jQuery滑块不与使用d3垂直线绘制的数据交互

问题描述

我正在尝试让我的数据与jQuery滑块进行交互。 “我的数据”用steelblue的竖线表示，但是jQuery滑块仅与浅灰色的竖线xAxis交互，因为我使用xAxis x.axis及其路径对其进行了设置。它仅随滑块移动，而不会随着steelblue中的实际垂直线移动。我无法使用d3滑杆，并且无法使用此d3 v2。我问了一个关于竖线的问题：（How to interact JQuery slider with d3 vertical lines for every data point），但是建议对这个滑块问题提出一个单独的问题:(任何输入都会有所帮助！这是代码：

// define dimensions of graph
var m = [80,80,80]; // margins
var w = 1000 - m[1] - m[3]; // width
var h = 350 - m[0] - m[2]; // height

// create a simple data array that we'll plot with a line (this array represents only the Y values,X will just be the index location)
var data = [0];
for (var i = 1; i < 50; i++) {
  var sign = Math.random() > 0.5 ? +1 : -1;
  data.push(data[i - 1] + sign * Math.random());
}

// X scale will fit all values from data[] within pixels 0-w
var x = d3.scale.linear().domain([0,data.length]).range([0,w]);
// Y scale will fit values from 0-10 within pixels h-0 (Note the inverted domain for the y-scale: bigger is up!)
var y = d3.scale.linear().domain([d3.min(data),d3.max(data)]).range([h,0]);

// Add an SVG element with the desired dimensions and margin.
var graph = d3.select("#graph").append("svg:svg")
  .attr("width",w + m[1] + m[3])
  .attr("height",h + m[0] + m[2])
  .append("svg:g")
  .attr("transform","translate(" + m[3] + "," + m[0] + ")");

// create yAxis
var xAxis = d3.svg.axis().scale(x).tickSize(-h).tickSubdivide(3);
// Add the x-axis.
graph.append("svg:g")
  .attr("class","x axis")
  .attr("transform","translate(0," + h + ")")
  .call(xAxis);

// create left yAxis
var yAxisLeft = d3.svg.axis().scale(y).ticks(4).orient("left");
// Add the y-axis to the left
graph.append("svg:g")
  .attr("class","y axis")
  .attr("transform","translate(-25,0)")
  .call(yAxisLeft);

var circle = graph.selectAll("circle")
  .data(data);

circle.enter()
  .append("circle")
  .attr("cx",function(d,i) {
    return x(i)
  })
  .attr("cy",function(d) {
    return y(d)
  })
  .attr("class","circle")
  .attr("r",2)
  .attr("fill","red");

var verticalLine = graph.selectAll(".vertical-line")
  .data(data);

verticalLine.enter()
  .append("line")
  .attr("x1",i) {
    return x(i)
  })
  .attr("x2",i) {
    return x(i)
  })
  .attr({
    y1: 0,y2: h,stroke: 'steelblue',class: 'vertical-line'
  });

function zoom(begin,end) {
  x.domain([begin,end - 1]);

  var t = graph.transition().duration(0);

  var size = end - begin;
  var step = size / 10;
  var ticks = [];
  for (var i = 0; i <= 10; i++) {
    ticks.push(Math.floor(begin + step * i));
  }

  xAxis.tickValues(ticks);

  t.select(".x.axis").call(xAxis);
  t.select('.path').attr("d",verticalLine);
}

$(function() {
  $("#slider-range").slider({
    range: true,min: 0,max: 1000,values: [0,1000],slide: function(event,ui) {
      var begin = d3.min([ui.values[0],data.length]);
      var end = d3.max([ui.values[1],0]);
      console.log("begin:",begin,"end:",end);

      zoom(begin,end);
    }
  });
});
