javascript - chart.js 响应条形图标签大小

Question

所以我有一个使用 chart.js 的条形图，并且启用了响应。它似乎适用于某些图表，但不适用于其他图表。例如，我的条形图标签似乎没有随窗口调整大小，但其他一切确实使整个图表在较小的窗口尺寸下看起来非常奇怪。我怎样才能重新调整标签的大小，以便它们一起缩放？有任何想法吗？谢谢!

HTML:

<canvas id="canvas" width="940" height="540"></canvas>

JS:

var barChartData = {
    labels: ["Adjust claims fairly", "Pays promptly", "Resolves issues quickly", "Communicates clearly, honestly to agents", "Underwriter knowledge/expirience", "Listens, responds to agents", "Consistant underwriting", "Easy, intuitive functionality-technology", "Stable underwriting market", "Flexible underwriting when warrented"],
    datasets: [
        {
        label: "My First dataset",
        //new option, barline will default to bar as that what is used to create the scale
        type: "line",
        fillColor: "rgba(225,225,225,0.01)",
        strokeColor: "rgba(0,0,0,1)",
        pointColor: "rgba(0,0,0,1)",
        pointStrokeColor: "#000000",
        pointHighlightFill: "#fff",
        pointHighlightStroke: "rgba(0,0,0,1)",
        data: [9.5, 9.4, 9.3, 9.2, 9.2, 9.1, 9, 9, 9, 9]
    }, {
        label: "My First dataset",
        //new option, barline will default to bar as that what is used to create the scale
        type: "bar",
        fillColor: "rgba(225,50,50,0.8)",
        strokeColor: "rgba(225,50,50,1)",
        pointColor: "rgba(220,20,220,1)",
        pointStrokeColor: "#fff",
        pointHighlightFill: "#fff",
        pointHighlightStroke: "rgba(220,220,220,1)",
        data: [7.4, 7.6, 6.2, 6.3, 6.8, 5.8, 7.1, 6.1, 7.6, 5.2]
    }]
};
Chart.defaults.global.responsive = true;
//canvases
var lineBar = document.getElementById("canvas").getContext("2d");

//charts
var myLineBarChart = new Chart(lineBar).Overlay(barChartData);

Answer 1

这个问题更多地与真正长的 x 轴标签有关，而不是与响应能力有关。也就是说，设置 maintainAspectRatio 将解决您的问题。

Chart.defaults.global.maintainAspectRatio = false;

请注意，您也可以针对每个图表执行此操作。
