Steps to reproduce

myChart.setOption({
    series:[
        {
        sampling: 'lttb',
        type: 'line',
        data: Array.from(new Array(2000)).map((x, i) => [i, Math.floor(Math.random() * (5 - 1   1))   1]),
    },
    {
        sampling: 'lttb',
        type: 'line',
        data: Array.from(new Array(2000)).map((x, i) => [i, Math.floor(Math.random() * (10 - 1   1))   1]),
    }
        ],
    xAxis:[{type:'value'}],
    yAxis:[{type:'value', max: 15, min: 0}],
    tooltip: {
        trigger: 'axis',
    },
    dataZoom: [
        {
        xAxisIndex: [0, 1],
        type: 'inside',
        filterMode: 'filter'
