### Steps to Reproduce
(It's related with #11847)
1. I want to show line chart with **one limit line** (ex: yAxis: 300, theres no range data-like max/min-, just one)
2. using `markLine` and `visualMap-pieces` to present limit
3. I can't check line chart

Can confirm. I circumvented the issue by adding a 2nd, "artificial" piece with the same color.
```
pieces: [
{
lte: 180,
color: "#292929",
},
{
gt: 180,
lte: 184,
color: "#292929",
},
{
gt: 184,
color: "#e03131",
},
],
```

@jlefeaux, the trick with a middle piece works, but it displays an extra entry in the legend.
There is **another workaround** - to subtract a small value from the first piece: ```lt:300-0.001```.
Then the legend keeps only original values - [Demo](https://echarts.apache.org/examples/en/editor.html?code=CQOg5gpgLgFASgeQQFQPoAUCCyASACAajwHIB6AEwEMpLTKBne6C62ygRwEsBaAIwk4ArTgDswIQfQD2I4gBo8AMwCuIgMZROMvDCo0AlHgDeAKDx4AtgE8AwgAtKAJyggmUBAAdNMmGfM6pLy0RPABeYz9_PE0oABsIAC4IqKioCAAPKCTiACEBYTE8TABFAEl5SJT4xSySAEYAUmJK8wBfORa8dMx0znok0xT_PUokkZALSg8YFXVvEJhONItDQaH_R2hlRxCliAsAbQAGAF0Abk62_U72zqsevoHboYA3PuVKWIBZKYHL6MCSQArEcOus8I5OGA7LU6qD_h5OBA1BB-ngDv9zGtweZYrUAMxHI7cI4gIl1ME48xqKSxKSObIAYgAnPibABRI4AdmaVOeOKMeEx_jABKJlKpNLpDJIjMwNnxOQATJheTjWv8TjcJf4mJDUX9wSJKBZEiQ8kJRGAimUKuCoFYPGbiPQ1NQ0o47esRmNWBMpjNVBpgjo9itkjjNlBtrtlgc6ud_q19DqopNHABrAAyojN2O9rCSB0F916aMJRzwrS14I1Qzr_mTfn0F2TZyAA).
