[Solved]-Decimals on yAxis are not being displayed, even if that same code works on highcharts jsfiddle-Highcharts

I have no idea why the same chart options are shown differently in jsfiddle and your environment. However, you can customize yAxis labels using yAxis.labels.formatter function. There you should have access to values with decimals. Check demo I posted you below.

  formatter: function() {
    return this.value.toFixed(2);
  }
