Echarts中series-line的markLine如何隐藏label?

How to hide label in markLine of series-line in Echarts?

如何在Echarts中隐藏series-line的markLine中的label?或者如何更改标签样式?

我试过 label: false,没用。

series: [
    markLine: {
        silent: true,
        symbol: false,
        label: false,
        data: [{
            yAxis: 100
        }, {
            yAxis: 400
        }],
        lineStyle: {
            normal: {
                type: "solid",
                color: "red"
            }
        }
    }
]

应该是:

series: [
    markLine: {
        label: {
            normal: {
                show: false
            }
        }
    }
]

normal 是未 鼠标悬停 按下 时的样式。否则,它将是 emphasis.
