在facet_grid上强制x轴标签ggplot:x轴标签每行不同 [英] Force x-axis labels on facet_grid ggplot: x-axis labels differ per row
问题描述
我很高兴能在帖子中找到解决我问题的大部分内容,为facet_grid图的所有方面强制X轴文本。
我想创建一个图形,看起来有点像OP Drew Steen's,除了我有两行以上的小平面,并且我想让每行的x轴标签不同。
我从@ baptiste的真棒答案中提出了一个超级黑客解决方案(主要是因为我不熟悉gtable包),我想知道:
- 如果有比我在下面写的乱七八糟的更优雅的解决方案
- (中)行。
这里是我从@Drew Steen和@baptiste改编的代码,
library(ggplot2)
diamondSub< -subset(diamonds,(cut ==Ideal| cu t ==高级| cut ==Very Good)& (color ==E| color ==I))
p < - ggplot(diamondSub,aes(x = carat,y = price))+
geom_blank +
geom_point()+
scale_x_discrete(breaks = c(1,2,3,4),labels = c(a,b,c,d))+
facet_grid(cut〜color,scales =free_x)
p
p2 < - ggplot(diamondSub,aes(x = carat,y = price))+
geom_blank()+
geom_point()+
scale_x_discrete(breaks = c(1,2,3,4),labels = c(f,g,h,i ))+
facet_grid(cut〜color,scales =free_x)
p2
library(gtable)
g< - ggplotGrob p)
g2 < - ggplotGrob(p2)
#找到面板
面板< - grep(panel,g $ layout $ name)
panel2< - grep(panel,g2 $ layout $ name)
top< - unique(g $ layout $ t [panels])
top2< - unique(g2
#散布底层的副本
全部< - gtable ::: rbind_gtable(gtable ::: rbind_gtable(g [seq.int(min(top) ),],
g [max(top)+1,],first),
g2 [seq(min(top2)+1,nrow(g2)),],first)
grid.newpage )
grid.draw(全部)

##替代版本
库(gtable)
库(网格)
#获取ggplot grobs
g< - ggplotGrob(p)
g2< - ggplotGrob(p2)
#显示布局。
#注意行和列
#在这种情况下,g2布局与g布局相同
gtable_show_layout(g)
#大面板是情节板。
#我们需要第4行,第6行和第8行。
#对于顶部的非常好行,我们还需要行1,2和3.
#该轴位于第9行
#因此,在第1行,第2行,第3行和第4行中将grob与第9行中的grob绑定在一起。
top.row< ; - rbind(g [1:4,],g [9,],size =first)
#第二个Premium行
#我们需要行中的面板6加上上面的小间隙行
#并将其与轴
中的行联系起来
middle.row = rbind(g2 [5:6,],g2 [9,],size =first)
#底部理想行
#我们需要第8行的面板加上
#上面的行中的小间隙加上
下面一行中的轴#加上下面的行(轴标签和边距)
bottom.row = g2 [7:11,]
#rbind三行
all< - rbind(rbind(top.row,middle.row,size =first),bottom.row,size =first)
#绘制
grid.newpage()
grid.draw(全部)
#也许在行之间添加更多空间
gtable_show_layou t(全部)
全部$高度[c(6,9)] =单位(1,lines)
#绘制
grid.newpage()
grid.draw(全部)
但是,您甚至不需要执行面板到轴;只需从布局中选择适当的行:
top.row < - g [c(1:4,9), ]
$然后绑定这三个新行。
middle.row = g2 [c(5:6,9),]
bottom.row = g2 [7:11,]
原始版本
只有在行的绑定中,你犯了一个错误。您已将轴绑定到顶部的非常好行。底部的理想行已经有一个轴,所以不需要绑定。修复:中间的Premium行需要一个轴。
我分别构建了每行,将一个轴绑定到顶部和中间行,然后绑定这三行。
我增加了另一步在行之间添加更多空间。
g < - ggplotGrob(p)
g2 < - ggplotGrob(p2)
#找到面板
面板< - grep(panel,g $ layout $ name)
panels2< - grep(panel,g2 $ layout $ name)
top < - unique(g $ layout $ t [panels])
top2< - unique(g2 $ layout $ t [panels2])
#构建每一行分别为
top.row < - gtable ::: rbind_gtable(g [seq.int(min(top)),],g [max(top)+1,],first)
middle.row < - gtable ::: rbind_gtable(g2 [c(top [2] -1,top [2]),],g2 [max(top)+1,],first)
bottom.row < - g2 [(max(top2)-1):nrow(g2),]
全部< - gtable ::: rbind_gtable(gtable ::: rbind_gtable(top.row ,middle.row,first),bottom.row,first)
#绘制
grid.newpage()
grid.draw(全部)
#也许在行之间增加一点空间
all $ heights [c(6,9)] = unit(1,lines)
grid。 newpage()
grid.draw(全部)
I was so happy to find the greater part of a solution to my question in the post, "Force X axis text on for all facets of a facet_grid plot".
I'd like to create a graph to look somewhat like the OP Drew Steen's, except I have more than two rows of facets, and I'd like to make the x-axes labels different for each row.
I made a super-hacky solution out of @baptiste's awesome answer (mostly because I am unfamiliar with the gtable package), and I'd like to know:
- If there is a more elegant solution than the mess I wrote below
- How to insert labels for the "Premium" (middle) row.
Here is the code I adapted from @Drew Steen and @baptiste,
library(ggplot2) diamondSub <-subset(diamonds, (cut=="Ideal" | cut=="Premium" | cut == "Very Good") & (color=="E" | color=="I")) p<- ggplot(diamondSub, aes(x=carat, y=price)) + geom_blank()+ geom_point() + scale_x_discrete(breaks=c(1, 2, 3, 4), labels=c("a", "b", "c", "d")) + facet_grid(cut~color, scales="free_x") p p2<- ggplot(diamondSub, aes(x=carat, y=price)) + geom_blank()+ geom_point() + scale_x_discrete(breaks=c(1, 2, 3, 4), labels=c("f", "g", "h", "i")) + facet_grid(cut~color, scales="free_x") p2 library(gtable) g <- ggplotGrob(p) g2 <- ggplotGrob(p2) # locate the panels panels <- grep("panel", g$layout$name) panels2 <- grep("panel", g2$layout$name) top <- unique(g$layout$t[panels]) top2 <- unique(g2$layout$t[panels2]) # intersperse a copy of the bottom axes all <- gtable:::rbind_gtable(gtable:::rbind_gtable(g[seq.int(min(top)), ], g[max(top)+1,], "first"), g2[seq(min(top2)+1, nrow(g2)),], "first") grid.newpage() grid.draw(all)
解决方案Alternative Version (added 24 April 2015) showing manual construction of the elements and containing more commenting.
## Alternative version library(gtable) library(grid) # Get the ggplot grobs g <- ggplotGrob(p) g2 <- ggplotGrob(p2) # Show the layout. # Note the rows and columns # In this case, the g2 layout is the same as the g layout gtable_show_layout(g) # The large panels are the plot panels. # We will need rows 4, 6 and 8. # For the top "Very Good" row, we will also need rows 1, 2, and 3. # The axis is located in row 9 # Therefore rbind the grob in rows 1, 2, 3, and 4, with the grob in row 9. top.row <- rbind(g[1:4, ], g[9, ], size = "first") # The second "Premium" row # We need the panels in row 6 plus the small gap row above, # and rbind that to the axis middle.row = rbind(g2[5:6, ], g2[9,], size = "first") # The bottom "Ideal" row # We need the panel in row 8 plus the small gap in the row above # plus the axis in the row below # plus rows below that (axis label and margin) bottom.row = g2[7:11, ] # rbind the three rows all <- rbind(rbind(top.row, middle.row, size = "first"), bottom.row, size = "first") # Draw it grid.newpage() grid.draw(all) # Maybe add a little more space between the rows gtable_show_layout(all) all$heights[c(6,9)] = unit(1, "lines") # Draw it grid.newpage() grid.draw(all)
But you don't even need to do the binding of the panel to the axis; just select the appropriate rows from the layout:
top.row <- g[c(1:4, 9), ] middle.row = g2[c(5:6, 9), ] bottom.row = g2[7:11, ]
then bind these three new rows.
Original Version
It is only in the binding of the rows that you have made a mistake. You have bound an axis to the top "Very Good" row. The bottom "Ideal" row already has an axis, so no binding is required. To Fix: The middle "Premium" row needs an axis.
I have constructed each row separately, binding an axis to the top and middle rows, then binding the three rows.
I've added another step to add a little more space between the rows.
g <- ggplotGrob(p) g2 <- ggplotGrob(p2) # locate the panels panels <- grep("panel", g$layout$name) panels2 <- grep("panel", g2$layout$name) top <- unique(g$layout$t[panels]) top2 <- unique(g2$layout$t[panels2]) # Construct each row separately top.row <- gtable:::rbind_gtable(g[seq.int(min(top)), ], g[max(top)+1,], "first") middle.row <- gtable:::rbind_gtable(g2[c(top[2]-1,top[2]), ], g2[max(top)+1,], "first") bottom.row <- g2[(max(top2)-1):nrow(g2), ] all <- gtable:::rbind_gtable(gtable:::rbind_gtable(top.row, middle.row, "first"), bottom.row, "first") # Draw it grid.newpage() grid.draw(all) # Maybe add a little more space between the rows all$heights[c(6,9)] = unit(1, "lines") grid.newpage() grid.draw(all)
