两度之间的旋转箭头

如何解决两度之间的旋转箭头

这是我想要箭头作用的伪造的量规

This is the fake gauge I want the arrow to work on

我希望红线/指针随机产生0-100％的湿度。

HTML：

//variables 

let hygrometerHand = document.querySelector("#hygrometerHand");
const button = document.querySelector("#button");
let hygrometerangle = 0;
hygrometerHand = 0;

//function

function generateResult() {
  let min = -100;
  let max = 95;
  let x = Math.random() * (max - min) + min;
  hygrometerHand = x;
  hygrometerHand.style.transform = `rotate(${hygrometerHand}deg)`;
}

//button and event listener to generate moisture reading

button.addEventListener("click",generateResult);

    <div>
      <button id="button">Click here</button>
    </div>
    <script src="main.js"></script>
  </body>
</html>

请对此提供帮助！我知道答案可能会很简单，但这是我在训练营学习JS的第二周，我的想法太繁琐了。

谢谢！
