<script type="text/javascript">
window.onload = function () {
var chart = new CanvasJS.Chart("chartContainer", {
title:{
text: "indexLabel wrap in doughnut",
fontSize: 20,
},
animationEnabled: true,
data: [
{
type: "doughnut",
startAngle: 270,
innerRadius: 80,
indexLabel: " #percent %",
indexLabelFontColor : "black",
indexLabelPlacement: "outside",
indexLabelWrap: true ,
dataPoints: [
{ y: 280, label : "some label" },
{ y: 148,label : "other label" },
{ y: 16, label : "some other label"},
{ y: 32, label : "label" } ,
{ y: 12, label : "label" }
]

</script>

由于空间限制，似乎跳过了indexLabels，即当您通过设置startAngle旋转圆环并设置宽度时，特定数据点的indexLabel没有空间。通过将startAngle更改为几个值或通过增加宽度，可以显示更多indexLabel。这是更新的代码：
var chart = new CanvasJS.Chart("chartContainer", {
title:{
text: "indexLabel wrap in doughnut",
fontSize: 20,
},
animationEnabled: true,
data: [
{
type: "doughnut",
startAngle: 320,
innerRadius: 80,
indexLabel: " #percent %",
indexLabelFontColor : "black",
indexLabelPlacement: "outside",
indexLabelWrap: true ,
dataPoints: [
{ y: 280, label : "some label" },
{ y: 148,label : "other label" },
{ y: 16, label : "some other label"},
{ y: 32, label : "label" } ,
{ y: 12, label : "label" }
]
}
]
});
chart.render();<script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
<div id="chartContainer" style="height: 460px; width: 460px;"></div>
