[Solved]-How to make label in highcharts area graph display absolute values instead of negative values?-Highcharts

But what is the sense of creating this kind of chart? If the value goes down, must be lower than other values otherwise, the readability is fake... Of course, it is possible to achieve it by doing some custom changes in the output:

  tooltip: {
    formatter() {
      return `${this.series.name}: ${Math.abs(this.y)}`
    }
  },

  yAxis: {
    labels: {
            formatter() {
                return Math.abs(this.value)
            }
    },
  },
