我的问题与类似,但我无法使该答案适用于我的情节。

我正在geom_linerange为一组名称 ( 1:20) 制作时间线,每个名称都与赞助商 ( B:E) 相关联。我想“刻面”图表,以便名称/时间线按赞助商分组。到目前为止,如果我创建一个包含赞助商+名称的“组合”因子,我可以获得一个组合图。但是,如果我尝试分面,那么每个赞助商都会得到所有的名字。

这是我的数据集(我lubridate用于日期...)的(修改后的子集):

structure(list(Sponsor = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 
1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L), .Label = c("B", 
"C", "D", "E"), class = "factor"), Last = structure(1:20, .Label = c("1", 
"2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", 
"14", "15", "16", "17", "18", "19", "20"), class = "factor"), 
Grant = c(0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0.5, 
0, 1, 1, 0), Start = structure(c(844128000, 904003200, 1001289600, 
1314835200, 1064188800, 1107561600, 1138838400, 1264896000, 
1222819200, 1042502400, 1343779200, 904521600, 950832000, 
1009929600, 1081209600, 1171929600, 821664000, 865209600, 
979603200, 1209600000), class = c("POSIXct", "POSIXt"), tzone = "UTC"), 
End = structure(c(929232000, 946684800, 1088035200, NA, 1109721600, 
1324512000, 1232496000, NA, NA, 1101859200, 1388448000, 993859200, 
1006819200, 1103500800, 1139529600, 1235952000, 919036800, 
1030665600, 1047254400, 1272585600), class = c("POSIXct", 
"POSIXt"), tzone = "UTC"), Combo = c("B_1", "B_2", "B_3", 
"B_4", "B_5", "B_6", "B_7", "B_8", "C_9", "C_10", "C_11", 
"D_12", "D_13", "D_14", "D_15", "D_16", "E_17", "E_18", "E_19", 
"E_20")), .Names = c("Sponsor", "Last", "Grant", "Start", 
"End", "Combo"), row.names = c(NA, 20L), class = "data.frame")

这是生成按顺序分组但不细分的非分面图的命令:

library(ggplot2)
require(lubridate)

YearLine = ymd(19960101) + years(seq(0,18))

ggplot(testdat,aes(Combo, Start, ymin=Start,ymax=End,color=as.factor(Grant),xticks)) + xlab("Sponsor") + geom_linerange(size=4,alpha=.7) + geom_point(size=4,shape=18) + coord_flip()  + scale_colour_brewer(palette="Spectral") + scale_x_discrete(labels=testdat$Sponsor) + geom_hline(yintercept = as.numeric(YearLine),alpha=0.6,col="indianred1",linetype="dotted")  + annotate("text", x = testdat$Combo, y = testdat$Start, label = testdat$Last, hjust=0,size=2.5)

这是由此产生的情节。这是我想要的(因为它不是多余的),但我希望它由赞助商细分:

绘图示例

如果我添加+ facet_grid(Sponsor ~ .,scale="free_x",space="free_x")(或free_y),那么它会像我希望的那样对赞助商的面板进行分面,但我仍然会列出所有名称,即使它们与“赞助商”B 到 E 无关:

您遇到的主要问题是annotate在需要使用的地方使用geom_text

ggplot(testdat,aes(Combo, Start, ymin=Start,ymax=End,color=as.factor(Grant),xticks)) + 
  xlab("Sponsor") + geom_linerange(size=4,alpha=.7) + geom_point(size=4,shape=18) + coord_flip()  + 
  scale_colour_brewer(palette="Spectral") + 
  scale_x_discrete(labels=testdat$Sponsor) + 
  geom_hline(yintercept = as.numeric(YearLine),alpha=0.6,col="indianred1",linetype="dotted")  + 
  geom_text(aes(x=Combo, y=Start, label = testdat$Last), colour="black") +
  facet_grid(Sponsor ~ .,scale="free_x",space="free_x")

annotate并没有真正遵循您为情节的其余部分定义的现有美学映射,这就是它不受您的刻面影响的原因。
