我制作的极地情节如下:
library(ggplot2)
ggplot(data, aes(x = legend.var, y = score, fill = Indicator), color='black') +
geom_bar(width = 1, alpha=0.5, stat="identity") +
scale_y_continuous() +
coord_polar() +
theme( axis.ticks = element_blank()) +
facet_wrap(~Village, nrow=2, ncol=3) +
guides(colour = guide_legend(title.hjust = 0.5))
正如您在数据中看到的那样,列legend.var
按列indicator
分组。我想插入一个表格或第二个图例,将每个指标与legend.var
和variables
列相关联。理想情况下,如果将其作为第二个图例插入,legend.var
列中包含的唯一项目将具有与相应指标相同的填充颜色。填充图例基于列indicator
。插入的表/额外图例将包含具有唯一字母表的列legend.var
和具有相应字母表含义的列variables
。然后,这些颜色可以与相应的indicator
具有相同的填充颜色。我希望这很清楚。

首先,您可以尝试这样的事情。您需要根据自己的喜好调整排列和布局。
library(ggplot2)
library(gridExtra)
gg <- ggplot(data, aes(x = legend.var, y = score, fill = Indicator), color='black') +
geom_bar(width = 1, alpha=0.5, stat="identity") +
coord_polar() +
theme(axis.ticks = element_blank()) +
facet_wrap(~Village, nrow=2, ncol = 3)
# create a table that translates legend.var to Variables
tbl <- unique(data[ , c("legend.var", "Variables")])
# create a table grob
tt <- tableGrob(d = tbl,
col.just = "left",
gpar.coretext = gpar(col = "black", cex = 0.5),
gpar.coltext = gpar(col = "black", cex = 0.5, fontface = "bold"),
gpar.rowtext = gpar(col = "black", cex = 0.5, fontface = "italic"))
# arrange plot and table grob
grid.arrange(gg, tt, ncol = 2)
使用快速且脏的ggplot替代
进行更新# create labels
labs <- with(tbl, paste(legend.var, Variables))
gg <- ggplot(data, aes(x = legend.var, y = score, fill = Indicator, col = Variables)) +
geom_bar(width = 1, alpha = 0.5, stat = "identity") +
coord_polar() +
theme(axis.ticks = element_blank()) +
facet_wrap(~ Village, nrow = 2, ncol = 3) +
scale_color_grey(labels = labs, start = 0.8, end = 0.9)
gg

以下是使用gtable
:
library(ggplot2)
p <- ggplot(data, aes(x = legend.var, y = score, fill = Indicator), color='black') +
geom_bar(width = 1, alpha=0.5, stat="identity") +
scale_y_continuous() +
coord_polar() +
theme( axis.ticks = element_blank()) +
facet_wrap(~Village, nrow=2, ncol=3) +
guides(colour = guide_legend(title.hjust = 0.5)) +
theme(legend.position=c(0.85,0.25))
#create table
library(gridExtra)
tab <- tableGrob(unique(data[, c("legend.var", "Variables")]),
show.rownames=FALSE, gpar.coretext=gpar(fontsize=10),
gpar.coltext=gpar(fontsize=10, fontface='bold'),
gpar.corefill = gpar(fill = "grey90", col = "white"),
gpar.colfill = gpar(fill = "grey80", col = "white"))
#arrange grobs
library(gtable)
a <- gtable(unit(c(0.7, 0.3) ,c("npc")), unit(1, "npc"))
a <- gtable_add_grob(a, ggplotGrob(p),1,1)
a <- gtable_add_grob(a, tab,1,2)
#plot
grid.draw(a)
