对于创建带有线型和颜色here和here的混合图例的问题，我发现了看似正确的解决方案。但是，我的代码仍然没有预期的效果，而是生成了一个图例，其中未考虑线型。我的目标是让我的传说与我的情节相符。
我从一个简单的scale_linetype_manual("",value = c(2,2,1,1,1))开始，并在下面的代码中停止尝试。
ggplot(data_norm_long, aes(x = as.integer(year), y = value, colour = variable, linetype = kat), group = "variable") +
geom_point() +
geom_line() +
scale_color_manual("",
breaks = c("LO_kat2","lean_kat2","hola_kat1","lean_kat1","LO_kat1"),
values = c(LO_kat2 = "darkblue", lean_kat2 = "darkgreen", hola_kat1 = "darkred", lean_kat1 = "darkgreen", LO_kat1 = "darkblue"),
labels = c("Label 1","Label 2","Label 3","Label 4","Label 5")) +
scale_linetype_manual("",
breaks = c("LO_kat2","lean_kat2","hola_kat1","lean_kat1","LO_kat1"),
values = c("1" = "solid", "2" = "dashed"))
