Inline Dose echarts 折线配置项内容和展示

axisLabel of yAxis not bind with yAxis position . 1. when set axisLine.onZero = false, the yAxis is left, works well. 2.when set onZero = true, yAxis is in xAxis 0 label, but the yAxisLabel is on the left. 3. when set yAxis.offset, only works in fixed width, not works well when window resize. 4. yAxis.position only can be set 'left' or 'right', is 'center' ok? I want to set onZero true, the yAxis is on xAxis 0 label ,and the yAxisLabel still in center.

      const data1 = [[-12, 0], [-10, 3], [-8, 5], [-6, 10], [-4, 60], [-2, 99], [0, 100],
    [2, 100], [4, 93], [6, 85], [8, 10], [10, 6], [12, 0] ];
    const data2 = [[-12, 1], [-10, 2], [-8, 6], [-6, 15], [-4, 70], [-2, 95], [0, 110],
    [2, 100], [4, 90], [6, 80], [8, 20], [10, 4], [12, 0] ];
