删除显示在绘图条形图的悬停信息框中的名称（跟踪）

Question

我有下面的数据框：

并创建了下面的堆积条形图。悬停文本的问题是 name 显示为开箱即用，应将其从那里删除。

fig <- plot_ly(x = ~`Element Name`,text=~Department,
               
data = dp) %>% 
  add_bars(y = ~`DemandCourse`, name = "Demand",
           hovertemplate = "Chemical Name: %{x}<br>Demand: %{y}<br>Department: %{text}") %>% 
  add_bars(y = ~`Amount Available`, name = "Amount Available",
           hovertemplate = "Chemical Name: %{x}<br>Available Amount: %{y}<br>Department: %{text}") %>% 
  
  layout(showLegend = T, barmode = "stack",
         xaxis = list(title = "Element Name",tickangle=45),
         yaxis = list(title = "Amount Available"),
         title="Amount and Demand per Element")
fig

Answer 1

将 添加到 hovertemplate 字段中字符串的末尾。例如，hovertemplate =“化学名称：%{x}
可用数量：%{y}
部门：%{text}”
