我正在使用两个点绘制x轴，我希望刻度线从原点的左侧和原点的右侧开始，在此处我传递刻度线的值

Question

enter image description here

这是绘制线条和刻度线的代码

 const l = board.create('line', [

    p1, p2
], {
    straightFirst: false,
    straightLast: false,
    strokeColor:'#000',
    withLabel: "true",
    drawZero:false,
    firstArrow: true,
    lastArrow:  true,
    strokeWidth: '1',

});

这用于在行上打勾

const l2 = board.create('ticks', [l], { 
    ticksDistance: diff,
    minorTicks:false,
    // insertTicks: true,
    drawZero: true,
    equidistant: true,
 }
);

//我能够找出使用中点绘制的刻度线
