r - 使用 R plotly 中的标记将抖动添加到分组箱线图

Question

我想要 互动 (这意味着可以使用框/套索选择来选择它们)抖动点显示在 分组箱线图 .我是从这个问题出来的:Add jitter to box plot using markers in plotly .我想要完全相同，但箱线图应该分组。

我做了一个箱线图，但点都混淆了:

dat %>%
  plot_ly(x = ~as.numeric(IC), 
            y = ~xval, 
            color = ~gene, 
            type = "box",
            hoverinfo = "none",
            boxpoints = FALSE
          ) %>%
  add_markers(x = ~jitter(as.numeric(IC)),
              y = ~xval,
              color = ~gene,
              marker = list(size = 3),
              hoverinfo = "text",
              text = txt,
              showlegend = TRUE) %>%
layout(boxmode = "group")

当我尝试将 X 轴按因子分组(这样每个组合都是一个级别)时，我无法将我的箱线图分组:

dat <- dat %>% 
  mutate(gene_x_covariate = as.factor(
    paste0(get(facet_title), "-", gene))) 

dat %>%
  plot_ly(x = ~as.numeric(gene_x_covariate), 
            y = ~xval, 
            color = ~gene, 
            type = "box",
            hoverinfo = "none",
            boxpoints = FALSE
          ) %>%
  add_markers(x = ~jitter(as.numeric(gene_x_covariate)),
              y = ~xval,
              color = ~gene,
              marker = list(size = 3),
              hoverinfo = "text",
              text = txt,
              showlegend = TRUE) %>%
layout(boxmode = "group")

当我尝试在 X 轴上混合变量时，我从箱线图中得到了点:

dat %>%
  plot_ly(x = ~as.numeric(IC), 
            y = ~xval, 
            color = ~gene, 
            type = "box",
            hoverinfo = "none"
          ) %>%
  add_markers(x = ~jitter(as.numeric(gene_x_covariate)),
              y = ~xval,
              color = ~gene,
              marker = list(size = 3),
              hoverinfo = "text",
              text = txt,
              showlegend = TRUE) %>%
layout(boxmode = "group")

有任何想法吗？

Answer 1

boxpoints 对你有用吗？ See this
您可以通过 pointpos 参数移动这些点。

iris %>% 
  plot_ly(x = ~cut( Sepal.Length, breaks = 4), 
          y = ~Petal.Width, 
          color = ~Species, 
          type = "box",
          marker = list( size = 10),
          boxpoints = "all",
          jitter = 0.4,
          pointpos = 0,
          hoverinfo = "all"
  ) %>% layout( boxmode = "group")
