我问这个没有找到尝试的东西,因为我没有找到相同的东西。我为此道歉。
来自this条形图:
df <- structure(list(year = 2002:2005, work = c(1L, 2L, 3L, 2L), confid = c(8L,
5L, 0L, 6L), jrs = c(0L, 3L, 4L, 5L)), .Names = c("year", "work",
"confid", "jrs"), class = "data.frame", row.names = c(NA, -4L
))
library(ggplot2)
library(reshape)
md <- melt(df, id=(c("year")))
temp.plot <- ggplot(data=md, aes(x=year, y=value, fill=variable) ) +
geom_bar(stat="identity")+
theme(axis.text.x=element_text(angle=90))+
ggtitle("Score Distribtion")
temp.plot
我想问一下,是否有任何简单的方法使用ggplot2来获得每年的值,因为它在每个变量的barplot中。 这里有一个虚拟示例输出:
答案 0 :(得分:10)
在每个条形图中绘制计数可能更好。例如:
tableGrob
如果您仍然想要一个表格下方的表格,我不知道一个简单的方法,但您可以为表格创建一个单独的library(grid)
library(gridExtra)
# Function to extract legend
# https://stackoverflow.com/a/13650878/496488
g_legend <- function(a.gplot){
tmp <- ggplot_gtable(ggplot_build(a.gplot))
leg <- which(sapply(tmp$grobs, function(x) x$name) == "guide-box")
legend <- tmp$grobs[[leg]]
return(legend)}
p = ggplot(data=md, aes(x=year, y=value, fill=variable) ) +
geom_bar(stat="identity")+
#theme(axis.text.x=element_text(angle=90, vjust=0.5, hjust=0.5))+
ggtitle("Score Distribution") +
labs(fill="")
# Extract the legend as a separate grob
leg = g_legend(p)
# Create a table grob
tab = t(df)
tab = tableGrob(tab, rows=NULL)
tab$widths <- unit(rep(1/ncol(tab), ncol(tab)), "npc")
# Lay out plot, legend, and table grob
grid.arrange(arrangeGrob(nullGrob(),
p + guides(fill=FALSE) +
theme(axis.text.x=element_blank(),
axis.title.x=element_blank(),
axis.ticks.x=element_blank()),
widths=c(1,8)),
arrangeGrob(arrangeGrob(nullGrob(),leg,heights=c(1,10)),
tab, nullGrob(), widths=c(6,20,1)),
heights=c(4,1))
,将图例作为单独的grob(图形对象)提取,然后分别布置每个部分。布置各个部分需要手动调整,虽然比我更了解网格图形的人可能能够自动化。这是一个例子:
import re
special_chars = ["?", "[", "]", "/", "\\", "=", "<", ">", ":", ";", ",", "'", "\"", "&", "$", "#", "*", "(", ")", "|", "~", "`", "!", "{", "}", "%", "+"]
uri = "photo's url.jpeg"
#use str.replace
for i in special_chars:
uri = uri.replace(i, "")
#or re.sub
#uri = re.sub("\?|\[|\]|/|\\|\=|<|>|:|;|,|'|\"|\&|\$|#|\*|\(|\)|~|`|!|\{|\}|%|\+", "", uri)
uri = re.sub("\s+", "-", uri)
print(uri)
