title: My Slider from material ui isn't continuous
body: <pre><code>      &lt;Slider
          min={-10}
          max={10}
          style={{
            width: slider_width ? slider_width : &quot;100px&quot;,
            color: &quot;gray&quot;,
            marginLeft: &quot;10px&quot;,
            marginRight: &quot;10px&quot;,
          }}
          defaultValue={0}
          aria-labelledby=&quot;continuous-slider&quot; // &quot;discrete-slider-always&quot;
          // step={1}
          valueLabelDisplay=&quot;on&quot;
          value={value}
          track={false}
          onChange={check_color}
          ref={value_slider}
        /&gt;
  </code></pre>
  <pre><code>  const [value, set_value] = useState(0);
    const check_color = (e, v) =&gt; {
      set_value(v);
    };
  </code></pre>
  <p>Why isn't it continuous? How do I make it so?</p>
