在 plotly 仪表图中添加悬停文本或文本注释

如何解决在 plotly 仪表图中添加悬停文本或文本注释

我们可以在 plotly 仪表图表中添加悬停文本或文本注释吗？例如，在我下面的图中，我想在绿色区域中添加悬停或文本或同时添加 "Uptake first dose%: 19.8" 和灰色区域 "Not vaccinated (%):80.2"

library(plotly)

fig <- plot_ly(
  type = "indicator",mode = "gauge+number+delta",value = 19.8,title = list(text = "Uptake first dose %",font = list(size = 24)),delta = list(reference = 70,increasing = list(color = "gray")),gauge = list(
    axis = list(range = list(NULL,100),tickwidth = 1,tickcolor = "lightgreen"),bar = list(color = "lightgreen"),bgcolor = "white",borderwidth = 2,bordercolor = "gray",steps = list(
      list(range = c(0,50),color = "lightgreen"),list(range = c(20,color = "gray")),threshold = list(
      line = list(color = "black",width = 4),thickness = 0.75,value = 70))) 
fig <- fig %>%
  layout(
    margin = list(l=20,r=30),paper_bgcolor = "lavender",font = list(color = "darkblue",family = "Arial"))

fig
