我正在使用http://www.chartjs.org/上的折线图

正如你可以看到Y轴的最大值(130)和最小值(60)是自动选择的,我想要最大值= 500和最小值=0。这可能吗?

对于Chart.js v3.2.0,这样做:

let options = {
    scales: {
        y: {
            suggestedMin: 0,
            suggestedMax: 69
        },
        x: {
            suggestedMin: 0,
            suggestedMax: 420
        }
    }
}

yAxes: [{
    display: true,
    ticks: {
        beginAtZero: true,
        steps:10,
        stepValue:5,
        max:100
    }
}]

对于chart.js V2 (beta),使用:

var options = {
    scales: {
        yAxes: [{
            display: true,
            ticks: {
                suggestedMin: 0,    // minimum will be 0, unless there is a lower value.
                // OR //
                beginAtZero: true   // minimum value will be 0.
            }
        }]
    }
};

有关线轴配置的详细信息,请参阅chart.js文档。

我写了一个js在y轴上显示从0到100的值,间隔为20。

这是我的script。js

//x-axis var vehicles = ["Trucks", "Cars", "Bikes", "Jeeps"]; //The percentage of vehicles of each type var percentage = [41, 76, 29, 50]; var ctx = document.getElementById("barChart"); var lineChart = new Chart(ctx, { type: 'bar', data: { labels: vehicles, datasets: [{ data: percentage, label: "Percentage of vehicles", backgroundColor: "#3e95cd", fill: false }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero: true, min: 0, max: 100, stepSize: 20, } }] } } });

这是显示在网页上的图表。

var config = { type: 'line', data: { labels: ["January", "February", "March", "April", "May", "June", "July"], datasets: [{ label: "My First dataset", data: [10, 80, 56, 60, 6, 45, 15], fill: false, backgroundColor: "#eebcde ", borderColor: "#eebcde", borderCapStyle: 'butt', borderDash: [5, 5], }] }, options: { responsive: true, legend: { position: 'bottom', }, hover: { mode: 'label' }, scales: { xAxes: [{ display: true, scaleLabel: { display: true, labelString: 'Month' } }], yAxes: [{ display: true, ticks: { beginAtZero: true, steps: 10, stepValue: 5, max: 100 } }] }, title: { display: true, text: 'Chart.js Line Chart - Legend' } } }; var ctx = document.getElementById("canvas").getContext("2d"); new Chart(ctx, config); <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.2.1/Chart.bundle.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <body> <canvas id="canvas"></canvas> </body>

  "options":{
                    scales: {
                                yAxes: [{
                                    display: true,
                                    ticks: {
                                        suggestedMin: 0, //min
                                        suggestedMax: 100 //max 
                                    }
                                }]
                            }
