echarts获取y轴刻度区间y轴刻度间隔y轴刻度值

1、直接上图

 

//1.获取y轴刻度区间

let scope = this.spareChart1.getModel().getComponent('yAxis').axis.scale._extent;

//结果：[0, 3500]

//2.获取y轴刻度间隔/轴距

let interval = this.spareChart1.getModel().getComponent('yAxis').axis.scale._interval;

//结果：500

 

//计算出y轴刻度值

let yAxisData = [];

for (let index = 0; index <= (3500/500); index++) {

    yAxisData.push(index*500)

}

 

 

//结果：[0, 500, 1000, 1500, 2000, 2500, 3000, 3500]
