如何在甜甜圈图形中输入数字?
我需要显示每个元素的百分比。我现在开始看图表JS,可以吗?
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'doughnut',
data: {
labels: [
"Red",
"Blue",
"Yellow"
],
datasets: [
{
data: [300, 50, 100],
backgroundColor: [
"#FF6384",
"#36A2EB",
"#FFCE56"
],
hoverBackgroundColor: [
"#FF6384",
"#36A2EB",
"#FFCE56"
]
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
});

<canvas id="myChart" width="400" height="200"></canvas>
