#r #ggplot2

Вопрос:

Я хочу переместить направляющую слева от графика, переместить ее ближе к графику, я попробовал функцию legend.justification = c() в теме, но она не работает.

Я добавил в конце свои строки и структуру данных, я присвоил данные «plot_frame»:

Мой код для ggplt:

 legend1 <- ggplot(plot_frame, aes(Var2, Var1))  
  geom_point(data = data.frame(Var2 = 1:4, Var1 = 0, value = 0), size = 5,
           aes(color = factor(Var2)))  
  geom_point(data = data.frame(Var2 = 1:4, Var1 = 0, value = 1), alpha = 0)  
  scale_color_manual(values = c("black", "forestgreen", "#DE2D29", "#3C57A8"),
                     labels = c(expression(
                         CD44^{lo}~"T Cells",
                         CD44^{hi}~CD69^{lo}~"T Cells",
                         CD44^{hi}~CD69^{hi}~CD103^{lo}~"T Cells",
                         CD44^{hi}~CD69^{hi}~CD103^{hi}~"T Cells")),
                     guide = guide_legend(override.aes = list(size = 3), 
                                          label.hjust = 0))   
theme (panel.grid = element_blank(), 
       axis.text.y.right = element_text(margin = margin(l = unit(-5, "cm"))),
       axis.text.y = element_text(face="italic", size=5, 
                                 color="black"),
       legend.justification = c(-0.5, 0),
       legend.direction = "vertical",
       legend.key = element_blank(),
       legend.title = element_blank(),
       axis.text.x = element_blank())

Как этого добиться?
