这是我正在使用的数据:
Habitat x y
Bukit Durang -0.318 -0.214
Bukit Durang 0.226 -0.450
Bukit Durang -0.074 -0.412
HCV4 0.062 -0.140
HCV4 -0.007 0.465
HCV4 -0.096 -0.049
Oil Palm 1 -0.281 0.058
Oil Palm 1 -0.051 0.189
Oil Palm 1 -0.058 0.188
Oil Palm 2 0.415 0.024
Oil Palm 2 0.137 0.136
Oil Palm 2 0.564 0.205
我用它来生成带代码的图表:
ggplot(MDS.Hym.Data, aes(x=x,y=y,shape = Habitat))+
geom_point()+
ylab("MDS Axis2")+
xlab("MDS Axis1")+
scale_y_continuous(limits = c(-0.5,0.5), breaks=c(-0.4,-0.2,0,0.2,0.4))+
scale_x_continuous(limits = c(-0.6,0.6), breaks=c(-0.6,-0.3,0,0.3,0.6))+
scale_shape_manual(values = c(15,17,4,1))+
theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(),
panel.background = element_blank(), axis.line = element_line(colour = "black"),
axis.text.x = element_text(colour = "black"),
axis.text.y = element_text(colour= "black"),
legend.position = "none")
然而,这个图表连接了x和y轴。我想分开,因为两个轴都不是从0开始。
有人可以告诉我如何做到这一点吗?
