制作一条ggplot线条图,其中线条遵循行顺序 [英] Make a ggplot line plot where lines follow row order
问题描述
我正在制作一个ggplot线图,或者最好将它描述为一个散点图,并用指定方式连接这些点。这是我的示例数据:
X <-c(-37,-25,-27,4,20,30, 22,10)
Y <-c(-5,-9,10,15,-13,-0.04,4,0.03)
Day <-c(1,2,3,4, 5,6,7,8)
DF <-data.frame(X,Y,Day)
目标是绘制XY点,并且按时间顺序连接点(第1天连接到第2天,第2天到第3天等)。如果我的情节如此:
ggplot(DF,aes(x = X,y = Y,label = Day) = fALSE)+
geom_line(,size = 0.3)+
geom_point(fill ='red',shape = 21)+
geom_text(size = 7)+
theme_bw )
使用您的数据 使用您的数据,
ggplot(DF,aes(x = X,y = Y))+ geom_point()+ geom_path()
产生这个,这听起来像你在问什么(??)
I'm making a ggplot line plot, or perhaps it would be better to describe it as a scatter plot with lines connecting the points in a specified manner. Here is my example data:
X<-c(-37,-25,-27,4,20,30,22,10)
Y<-c(-5,-9,10,15,-13,-0.04,4,0.03)
Day<-c(1,2,3,4,5,6,7,8)
DF<-data.frame(X,Y,Day)
The goal is to plot out the X Y points, and have lines connecting the points chronologically (Day 1 connected to Day 2, Day 2 to Day 3, ect). If I plot like so:
ggplot(DF,aes(x=X, y=Y, label=Day),legend=FALSE)+
geom_line(,size=0.3)+
geom_point( fill='red', shape=21)+
geom_text(size=7)+
theme_bw()
But as can be seen the points are connected increasingly up the X axis (Day 1 is connected to Day 3, Day 3 to Day 2, ect). Is there a way to change the default of the ggplot line plot to follow the pattern as laid out in the "Day" column? Or alternatively, to follow the ordering of rows in DF (both of which should yield the same results)?
Using your data,
ggplot(DF, aes(x=X,y=Y))+geom_point()+geom_path()
Produces this, which sounds like what you are asking(??)
