如何在 R ggplot2 中显示 X 和 Y 轴上的所有值

cycle_time <- 1:15
volume <- c(109.12,381.11,812.31,1109,4439.32, 12148.29,32514.32,82231.24,183348.44,329472.36,462381.96,541111.67,
            576516.09, 590450.40,595642.83)

dfx <- data.frame(cycle_time,volume)

p1<- ggplot(dfx, aes(cycle_time,volume)) + geom_line()
p1 +
  scale_x_continuous(breaks=seq(1,15,1))+
  scale_y_continuous(labels=scales::comma)
