R plotly 堆叠条形图文本标签未与条对齐

Question

我花了太长时间在 google/stack overflow 上搜索，试图找到答案，但没有成功！

本质上，我创建了一个堆积条形图，但覆盖的文本标签与正确的条形不对齐。 我试过使用text = ~value ， annotations参数等等......但没有运气。

这是我最新版本的代码和图片示例。 我假设它一定是一个简单的解决方案，但我无法弄清楚！

t <- list(
  size = 12,
  color = 'black')

fig <- df4 %>% plot_ly(x = ~variable, y = ~value, type = 'bar', 
        name = ~Country, color = ~Country) %>%
  layout(yaxis = list(title = '% of Value'), 
         xaxis = list(title = 'Metric'), 
         barmode = 'stack', 
         title = "Proportion of value across countries") %>%
  add_text(text=~value, textposition="middle center",
           showlegend = F, textfont = t)

设法解决它：

fig <- df4 %>% plot_ly(x = ~variable, y = ~value, type = 'bar',
                             text = paste(df4$value,"%"),
                             textposition = "outside",
                             color = ~Country,
                             textfont = t)%>%
  layout(yaxis = list(title = '% of Value'), 
         xaxis = list(title = 'Country'),
         title = "Proportion of value across countries",
         barmode = 'stack') 
fig
