在水平线规中添加标签

Question

我有这个用于水平线性规的js代码，想在指针上添加标签。

仪表上的指针（var gaugePoint）将是动态的，但我希望将图表please check

而不是图表上的线变成字符串或盒子

var canvas = document.getElementById('canvas');
var stops = [
[-70, "#CC5151"],
[0, "#ffc107"],
[70, "#47B155"]
]

var gaugePoint = 50;
var gaugePoint2 = -25;

new SentimentMeter.LinearGauge(canvas,-100,100)
    .draw(stops)
    .drawPointer(gaugePoint, '#fff', 10)
    .drawPointer(gaugePoint2, '#fff', 10)

This is the gauge i have now with 2 white pointer.

有可能吗？
