ggplot2中的条形图,宽度作为变量,条间间距甚至相等 [英] Bar graph in ggplot2 with width as a variable and even spacing between bars
问题描述
有谁知道如何使棒之间的间距不变?
现在我得到了这个:
p <-ggplot(dd,aes(variable,value。 )+ coord_flip()+ opts(ylab =)
p1 <-p + geom_bar(stat =identity)+ scale_fill_brewer( palette =Dark2)+ scale_fill_hue(l = 55,c = 55)
p2 <-p1 + opts(axis.title.x = theme_blank(),axis.title.y = theme_blank ))
p2
预先致谢。
这是我的数据顺便说一下(对于长而笨重的dput):

尝试#2。
我试图将ggplot2写成一个连续的范围作为分类。
#手工计算的tmp数字。不知道如何编程
#这部分,但数学是
#last + half(previous_width)+ half(current_width)
#更改cumsum中的第一个数字以调整类别宽度
tmp < - c(2.91,7.02,14.715,27.75,38.22, 46.47,57.845,77.19,101.235)+ cumsum(rep(5,9))
dd $ x.pos1< - rep(tmp,each = 5)
ggplot(dd,aes(x = x.pos1,y = value.y,fill = Date))+
geom_bar(aes (width = value.x),stat =identity,position =stack)+
scale_x_continuous(breaks = tmp,labels = levels(dd $ variable))+
coord_flip()
为了达到最佳效果,您可能需要调整文字大小。这是用 ... + opts(axis.text.y = theme_text(size = 12))
完成的
So I am trying to make a stacked bar graph with bar width mapped to a variable; but I want the spacing between my bars to be constant.
Does anyone know how to make the spacing constant between the bars?
Right now I've got this:
p<-ggplot(dd, aes(variable, value.y, fill=Date, width=value.x / 15))+ coord_flip() + opts(ylab="")
p1<-p+ geom_bar(stat="identity") + scale_fill_brewer(palette="Dark2") + scale_fill_hue(l=55,c=55)
p2<-p1 + opts(axis.title.x = theme_blank(), axis.title.y = theme_blank())
p2
Thanks in advance.
Here's my data by the way (sorry for the long, bulky dput):

20.5)), .Names = c("variable", "value.x", "Date", "value.y"
), row.names = c(NA, -45L), class = "data.frame")
Attempt # 2.
I'm tricking ggplot2 into writing a continuous scale as categorical.
# The numbers for tmp I calculated by hand. Not sure how to program
# this part but the math is
# last + half(previous_width) + half(current_width)
# Change the 1st number in cumsum to adjust the between category width
tmp <- c(2.91,7.02,14.715,27.75,38.22,46.47,57.845,77.19,101.235) + cumsum(rep(5,9))
dd$x.pos1 <- rep(tmp,each=5)
ggplot(dd,aes(x=x.pos1,y=value.y,fill=Date)) +
geom_bar(aes(width=value.x),stat="identity",position="stack") +
scale_x_continuous(breaks=tmp,labels=levels(dd$variable)) +
coord_flip()
For good measure you're probably going to want to adjust the text size. That's done with ... + opts(axis.text.y=theme_text(size=12))
