我正在尝试在同一图表上绘制多年数据和平均值。我希望平均线（avg）和标准差（StdH和StdL）采用更粗的线型，以使其更加突出。
我已经到了可以用不同颜色和线型绘制它们的地步，但是我的编码似乎并没有专门针对scale_size_manual（）-即使当我获得其他手动比例以相同的方式工作时。它只是不适用或更改任何内容？？我不确定我的语法是否略有偏离？
任何帮助将不胜感激。
代码：
p1 <- ggplot(example, aes(x=day, y=value, colour = variable, shape=variable, linetype = variable,
fill = variable))
p1 <- p1 +geom_line()
p1 <- p1 + scale_shape_manual(name= "", values=
c(21,21,21,21,21,21,21,21,21,21),labels = c("2012", "2013", "2014", "2015",
"2016", "2017", "2018", "Avg", "StdH" , "StdL")) +
scale_linetype_manual(name= "", values= c("solid","solid","solid","solid","solid", "solid", "solid",
"solid","dotted", "dotted" ),
labels = c("2012", "2013", "2014", "2015",
"2016", "2017", "2018", "Avg","StdH" , "StdL")) +
scale_color_manual(name= "",values = c("lightpink1", "firebrick2", "red",

scale_size_manual(name= "",values =
c(0.5,0.5,0.5,0.5,0.5,0.5,0.5,3,1,1),labels = c("2012", "2013", "2014",
