javascript - chart.js响应式条形图标签大小

所以我有一个使用chart.js的条形图，并且启用了响应。它似乎与某些图表配合良好，而与另一些图表配合却不太理想。例如，我的条形图标签似乎没有随窗口调整大小，但是其他所有操作确实使整个图表在较小的窗口大小下显得很奇怪。如何调整标签的大小，以便一起缩放？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);

最佳答案

这个问题与真正长的x轴标签有关，而不是响应能力。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。



如果您也想保持宽高比，则可以扩展图表以修剪标签，例如https://stackoverflow.com/a/31699438/360067
