在多个geom plot中抑制来自特定geom的图例

Question

我有一个情节（下面），我试图控制传说。麻烦的是，我有geom_line(aes(linetype = season))和geom_bar(aes(linetype = season))。我想显示geom_line的图例（如下面的图1所示），而不是geom_bar的图例（如下面的图2所示）。

如果我尝试使用scale_linetype(guide = F)，则会关闭两者的图例。有没有办法显示geom_line线型而不是geom_bar线型的图例？下面是生成图表的代码。

为什么呢？最终，我希望条形的轮廓与线条相匹配，并带有精美的图例。你可以看到情节2几乎就在那里，但传说是难以辨认的

# code for plot 1
ggplot() +
  geom_line(data = temp, aes(pos, res, linetype = season)) +
  geom_bar(data = temp2, aes(depth, res, fill = season), 
           stat = "identity", position = "dodge", color = "black") +
  scale_fill_manual(values = c("white", "black"), guide = F) 

# code for plot 2
ggplot() +
  geom_line(data = temp, aes(pos, res, linetype = season)) +
  geom_bar(data = temp2, aes(depth, res, linetype = season, fill = season), 
           stat = "identity", position = "dodge", color = "black") +
  scale_fill_manual(values = c("white", "black"), guide = F)  

Answer 1

在评论中由joran回答。在geom_bar调用中使用了show_guide，代码如下所示

# plot 3
ggplot() +
  geom_line(data = temp, aes(pos, res, linetype = season)) +
  geom_bar(data = temp2, aes(depth, res, linetype = season, fill = season), 
           stat = "identity", position = "dodge", color = "black",
           show_guide = F) +
  scale_fill_manual(values = c("white", "black"))
