多条线图，但我只想在一条特定线上显示文本和点

Question

所以我有这段代码可以绘制以下多条线图

grafico1 <- ggplot(dataset1, aes(x = V1, y = V3)) + 
  geom_line(aes(color = V2), size = 1) +
  scale_color_manual(values = c("#D2691E","#00FFFF","#228B22"))   +
  scale_x_continuous(breaks = round(seq(min(dataset1$V1), max(dataset1$V1)))) + geom_point()  +
geom_text(aes(label=V3), nudge_y = 1000)

看到它在所有行中绘制点和文本值。 所以我想要的是那些点和值文本只出现在蓝线上。

Answer 1

您可以使用以下方法使标签和点有条件：

ggplot(df, aes(x = V1, y = V3)) + 
  geom_line(aes(color = V2), size = 1) +
  scale_color_manual(values = c("#D2691E","#00FFFF","#228B22"))   +
  scale_x_continuous(breaks = seq(min(df$V1), max(df$V1))) +
  geom_point(aes(size = V2 == "CNPq"), show.legend = FALSE)  +
  geom_text(aes(label=ifelse(V2 == "CNPq", V3, "")), nudge_y = 1000) +
  scale_size_manual(values=c(-1,1))
