javascript - D3 JS 附加到 div 奇怪的结果

Question

你好，我遇到了一个相当奇怪的问题。我有一个图表，当它附加到正文时可以工作。当我将其更改为附加到 div 时，会发生这种情况:普通的![正常状态] /image/SCiuG.jpg附加到 div![div 状态] /image/SDdsC.jpg

我注意到轴没有正确绘制，但不知道如何解决这个问题。

有一次它保持正常，更新后它会随着正确的轴而变小。

我的代码:

// Set the dimensions of the canvas / graph
var margin = {top: 15, right: 10, bottom: 30, left: 50},
    width = 400 - margin.left - margin.right,
    height = 220 - margin.top - margin.bottom;

// Parse the date / time
var parseDate = d3.time.format("%d-%b-%y").parse;

// Set the ranges
var x = d3.time.scale().range([0, width]);
var y = d3.scale.linear().range([height, 0]);

// Define the axes
var xAxis = d3.svg.axis().scale(x)
    .orient("bottom").ticks(5);

var yAxis = d3.svg.axis().scale(y)
    .orient("left").ticks(5);

// Define the line
var valueline = d3.svg.line()
.interpolate("basis") 
    .x(function(d) { return x(d.date); })
    .y(function(d) { return y(d.close); });

// Define the second line
var valueline2 = d3.svg.line()
.interpolate("basis") 
    .x(function(d) { return x(d.date); })
    .y(function(d) { return y(d.open); });

// Define the second line
var valueline3 = d3.svg.line()
.interpolate("basis") 
    .x(function(d) { return x(d.date); })
    .y(function(d) { return y(d.open2); });

// Define the second line
var valueline4 = d3.svg.line()
.interpolate("basis") 
    .x(function(d) { return x(d.date); })
    .y(function(d) { return y(d.open3); });

// Adds the svg canvas
var svg = d3.select("#biggraph")
        .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 + ")");

// Get the initial data
d3.tsv("data/data2.tsv", function(error, data) {
    data.forEach(function(d) {
        d.date = parseDate(d.date);
        d.close = +d.close;
        d.open = +d.open;
        d.open2 = +d.open2;
        d.open3 = +d.open3;
    });

    // Scale the range of the data
    x.domain(d3.extent(data, function(d) { return d.date; }));
    y.domain([0, d3.max(data, function(d) { return Math.max(d.close, d.open, d.open2, d.open3); })]);

    // Add the valueline path.
    svg.append("path")
        .attr("class", "line")
        .attr("d", valueline(data));

     // Add the valueline2 path.
     svg.append("path")     
        .attr("class", "line2")
        .style("stroke", "red")
        .attr("d", valueline2(data));  

     // Add the valueline3 path.
     svg.append("path")     
        .attr("class", "line3")
        .style("stroke", "#FF6600")
        .attr("d", valueline3(data)); 


     // Add the valueline4 path.
     svg.append("path")     
        .attr("class", "line4")
        .style("stroke", "green")
        .attr("d", valueline4(data)); 

    // Add the X Axis
    svg.append("g")
        .attr("class", "x axis")
        .attr("transform", "translate(0," + height + ")")
        .call(xAxis);

    // Add the Y Axis
    svg.append("g")
        .attr("class", "y axis")
        .call(yAxis);

});

// ** Update data section (Called from the onclick)
function updateData() {

    // Get the data again
    d3.tsv("data/data-alt2.tsv", function(error, data) {
        data.forEach(function(d) {

我已经找到问题的答案了。这是同一页面上另一个数据流的问题。重命名后问题就解决了。
