When data are zeros show on y axis only zeros. (ECharts)

Hello everyone here is my axisLabel formatter

      yAxis: {
        show: true,
        type: "value",
        min: 0,
        // max: function (value) {
        //   return Math.ceil(value.max);
        // },
        axisLabel: {
          formatter: (val) => {
            console.log(val);
            return props.time
              ? timeFormatter(val / 1000)
              : Math.ceil(val) + ` ${props.units}`;
          },
        },

This is what I get for my y-axis all 1ones because of Math.ceil

If I don't use my formatter I get this

What I want is if all my data is zero to show zeros on my y-axis

For completeness I'll write a full answer here:

You can specify the smallest interval between two ticks with minInterval. If you set minInterval to 1 your axis should only show 0 and 1.

If you want it to show only 0 you can set showMaxLabel to false.

The default max value seems to be 1. You could also specify a different max value depending on your current maximum data value via max: (value) => value.max + <some_value>.

Here is an example showing only 0 on the yAxis:

import * as echarts from 'echarts';

var chartDom = document.getElementById('main');
var myChart = echarts.init(chartDom);
var option;

option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {
    type: 'value',
    minInterval: 1,
    axisLabel: { showMaxLabel: false }
  },
  series: [
    {
      data: [0, 0, 0, 0, 0, 0, 0],
      type: 'line'
    }
  ]
};

option && myChart.setOption(option);
