[Chartjs]-Chartjs bar dataset label not showing

Set autoSkip for xAxis to false :

scales: {
  xAxes: [{
      beginAtZero: true,
      ticks: {
         autoSkip: false
      }
  }]
}

Check your sold1 and sold2.

console.log(sold1);
console.log(sold2);

For example this is working:

var chartdata = {
    {
        type: 'bar',
        data: {
          labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
          // labels: month,
          datasets: [
            {
              label: 'this year',
              backgroundColor: '#26B99A',
              data: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
            },
            {
              label: 'previous year',
              backgroundColor: '#03586A',
              data: [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
            }
          ]
        }
    }
};



var ctx = document.getElementById('chartContainer').getContext('2d');
new Chart(ctx, chartdata);
