D3.js中的折线图未正确绘制

我使用this绘制了折线图。在这里我做了一些改变。我把一些数据放在body标签里面。然后，我将时间设置为y轴的x轴和真/假值。我使用常规experssion获得数据集的时间值。通过查看以下代码，这将很容易理解。当有评论数据集（在这个代码中）时，它会很好地淹没，但是在更改后它不起作用？请帮助我确定我所做的错误。D3.js中的折线图未正确绘制

var margin = {top: 20, right: 100, bottom: 30, left: 100}, 
 
    width = 960 - margin.left - margin.right, 
 
    height = 500 - margin.top - margin.bottom;

您是否尝试过调试？你有错误吗？ – Marc

@Marc：不，没有错误。它显示了阵列也不是空的。 –

你的正则表达式好吗？它是否会返回预期的数据值？做一个简单的写检查它。如果不是，这完全是一个与从你的源头提取数据有关的问题。 –

首先，为什么你的数据分析包裹在一个setInterval（这是某种形式的循环尝试的？）。您的分析将在绘制图形后开始（并且dataset将为空数组）。清理它（你当前的解析被破坏了），你可以简化：

var parseDate = d3.time.format("%Y-%m-%d %H:%M:%S").parse, 
    dataset = [], 
    mainRootID = 1; 

// select all lis that have an id or T or F 
d3.selectAll('li#T,li#F').each(function() { 

    // self will be d3 selector with the li 
    var self = d3.select(this), 
    // textData is the contents of the a tag 
    textData = self.select('a').text().replace(/^\s+|\s+$/g, '').split(" "), 
    // this is the id of lis parent div 
    listID = d3.select(this.parentNode).attr('id'); 

    dataset.push({ 
    x: parseDate(textData[0] + " " + textData[1]), // parse to date 
    y: self.attr("id") === "T", // figure out if its t or f 
    testcase: 'TestSuite:' + mainRootID + ' test:' + listID 
    }); 

}); 

// sort the data 
dataset.sort(function(d1,d2){ 
    return d1.x < d2.x; 
})

之后，理顺了，图形又回来了。

我使用了setInterval函数，因为我需要在一段时间内更新折线图。感谢您的代码....我可以在setInterval函数内做到这一点？然后每次在函数内部更新数组并显示与之对应的图形。这是做这个任务的方式，还是有最简单的方法呢？ –

@DesiDelite，你的'uls'更新中的数据是如何的？现在看来，你只需重复解析相同的数据... – Mark

是否有任何可能的方法在setInterval函数内执行此任务？ –
