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?

从最新版本v3.9.1开始，你可以像这样设置你的比例:
options:{
scales:{
y:{
beginAtZero: true,
max: 500 // values over 500 will be hidden, OR
suggestedMax: 500, // maximum will be 500, unless there is a higher value
}
}
}

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>
对于Chart.js v3.2.0，这样做:
let options = {
scales: {
y: {
suggestedMin: 0,
suggestedMax: 69
},
x: {
suggestedMin: 0,
suggestedMax: 420
}
}
}
文档:https://www.chartjs.org/docs/latest/axes/ axis-range-settings
ChartJS v2.4.0
如2017年2月7日https://github.com/jtblin/angular-chart.js上的例子所示(因为这似乎是经常变化的):
var options = {
yAxes: [{
ticks: {
min: 0,
max: 100,
stepSize: 20
}
}]
}
这将导致5个y轴值如下所示:
100
80
60
40
20
0
对于"chart.js": "^3.6.1"，
options: {
scales: {
y: {
min: 0,
max: 100,
}
}
}
