ggplot2中的颜色和线条样式-Java 学习之路

-3

我想在ggplot2中的一个图上显示5组，如示例HERE所示 . 但是我不知道如何指定每个组在ggplot2设置中获得不同的颜色以及不同的阴影？因此，例如在图像中，红色是组A，蓝色是组B.实线是女性，虚线是男性 . 黄色是参考组 . 谢谢！

Data

# random example
df <- structure(list(time = c(1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 
    1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 1L, 2L, 3L, 4L, 5L, 
    6L, 7L, 8L, 9L, 10L, 1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 
    1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L), group = c("A", "A", 
    "A", "A", "A", "A", "A", "A", "A", "A", "B", "B", "B", "B", "B", 
    "B", "B", "B", "B", "B", "C", "C", "C", "C", "C", "C", "C", "C", 
    "C", "C", "D", "D", "D", "D", "D", "D", "D", "D", "D", "D", "E", 
    "E", "E", "E", "E", "E", "E", "E", "E", "E"), value = c(3L, 3L, 
    8L, 5L, 4L, 4L, 9L, 6L, 7L, 4L, 5L, 2L, 6L, 8L, 6L, 7L, 6L, 2L, 
    4L, 10L, 3L, 7L, 3L, 2L, 8L, 6L, 5L, 3L, 1L, 7L, 6L, 9L, 7L, 
    4L, 6L, 4L, 7L, 6L, 7L, 7L, 3L, 4L, 10L, 2L, 7L, 10L, 7L, 8L, 
    10L, 3L)), row.names = c(NA, -50L), .Names = c("time", "group", 
    "value"), class = "data.frame")

Plot

您可以使用 scale_color_manual 和 scale_linetype_manual 手动control colour and line type . 对于line type，您也可以使用数字：0 =空白，1 =实心，2 =虚线，3 =点，4 = dotdash，5 = longdash，6 = twodash .

library(ggplot2)
ggplot(data = df) +
  geom_line(aes(
    x = time ,
    y = value,
    colour = group,
    linetype = group
  )) +
  scale_color_manual(values = c(
    A = "red",
    B = "blue",
    C = "green",
    D = "yellow",
    E = "violet"
  )) +
  scale_linetype_manual(values = c("twodash","dotted","solid", "dashed", "longdash"))
