How can I change only the thickness of the color lines in the caption that identify the groups?
I do not send the dput()
graph pq are more than 40 thousand lines. I send a cutout of the figure to identify my problem and send the graph generation code.
I tried a few options on Theme()
but I couldn’t change.
require(ggplot2)
pl <- ggplot(TEPT_CONT_TA_TOC, aes(x = time, y = value, colour = grupo,
group = interaction(grupo, variable))) +
geom_line(alpha = 0.5) + geom_smooth(aes(group = grupo), colour = "black") +
scale_x_continuous(name = "Tempo em segundos",
limits = c(0,300),
breaks = seq(0,300,by = 60)) +
scale_y_continuous(name = expression(paste("(",mu,"S)"))) +
theme(legend.text = element_text(face = "bold",size = 12),
legend.title = element_text(size = 12),
legend.key = element_rect(fill = "white"),
legend.background = element_rect(fill = "white")) +
labs(title = "Resposta Galvânica da Pele",
subtitle = "Behavioral Endocrinology Lab",
colour = "Grupo")
How I make these lines thicker for easier identification of the group?
