问题描述
我参考,并有其他问题。
我修改代码如下:
pre > library(ggplot2)
id< - letters [1:2]
用于填充颜色的ID和值
值< - data.frame(
id = ids,
value = c(4,5)
)
#多边形位置
位置< ; - data.frame(
id = c(rep(ids,each = 10),rep(b,5)),
#shape hole shape hole
x = c(1 ,4,4,1,1,2,2,3,3,2,5,10,10,5,5,6,6,7,7,6,8,8,9,9,8),
y = c(1,1,4,4,1,2,3,3,2,2,5,5,10,10,5,6,7,7,6,6,8,9 ,9,8,8)
)
#合并位置和值
datapoly< - merge(values,positions,by = c(id))
图< - ggplot(datapoly,aes(x = x,y = y))+
geom_polygon(aes(group = id,fill = factor(value)),color =grey )+
scale_fill _discrete(Key)
并给出以下输出:
有一条线穿过两个彩色框,我不太喜欢它,我怎么去除它?谢谢。
试试这个
ggplot(datapoly,aes(x = x,y = y))+
geom_polygon(aes(group = id,fill = factor(value))+
scale_fill_discrete(Key )
I refer to the answer for this question and have additional question.
I have modify the code as below:
library(ggplot2)
ids <- letters[1:2]
# IDs and values to use for fill colour
values <- data.frame(
id = ids,
value = c(4,5)
)
# Polygon position
positions <- data.frame(
id = c(rep(ids, each = 10),rep("b",5)),
# shape hole shape hole
x = c(1,4,4,1,1, 2,2,3,3,2, 5,10,10,5,5, 6,6,7,7,6, 8,8,9,9,8),
y = c(1,1,4,4,1, 2,3,3,2,2, 5,5,10,10,5, 6,7,7,6,6, 8,9,9,8,8)
)
# Merge positions and values
datapoly <- merge(values, positions, by=c("id"))
chart <- ggplot(datapoly, aes(x=x, y=y)) +
geom_polygon(aes(group=id, fill=factor(value)),colour="grey") +
scale_fill_discrete("Key")
And gives the following output:
There is a line passing through the two colored boxes, which I don't quite like it, how can I remove that? Thanks.
Try this one
ggplot(datapoly, aes(x=x, y=y)) +
geom_polygon(aes(group=id, fill=factor(value))) +
scale_fill_discrete("Key")
这篇关于带多个孔的geom_polygon的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
