本文介绍了在facet_grid上强制x轴标签ggplot:x轴标签每行不同的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 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 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 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 #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g [max(top)+1,],first), g2 [seq(min(top2)+1,nrow(g2)),],first) grid.newpage ) grid.draw(全部) 解决方案 strong>(2015年4月24日添加),显示元素的手动构建并包含更多评论。 ##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 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 g2 #找到面板面板< - grep(panel,g $ layout $ name) panels2< - grep(panel,g2 $ layout $ name) top top2< - unique(g2 $ layout $ t [panels2]) #构建每一行分别为 top.row middle.row bottom.row 全部 #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 belowHow 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")pp2<- 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")p2library(gtable)g <- ggplotGrob(p)g2 <- ggplotGrob(p2)# locate the panelspanels <- 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 axesall <- 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 versionlibrary(gtable)library(grid)# Get the ggplot grobsg <- 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 layoutgtable_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 axismiddle.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 rowsall <- rbind(rbind(top.row, middle.row, size = "first"), bottom.row, size = "first")# Draw itgrid.newpage()grid.draw(all)# Maybe add a little more space between the rowsgtable_show_layout(all)all$heights[c(6,9)] = unit(1, "lines")# Draw itgrid.newpage()grid.draw(all)But you don't even need to do the binding of the panel to the axis; just select the appropriate rows from the layout:top.row <- g[c(1:4, 9), ]middle.row = g2[c(5:6, 9), ]bottom.row = g2[7:11, ]then bind these three new rows.Original VersionIt is only in the binding of the rows that you have made a mistake. You have bound an axis to the top "Very Good" row. The bottom "Ideal" row already has an axis, so no binding is required. To Fix: The middle "Premium" row needs an axis.I have constructed each row separately, binding an axis to the top and middle rows, then binding the three rows.I've added another step to add a little more space between the rows. g <- ggplotGrob(p)g2 <- ggplotGrob(p2)# locate the panelspanels <- grep("panel", g$layout$name)panels2 <- grep("panel", g2$layout$name)top <- unique(g$layout$t[panels])top2 <- unique(g2$layout$t[panels2])# Construct each row separatelytop.row <- gtable:::rbind_gtable(g[seq.int(min(top)), ], g[max(top)+1,], "first")middle.row <- gtable:::rbind_gtable(g2[c(top[2]-1,top[2]), ], g2[max(top)+1,], "first")bottom.row <- g2[(max(top2)-1):nrow(g2), ]all <- gtable:::rbind_gtable(gtable:::rbind_gtable(top.row, middle.row, "first"), bottom.row, "first")# Draw itgrid.newpage()grid.draw(all)# Maybe add a little more space between the rowsall$heights[c(6,9)] = unit(1, "lines")grid.newpage()grid.draw(all) 这篇关于在facet_grid上强制x轴标签ggplot:x轴标签每行不同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! 上岸,阿里云! 07-31 02:31
