_line(color="black") + 
geom_point(size=3.5) +
scale_colour_manual(name = "Cultivar, Waterlogging",
                    labels = c("Riverina, Non-waterlogged", "Riverina, Waterlogged", "Yarloop, Non-waterlogged", "Yarloop, Waterlogged"),
                    values = c("blue", "red", "blue", "red")) +
scale_shape_manual(name = "Cultivar, Waterlogging",
                   labels = c("Riverina, Non-waterlogged", "Riverina, Waterlogged", "Yarloop, Non-waterlogged", "Yarloop, Waterlogged"),
                   values = c(19, 19, 17, 17)) +
scale_linetype_manual(name = "Cultivar, Waterlogging", values=c("longdash", "solid", "longdash", "solid")) +
theme_classic() +
theme(legend.position = 'top', legend.direction="vertical") +
guides(color=guide_legend(ncol=2))

使用facet_grid（使用伪造数据的示例）：

tglf3 %>% 
  mutate(
    form = form * 1.5
  ) %>% 
  bind_rows(tglf3, .id = 'species') %>% # Add fake data to the real data as an example
  mutate(
    species = case_when(species == 1 ~ 'O. sativus',
                        T ~ 'O. compressus')
  ) %>% 
  unite(new, cultivar, Waterlogging, sep = ', ') %>% 
  group_by(new) %>% 
  ggplot(aes(x=P, y=form, colour=new, shape=new, linetype=new)) + 
  geom_errorbar(aes(ymin=form-se, ymax=form+se), colour="black", width=.6) +
  geom_line(color="black") + 
  geom_point(size=3.5) +
  scale_colour_manual(name = "Cultivar, Waterlogging",
                      labels = c("Riverina, Non-waterlogged", "Riverina, Waterlogged", "Yarloop, Non-waterlogged", "Yarloop, Waterlogged"),
                      values = c("blue", "red", "blue", "red")) +
  scale_shape_manual(name = "Cultivar, Waterlogging",
                     labels = c("Riverina, Non-waterlogged", "Riverina, Waterlogged", "Yarloop, Non-waterlogged", "Yarloop, Waterlogged"),
                     values = c(19, 19, 17, 17)) +
  scale_linetype_manual(name = "Cultivar, Waterlogging", values=c("longdash", "solid", "longdash", "solid")) +
  theme_classic() +
  theme(legend.position = 'top', legend.direction="vertical") +
  guides(color=guide_legend(ncol=2)) +
  facet_grid(.~species)
