添加饼图图例 由于geom_polygon&geom_scatterpie都会产生图例,无法只选择一个;因此全部设置show.legend = F;最后通过Legend( )重新绘制图例 lgd=Legend(labels=c("B","C","D"),legend_gp=gpar(fill=c("#FED439FF","#709AE1FF","#197EC0FF")),grid_width=unit(7,"mm"),grid_height=unit(7,"mm")...

Another way to change the legend title and labels is to directly modify the data frame. pg <- PlantGrowth # Copy data into new data frame # Rename the column and the values in the factor levels(pg$group)[levels(pg$group)=="ctrl"] <- "Control" levels(pg$group)[levels(pg$group)==...
theme(legend.position="top") 文本注释 对图形进行文本注释有以下方法: geom_text: 文本注释 geom_label: 文本注释,类似于geom_text,只是多了个背景框 annotate: 文本注释 annotation_custom: 分面时可以在所有的面板进行文本注释 set.seed(1234) df <- mtcars[sample(1:nrow(mtcars), 10), ] df$cyl...
bp + theme(legend.position="none") 1. 2. 修改图例的内容 改变图例的顺序为 trt1, ctrl, trt2: bp + scale_fill_discrete(breaks=c("trt1","ctrl","trt2")) 1. 根据不同的分类,可以使用scale_fill_manual,scale_colour_hue,scale_colour_manual,scale_shape_discrete,scale_linetype_discrete ...

The code for the plot also has to be modified to create more room for the legend. In addition, even though I've turned off clipping for all grobs, the labels are still clipped by the legend grob. You can position the labels outside of the clipped area, but then they're too far ...
