echarts獲取y軸刻度區間y軸刻度間隔y軸刻度值

1、直接上圖

 

//1.獲取y軸刻度區間

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

//結果：[0, 3500]

//2.獲取y軸刻度間隔/軸距

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

//結果：500

 

//計算出y軸刻度值

let yAxisData = [];

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

    yAxisData.push(index*500)

}

 

 

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