我使用Chart Js创建了一个图表。但是,如下所示,图表不适合宽度。 canvas
的属性也不起作用。似乎height
有效,但我无法修改width
(即使我更改了值,它也没有那个值)。我将maintainAspectRatio
设为false,reponsive
为true,但无效。
如何使图表适合设定的宽度和高度?
任何建议或意见都将不胜感激。
<canvas id="monthly-sales" width="300" height="200"></canvas>
JS
var monthlySales = document.getElementById("monthly-sales").getContext('2d');
var monthlySalesChart = new Chart(monthlySales, {
type: 'bar',
data: {
labels: listOfMonths.slice(10,2),
datasets: [{
label: 'Sales',
data: [
monthlyFees['sales'][10],
monthlyFees['sales'][11]
],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
],
borderWidth: 1,
}]
},
options: {
title: {
display: true,
text: 'Sales'
},
legend: {
display: false,
},
maintainAspectRatio: false,
scales: {
yAxes: [{
ticks: {
beginAtZero:true,
userCallback: function userCallback(tick) {
return (tick / 100000000);
}
}
}]
},
tooltips: {
callbacks: {
label: function label(tooltipItem, data) {
return numeral(tooltipItem.yLabel).format('0,0');
}
}
}
}
});

我发现了这个问题。由于未正确定义labels
,因此未正确绘制图表。
