每个人 -

我在增加我的 circlize 图的内部向量的高度时遇到了一些麻烦。我希望它足够大以包含放大的标签（见图）。我主要是在这个职位上工作。我还有一个问题，为什么与 htat 使用R 中的循环可视化中chordDiagram()的示例生成图的许多博客文章相比，为什么我的图看起来非常像素化。我在尝试为链接添加边框时遇到问题。任何其他格式提示将不胜感激。感谢您的时间和建议。

尝试在 circos.par() 中定义 track.height。

编辑

只需更改annotationTrackHeight = c(0.03, 0.01)为即可annotationTrackHeight = 0.08。

ccircos.par(start.degree = 135,
           track.margin = c(.01,0.01))

chordDiagram(df[,1:3], 
             order = c("BM","LSM", "SJC","SCM","ZM","MT","SMM","SM","TP","CHC","HSRM","SIN","GC","MR"),
             grid.col = correlated_color,
             #link.border = border.color,
             #annotationTrackHeight = c(0.03, 0.01),
             annotationTrackHeight = 0.08,
             link.arr.type = "big.arrow",
             link.arr.length = uh(3, "mm"),
             link.rank = rank(df$value),
             h.ratio = 0.8,
             transparency = .5,
             directional = 1,
             diffHeight = -uh(1, "mm"),
             direction.type = c("diffHeight", "arrows"),
             annotationTrack = c("grid"),
             preAllocateTracks = list(
               list(track.height = 0.03)))

circos.trackPlotRegion(track.index = 2, 
                       panel.fun = function(x, y) {
                         xlim = get.cell.meta.data("xlim")
                         ylim = get.cell.meta.data("ylim")
                         sector.index = get.cell.meta.data("sector.index")
                         circos.text(mean(xlim), 
                                     mean(ylim), 
                                     sector.index, 
                                     col = "white",
                                     cex = 0.8,
                                     facing = "bending.inside", 
                                     niceFacing = TRUE)
                       }, bg.border = NA)

for(p in unique(pop_id)) {
  sub_pop = names(pop_id[pop_id == p])
  highlight.sector(sector.index = sub_pop, 
                   track.index = 1, 
                   col = uncorrelated_color[p], 
                   text = p,
