本文介绍了在ggplot2中指定点的形状的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个带有Detect列的CSV，结果为Y或N.我有脚本来更改依赖于该列的形状，但我需要指定Y为实心圆，而N为空心圈.

I have a CSV with a Detect column where the result is Y or N. I've got my script to change shape dependent on that column, but I need to specify that Y is a filled in circle, while N is hollow circle.

library("ggplot2")
Report213 <- read.csv("FILE_NAME")
ggplot(data = Report213, aes(x = factor(Station_ID, level = c("NEB","NWB","LBC","WB","HR","FDP","FS","NR","PB")), y = Result,  Group = Detect,  colour = Station_ID,shape = Detect
)) + geom_point(aes(shape=Detect,size = 2)) +
facet_grid( . ~ Chemical ) +facet_wrap( ~ Chemical, scales= "free_y",ncol = 1) + theme(
panel.background = element_rect(fill = "white",
                            colour = "white",
                            size = 0.5, linetype = "solid"),
panel.grid.major = element_line(size = 0.5, linetype = 'solid',
                            colour = "gray"), 
panel.grid.minor = element_line(size = 0.25, linetype = 'solid',
                            colour = "white"),
strip.background =element_rect(fill="#454545"),
strip.text = element_text(colour = 'white')
)

欣赏所有指针.

推荐答案

您可以使用scale_shape_manual

P.S:不能同时使用facet_grid或facet_wrap

P.S: Use either facet_grid or facet_wrap not both at the same time

使用 ggplot2 v3.0.0 在2018年7月发布的版本中，您可以使用文本/字符串指定形状.例如. scale_shape_manual(values = c("circle", "circle open")).查看更多此处 

library(tidyverse)

Report213 <- Report213 %>% 
  mutate(Station_ID = factor(Station_ID, 
                             level = c("NEB","NWB","LBC","WB","HR","FDP","FS","NR","PB")))

ggplot(data = Report213, 
       aes(x = Station_ID, 
           y = Result)) + 
  geom_point(aes(color = Station_ID, shape = Detect), size = 2) +
  scale_shape_manual(values = c(19, 1)) +
  facet_wrap( ~ Chemical, scales = "free_y", ncol = 1) + 
  theme(
    panel.background = element_rect(fill = "white",
                                    colour = "white",
                                    size = 0.5, linetype = "solid"),
    panel.grid.major = element_line(size = 0.5, linetype = 'solid',
                                    colour = "gray"), 
    panel.grid.minor = element_line(size = 0.25, linetype = 'solid',
                                    colour = "white"),
    strip.background =element_rect(fill = "#454545"),
    strip.text = element_text(colour = 'white')
  )

添加string ~ integer形状表以供将来参考

Edit 2: Add string ~ integer shape table for future references

  pch_table <- c(
    "square open"           = 0,
    "circle open"           = 1,
    "triangle open"         = 2,
    "plus"                  = 3,
    "cross"                 = 4,
    "diamond open"          = 5,
    "triangle down open"    = 6,
    "square cross"          = 7,
    "asterisk"              = 8,
    "diamond plus"          = 9,
    "circle plus"           = 10,
    "star"                  = 11,
    "square plus"           = 12,
    "circle cross"          = 13,
    "square triangle"       = 14,
    "triangle square"       = 14,
    "square"                = 15,
    "circle small"          = 16,
    "triangle"              = 17,
    "diamond"               = 18,
    "circle"                = 19,
    "bullet"                = 20,
    "circle filled"         = 21,
    "square filled"         = 22,
    "diamond filled"        = 23,
    "triangle filled"       = 24,
    "triangle down filled"  = 25
)
