在图中使用标记将抖动添加到框图中

Question

我制作了一个箱形图：

dat %>%
  plot_ly(y = ~xval, color = ~get(col), type = "box", 
          boxpoints = "all", jitter = 0.7,
          pointpos = 0, marker = list(size = 3),
          source = shiny_source, key = shiny_key,
          hoverinfo = 'text', text = txt)

但问题是抖动的点不是交互式的，不能单独标记，所以我想到了使用add_markers添加这些点的想法：

dat %>%
  plot_ly(y = ~xval, color = ~get(col), type = "box", 
          boxpoints = FALSE, jitter = 0.7,
          pointpos = 0, marker = list(size = 3),
          source = shiny_source, key = shiny_key,
          hoverinfo = 'col', text = txt
  ) %>%
  add_markers(x = ~get(col), y = ~varval, size = I(6))

但现在点是直线的，我想添加一些抖动（例如使用beeswarm包）。 但我不知道如何在X轴上获得定性变量IC0坐标。 有任何想法吗？

我发现自己在同潜在情况往往与plotly和ggplot2-- 3行代码来获得我想要的90％，和30行代码来获得美感恰到好处 。

一个潜在的解决方案/解决方法：利用R的“因子用整数编码”范例，在数字刻度上绘制所有内容，然后通过隐藏x标签和x悬停值来覆盖轨道。

dat <- data.frame(xval = sample(100,1000,replace = TRUE),
                  group = as.factor(sample(c("a","b","c"),1000,replace = TRUE)))

dat %>%
  plot_ly() %>% 
  add_trace(x = ~as.numeric(group),y = ~xval, color = ~group, type = "box", 
            hoverinfo = 'name+y') %>%
  add_markers(x = ~jitter(as.numeric(group)), y = ~xval, color = ~group,
              marker = list(size = 6),
              hoverinfo = "text",
              text = ~paste0("Group: ",group,
                             "<br>xval: ",xval),
              showlegend = FALSE) %>% 
  layout(legend = list(orientation = "h",
                       x =0.5, xanchor = "center",
                       y = 1, yanchor = "bottom"
                       ),
         xaxis = list(title = "Group",
                      showticklabels = FALSE))
