here is my data and code for chart line:
df<- data.frame(direct= 10:85, indirect= 55:130, age=15:90)
ggplot(data=df)+
geom_line(mapping=aes(y=direct,x= age,color="direct"),linetype="solid" ) +
geom_line(mapping=aes(y=indirect,x= age,color="indirect"),linetype="dashed") +
scale_color_manual(values = c(
'direct' = 'black',
'indirect' = 'black')) +
labs(color = NULL)+
scale_x_continuous(breaks = seq(15, 90, by = 5))+
labs(y= "Time Spent (in minutes)")+
guides(color = guide_legend(override.aes = list(linetype = c("solid","dashed"))))+
theme_classic()+
theme(plot.title = element_text(hjust = 0.5, size=9, face="bold"),legend.position=c(.90,.90))
I want to put legend in the middle of my each line as the picture:
>Solution :
You can add annotate to your lines. You can use the following code:
library(tidyverse)
df<- data.frame(direct= 10:85, indirect= 55:130, age=15:90)
ggplot(data=df)+
geom_line(mapping=aes(y=direct,x= age,color="direct"),linetype="dashed" ) +
geom_line(mapping=aes(y=indirect,x= age,color="indirect"),linetype="solid") +
scale_color_manual(values = c(
'direct' = 'black',
'indirect' = 'black')) +
labs(color = NULL)+
scale_x_continuous(breaks = seq(15, 90, by = 5))+
labs(y= "Time Spent (in minutes)")+
guides(color = guide_legend(override.aes = list(linetype = c("solid","dashed"))))+
theme_classic()+
theme(plot.title = element_text(hjust = 0.5, size=9, face="bold"), legend.position = "none") +
annotate('text', x=50, y=55, label = "direct")+
annotate('text', x=50, y=100, label = "indirect")
Output:
