Javascript 如何在不重新渲染的情况下更新R Shining中plotly小部件的显示/隐藏跟踪以响应actionbuttons

Javascript 如何在不重新渲染的情况下更新R Shining中plotly小部件的显示/隐藏跟踪以响应actionbuttons,javascript,r,shiny,plotly,r-plotly,Javascript,R,Shiny,Plotly,R Plotly,我正在寻找一种方法,将操作按钮点击链接到图例状态true/legendoly,它不会导致绘图对象的重新呈现,而是改变小部件。当前底部的演示应用程序确实实现了链接,但它是通过完全重新绘制绘图来实现的 我的目标是将指示保留/删除群集的按钮链接到图形中双向数据的可视化,以更新图形,而不是渲染图形。我当前的解决方案确实会导致完全渲染 交互作用是,即按钮更改图例/绘图&图例更改按钮 我添加了一些图片来解释工作流程 我在更大的实际应用程序中为更大的绘图构建了一个测试版本,其中用户有以下视图: 在这里,用户

我的目标是将指示保留/删除群集的按钮链接到图形中双向数据的可视化,以更新图形,而不是渲染图形。我当前的解决方案确实会导致完全渲染

交互作用是,即按钮更改图例/绘图&图例更改按钮

我添加了一些图片来解释工作流程

我在更大的实际应用程序中为更大的绘图构建了一个测试版本,其中用户有以下视图:

在这里,用户可以通过in/out按钮选择要删除哪些集群以进行进一步处理

由于前面的问题,我现在有了一个测试应用程序,其中: -1单击图例会更改绘图和左侧的按钮状态,因此用户可以使用绘图进行输入/输出选择 -2每当绘图重新渲染时,它现在也会重新激活每个轨迹的上一个显示/隐藏状态

第1点是工作流程: 第二点是在
onRender

  if(values$colors) { for(i in seq_along(p1$x$data)){
  p1$x$data[[i]]$visible <- values$legenditems[[p1$x$data[[i]]$name]]}
}
 p1 %>% onRender(js, data = "tracesPlot1")
if(值$colors){for(i在seq_中沿(p1$x$data)){
p1$x$data[[i]]$visible%onRender(js,data=“tracesPlot1”)
目前还有第三种交互,当用户单击按钮时,会导致跟踪隐藏。这种方法就是这里的问题。它目前遵循下图中的橙色流程,但我希望通过javascript解决方案来改变这一点,避免重新渲染绘图:

js你能试试这个吗:

library(plotly)
library(shiny)
library(htmlwidgets)

js <- c(
  "function(el, x){",
  "  var data = el.data;",
  "  $('#btn').on('click', function() {",
  "    var traceName = $('#selector').val();",
  "    $.each(data, function(index,value){",
  "      if(value.name == traceName){",
  "        var v0 = data[index].visible || true;",
  "        var v = v0 == true ? 'legendonly' : true;",
  "        Plotly.restyle(el, {visible: v}, [index]);",
  "      }",
  "    });",
  "  });",
  "}")

ui <- fluidPage(
  plotlyOutput("plot"),
  selectInput("selector", "", choices = c("drat", "wt", "qsec")),
  actionButton("btn", "Show/hide")
)

server <- function(input, output, session) {

  output$plot <- renderPlotly({
    p <- plot_ly()
    for(name in c("drat", "wt", "qsec"))
    {
      p = add_markers(p, x = as.numeric(mtcars$cyl), y = as.numeric(mtcars[[name]]), name = name)
    }
    p %>% onRender(js)
  })

}

shinyApp(ui, server)
并且不使用
onRender

但这仅适用于一个绘图。如果要将按钮链接到多个绘图,假设按钮id具有表单
btn-plot2-5
,则执行以下操作:

js <- c(
  "function toggleLegend(id){",
  "  var ids = id.split('-');",
  "  var plotid = ids[1];",
  "  var index = parseInt(ids[2])-1;",
  "  var plot = document.getElementById(plotid);",
  "  var data = plot.data;",
  "  var v0 = data[index].visible || true;",
  "  var v = v0 == true ? 'legendonly' : true;",
  "  Plotly.restyle(plot, {visible: v}, [index]);",
  "}")

js你确定这是可能的吗?据我所知,shiny一直在重新渲染东西(按需).是的,在前面的问题中,我们使用javascript更改绘图的单个数据点,或者重新设置现有对象的轴的样式,还有更多关于通过JavaScripty对绘图进行更改的内容。是的,这就是我所想的。mmm确实有效,但与听带有ID的按钮列表完全不同,也许这很容易呃,如果我给你发邮件让我们讨论一下的话?嘿,Stephane,我正要回答你,有特定于情节的编辑很好,多个按钮的方向是正确的,但我的情况是一个按钮代表一个轨迹(与您的示例中的绘图版本不同。如果您查看我的虚拟应用程序,右侧的3个按钮代表跟踪1、2、3。stripsplit的技巧应该是完美的。我将对其进行一些编辑,我猜,因为我的按钮从1-n运行,我从0-nok知道跟踪,我添加了以下内容:“var trace=index-1,并在测试应用程序中使用javascript中的向下跟踪替换索引,但我发现我的测试应用程序中无法使用它,因为在循环中使用添加标记进行绘图的方法非常不同。有没有一种方法可以简单地链接javascript以按数字而不是按名称切换跟踪?那样的方法无论(在我的真实应用程序中)记录道是1,2,3etc还是'name1',name2,…。按钮总是以nr结尾,记录道总是有一个从0到n的序列nr“按数字切换记录道”:这正是代码所做的。我不理解问题所在。您好@马克。在
