Question

我需要绘制一些东西，我的数据可以在previous post中获得，这对我处理ggplot2有很大帮助。（在上一篇文章中，我需要通过变量miht.binned的分位数来分类下面的图，但是在正式布局中，我从没有该分箱变量的更简单的绘图开始。）

我目前最好的情节版本是： enter image description here

我几乎感到满意，除了点，线和条似乎不一致重叠。特别是，当你看到T1的负面组时，它被黑线覆盖，看起来不太专业。有没有办法解决这个问题，并使重叠更加一致，有意义？该问题与导出格式无关（图像，pdf）。

该剧情的代码：

pd <- position_dodge(.2)
ggplot(MyData, aes(x=time, y=ias, colour=GROUP, group=GROUP, 
                                 shape=GROUP)) + 
  stat_summary(fun.data = "mean_se", geom="errorbar",position=pd) +
  stat_summary(fun.y="mean", geom="point", size=8,position=pd) + 
  stat_summary(fun.y="mean", geom="line",position=pd) + 
  scale_x_discrete(breaks=c("0", "1", "2"), labels=c("T0", "T1", "T2"))+
  coord_cartesian(ylim=c(2, 7)) + 
  scale_y_continuous(breaks=seq(2, 6, 2)) +
  scale_color_manual(values=c("gray30", "gray50","gray70"),name  ="Gruppe",
                                           breaks=c("baseline", "negative", "neutral"),
                                            labels=c("Baseline", "Attend-negative", "Attend-neutral")) +
  scale_shape_discrete(name  ="Gruppe",
                       breaks=c("baseline", "negative", "neutral"),
                       labels=c("Baseline", "Attend-negative", "Attend-neutral")) +
  theme(
    panel.grid.major.y = element_line(colour = "gray80", size = NULL, linetype = NULL,  # horizontale Linien
                                      lineend = NULL)
    ,panel.grid.minor.y = element_line(colour = "gray90", size = NULL, linetype = NULL,
                                       lineend = NULL)
    ,panel.grid.major.x = element_blank()           # vertikale Linien
    ,panel.grid.minor.x = element_blank()
    ,legend.background = element_rect(fill = "white", colour = "white") # Legende 
    ,legend.key = element_rect(fill = "white", colour = "white")
    ,panel.background = element_rect(fill = "white", colour = "white", size = NULL, # Panel Hintergrund
                                     linetype = NULL)
    ,axis.line = element_line(colour = "black", size=.5)
    ,axis.ticks.x = element_line(colour = "black", size=.5)
    ,axis.ticks.y = element_line(colour = "black", size=.5)
    ,axis.ticks.length =  unit(0.5, "cm")
    ,axis.ticks.margin =  unit(.3, "cm")
    ,axis.title.x = element_text(family = NULL, face = "bold", size = 11,vjust=0.1)
    ,axis.title.y = element_text(family = NULL, face = "bold", size = 11,vjust=0.1)
    ,axis.text=element_text(colour="black")
    ,legend.title = element_text(family = NULL, face = "plain", size = 11)
    ,legend.text = element_text(family = NULL, face = "plain", size = 9)
  ) +
  xlab("Messzeitpunkt")+
  ylab("State-KA (M)")

只需按照您需要的顺序更改stat_summary()次调用的顺序（它们按照您在代码中调用的顺序在实际绘图中绘制） - 第一个错误栏，然后是行和点作为最后一个。

  + stat_summary(fun.data = "mean_se", geom="errorbar",position=pd) +
  stat_summary(fun.y="mean", geom="line",position=pd) + 
  stat_summary(fun.y="mean", geom="point", size=8,position=pd)
