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

plotly shiny r javascript

Mark · 技术社区 · 7 年前

操作按钮 legend 地位 true/legendonly rendering 的 plotly 而是改变 widget

我的目标是将表示keep/drop集群的按钮链接到两个方向的绘图中的数据的可视化 . 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。

我已经在更大的实际应用程序中为更大的情节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按钮选择要移除哪些集群以进行进一步处理。

感谢上一个问题 here -1单击图例可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每当绘图重新呈现时,它现在也会重新激活每个记录道以前的显示/隐藏状态。

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")

目前还有第三个交互,当用户单击按钮时,它会导致跟踪隐藏起来。这种做法是这里的问题。它目前遵循下图中的橙色流程,但我希望通过一个避免重新呈现绘图的javascript解决方案来改变这一点:

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)

js <- c(
  "function(el, x, plotid){",
  "  var id = el.getAttribute('id');",
  "  if(id == plotid){",
  "    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]);",
  "        }",
  "      });",
  "    });",
  "  }",
  "}")

然后

  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, data = "plot")
  })

如果有多个按钮,则每个跟踪对应一个按钮:

js <- c(
  "function(el, x, plotid){",
  "  var id = el.getAttribute('id');",
  "  if(id == plotid){",
  "    var data = el.data;",
  "    $('[id^=btn]').on('click', function() {",
  "      var index = parseInt(this.id.split('-')[1]);",
  "      var v0 = data[index].visible || true;",
  "      var v = v0 == true ? 'legendonly' : true;",
  "      Plotly.restyle(el, {visible: v}, [index]);",
  "    });",
  "  }",
  "}")

ui <- fluidPage(
  plotlyOutput("plot"),
  actionButton("btn-0", "drat"),
  actionButton("btn-1", "wt")
)

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, data = "plot")
  })

}

shinyApp(ui, server)

这对你的例子不起作用。这是因为按钮是通过 renderUI

我能找到的唯一解决办法是下面这个。我没有在plotly的回调中附加onclick事件侦听器,而是在 onclick

js <- c(
  "function toggleLegend(id){",
  "  var plot = document.getElementById('plot1');",
  "  var data = plot.data;",
  "  var index = parseInt(id.split('-')[1]) - 1;",
  "  var v0 = data[index].visible || true;",
  "  var v = v0 == true ? 'legendonly' : true;",
  "  Plotly.restyle(plot, {visible: v}, [index]);",
  "}")

ui <- fluidPage(
  tags$head(
    tags$script(HTML(js))
  ),
  fluidRow(
    ......

  output$YNbuttons <- renderUI({
    req(values$NrOfTraces)
    lapply(1:values$NrOfTraces, function(el) {
      YNb <- YNElement(el)
      if(values$dYNbs_cyl_el[[YNb]] == TRUE) {
        div(actionButton(inputId = YNb, label = icon("check"), 
                         style = "color: #339FFF;   background-color: white;  border-color: #339FFF;height: 34px; width: 34px; border-radius: 6px;  border-width: 2px; text-align: center;  line-height: 50%; padding: 0px; display:block; margin: 2px", 
                         onclick = "toggleLegend(this.id);"))
      } else {
        div(actionButton(inputId = YNb, label = icon("times"), 
                         style = "color: #ff4d4d;   background-color: white;  border-color: #ff4d4d;height: 34px; width: 34px; border-radius: 6px;  border-width: 2px; text-align: center;  line-height: 50%; padding: 0px; display:block; margin: 2px", 
                         onclick = "toggleLegend(this.id);"))
      }
    })
  })

而且没有使用 onRender .

btn-plot2-5

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]);",
  "}")
