jQuery-如何使用chart.js库在非数字图表中添加工具提示文本？

Question

我已经通过使用jQuery库Chartjs创建了非数字图表  https://www.chartjs.org/docs/latest/。

我想在工具提示文本中动态添加日期，时间，用户名，就像动态创建数据点的方式一样。

代码为

{ 
"to":"eB5papU2Xdc:APA91bFFvc3dXru1fN5JY8U19oHIpfGhPUx7Ll7v9vJYTsIGZ15mDwB2Wpep3flLK85IUqqs2WqJwjYHSDYX28oJ1wTP0R2TDc2ba_uVjUauDcp3pCNKr_0KlghOnS", 
 "notification" : {
 "body" : "New announcement assigned",
 "OrganizationId":"2",
 "content_available" : true,
 "priority" : "high",
 "subtitle":"Elementary School",
 "Title":"hello"
 },
 "data" : {
 "priority" : "high",
 "sound":"app_sound.wav",
 "content_available" : true,
 "bodyText" : "New Announcement assigned",
 "organization" :"Elementary school"
}
}

jQuery

  <canvas id="canvas"></canvas>

问题：是否可以像添加数据点一样动态添加工具提示文本？
