使用线性轴模仿对数轴展示数据的demoecharts 配置项内容和展示

使用线性轴模仿对数轴展示数据的demo，规避对数轴无法展示为0数据的问题，支持非负数

      let chartData = [0.003, 2000, 80000, 4, 19, 33, 0];

let logBase = 10;

let max = Math.max(...chartData);

let min = Math.min(...chartData.filter(e => e > 0));

let dMax = 0;

let dMin = 0;

while (Math.pow(logBase, dMax) <= max) {
    dMax++;
}

while (Math.pow(logBase, dMin) >= min && dMin > -10) {
    dMin--;
}

let interval = logBase / Math.abs(dMax);
