Plotly R sankey plot - 在单个悬停标签上隐藏值

如何解决Plotly R sankey plot - 在单个悬停标签上隐藏值

我在 r (plot_ly) 中使用 plotly 创建了一个非常标准的桑基图。有没有办法在悬停标签中只显示一些值。我想显示所有链接，但由于数据机密性限制，隐藏其中一些链接的特定值。

谢谢

fig <- plot_ly(
  type = "sankey",domain = list(x =  c(0,1),y =  c(0,1)),arrangement = "freeform",orientation = "h",valueformat = ".1f",#valuesuffix = "TWh",key 
  
  node = list(
    label = lab,x=posx,y=posy,color = col,pad = 10,thickness = 15,line = list(color = "black",width = 0.5)
  ),link = list(
    source = sum$source,target = sum$target,value  = sum$value,label  = sum$label,color  = sum$color
  )
) 
fig <- fig %>% layout(
  #title = "",font = list(size = 10),xaxis = list(showgrid = F,zeroline = F),yaxis = list(showgrid = F,zeroline = F)
)
