我正在制作一个Ramachandran情节,我想在两点之间划一条线。我正在使用此代码:
size lines name
156K 708 sash
16K 64 hostname
120K 460 netstat
40K 110 fuser
644K 1555 dir/bash
28K 82 keyctl
2.3M 8067 vim
我有这个:
但是我想把另外两条水平线放在这个图上:
我使用了hline,但不知道如何在两点之间定义它。
答案 0 :(得分:2)
使用geom_segment
df <- data.frame(x1 = 0, x2 = -180, y1 = 0, y2 = 0) #Data frame with the points
ggplot(result) +
scale_x_continuous(limits = c(-180,180), breaks = seq(-180,180,40), expand=c(0,0)) +
scale_y_continuous(limits = c(-180,180), breaks = seq(-180,180,40), expand=c(0,0)) +
geom_hex(aes(x, y), bins = 500) +
geom_vline(xintercept = 0, colour="red", linetype = "longdash") +
geom_segment(aes(x = x1, y = y1, xend = x2, yend = y2, colour = "segment"), data = df)+
scale_fill_gradientn("", colours = rev(rainbow(10, end = 4/6))) + ylab(expression(paste(psi))) + xlab(expression(paste(phi)))
