无法使用D3进行分配线图



var margin = {
    top: 30,
    right: 20,
    bottom: 30,
    left: 50
};
var width = 600 - margin.left - margin.right;
var height = 270 - margin.top - margin.bottom;
var x = d3.scale.linear().range([0, width]);
var y = d3.scale.linear().range([height, 0]);
var xAxis = d3.svg.axis().scale(x)
    .orient("bottom").ticks(5);
var yAxis = d3.svg.axis().scale(y)
    .orient("left").ticks(5);
var valueline = d3.svg.line()
    .x(function (d) {
      return x(d.IP);
    })
    .y(function (d) {
      return y(d.count);
    });
var svg = d3.select("body")
    .append("svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
    .append("g")
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")");
var data = [{
    "IP": "192.168.12.1",
    "count": "100"
}, {
    "IP": "76.09.45.34",

请帮助我。我被困。我不知道如何使用这些代码获取x axis line Graph 。我是D3的新手,所以我很困惑。每次我进行更多更改时,轴都会熄灭。这些是我到目前为止尝试的最后一个代码,但我只得到y axis及其标签,但没有x axis,并且该行也没有被绘制。请帮助我。预先感谢。

而不是预期仅整数范围的Linear scale,因此您需要将ordinal scale用于X轴。

var x = d3.scale.ordinal().range([0, width]);
var y = d3.scale.linear().range([height, 0]);
var xAxis = d3.svg.axis().scale(x)
    .orient("bottom").ticks(5);
var yAxis = d3.svg.axis().scale(y)
    .orient("left").ticks(5);
x.domain(data.map(function(d) {
        return d.IP;
    }))
    .rangeRoundBands([0, width], 0.1); 
y.domain([0, d3.max(data, function (d) {
    return d.count;
    })]);

这是您的工作代码。

您必须使用x轴的顺序尺度。

序数尺度具有离散域,例如一组名称或 类别。

这是工作代码段:

var margin = {
  top: 30,
  right: 20,
  bottom: 30,
  left: 50
};
var width = 600 - margin.left - margin.right;
var height = 270 - margin.top - margin.bottom;
var x = d3.scale.ordinal().rangePoints([0, width]);
var y = d3.scale.linear().range([height, 0]);
var xAxis = d3.svg.axis().scale(x)
  .orient("bottom").ticks(5);
var yAxis = d3.svg.axis().scale(y)
  .orient("left").ticks(5);
var valueline = d3.svg.line()
  .x(function(d) {
    return x(d.IP);
  })
  .y(function(d) {
    return y(d.count);
  });
var svg = d3.select("body")
  .append("svg")
  .attr("width", width + margin.left + margin.right)
  .attr("height", height + margin.top + margin.bottom)
  .append("g")
  .attr("transform", "translate(" + margin.left + "," + margin.top + ")");
var data = [{
  "IP": "192.168.12.1",
  "count": "100"
}, {
  "IP": "76.09.45.34",
  "count": "200"
}, {
  "IP": "34.91.23.76",
  "count": "300"
}, {
  "IP": "192.168.19.32",
  "count": "400"

}, {

  "count": "600"
}];
data.forEach(function(d) {
  d.IP = d.IP;
  d.count = +d.count;
});
x.domain(data.map(function(d) {
  return d.IP
}));
y.domain([0, d3.max(data, function(d) {
  return d.count;
})]);
svg.append("path")
  .attr("d", valueline(data));
svg.append("g")
  .attr("class", "x axis")
  .attr("transform", "translate(0," + height + ")")
  .call(xAxis);
svg.append("g")
  .attr("class", "y axis")
  .call(yAxis);

.axis path,
.axis line {
