d3.js - d3折线图中显示的随机水平线？

转载作者：行者123 更新时间：2023-12-04 09:02:42

我将数据绘制为折线图，出于某种原因，有随机水平线穿过图形的一部分:

我正在像这样绘制我的数据:

const timeConv = d3.timeParse("%Y-%m-%dT%H:%M:%S.%f");
const width = 960;
const height = 500;
const margin = 5;
const padding = 5;
const adj = 30;

/* adding svg */
const svg = d3.select("#chart").append("svg")
    .attr("preserveAspectRatio", "none")
    .attr("viewBox", "-"
          + adj + " -"
          + adj + " "
          + (width + adj * 3) + " "
          + (height + adj * 3))
    .attr("height", "100%")
    .style("padding", padding)
    .style("margin", margin)

/* sanitizing data */
const dataset = d3.json("formattedStats.json")
dataset.then(function(data) {
/* scaling */
    const xScale = d3.scaleTime().range([0, width]);
    const yScale = d3.scaleLinear().rangeRound([height, 0]);
    xScale.domain(d3.extent(data, d => timeConv(d.dateCreated)));
    yScale.domain([
        0,
        d3.max(data, d => d.balance)
    ]);

    const yaxis = d3.axisLeft()
        .ticks(20)
        .scale(yScale);

    const xaxis = d3.axisBottom()
        .ticks(d3.timeDay.filter(d => d3.timeDay.count(0, d) % 3 === 0))
        .tickFormat(d3.timeFormat('%b %d'))
        .scale(xScale);

    svg.append("g")
        .attr("class", "axis")
        .attr("transform", "translate(0," + height + ")")
        .call(xaxis);

    svg.append("g")
        .attr("class", "axis")
        .attr("transform", "translate(0, 0)")
        .call(yaxis);


    const line = d3.line()
        .x((d) => xScale(timeConv(d.dateCreated)))
        .y((d) => yScale(d.balance));

    svg.append("path")
      .attr("d", line(data))
      .attr("stroke", "black")

});

我的数据如下所示:

有谁知道为什么会发生这种情况？谢谢!

最佳答案

这种错误(图形/图表线/矩形/路径/圆圈在很大程度上是正确的，但有一个或两个错误的点)通常可以追溯到以下两个问题之一:

数据错误

解析数据时出错

在您的情况下，数据很好，但您对它的解析并没有考虑边缘情况，当您的时间没有毫秒时，请比较:

const timeConv = d3.timeParse("%Y-%m-%dT%H:%M:%S.%f");
console.log(timeConv("2020-07-19T04:50:29"));
console.log(timeConv("2020-07-19T04:52:21.601"));

<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/5.7.0/d3.min.js"></script>

在您的情况下，对于一个数据点， d3.timeParse 在您的情况下为一个数据点返回一个空值，从而导致路径的 x 值严重缩放。
想到了两个解决方案，修复数据以便按预期格式化该点，或者创建第二个时间解析器来解决这种边缘情况:

.x((d) => xScale(timeConv(d.dateCreated) || timeConvEdgeCase(d.dateCreated)))

这似乎比确保格式一致的数据更黑客，但根据您的数据源，这可能需要内联或在浏览器中加载数据。
