使chartsJS条形图从y轴开始

options: {
  scales: {
    y: {
      beginAtZero: true
    }
  }
}

var chart = new Chart(ctx, {
  type: 'bar',
  data: {
    labels: ['A', 'B', 'C', 'D', 'E'],
    datasets: [{
      label: 'Data',
      data: [10, 20, 30, 40, 50],
      backgroundColor: 'rgba(0, 123, 255, 0.5)'
    }]
  },
  options: {
    scales: {
      y: {
        beginAtZero: true
      }
    }
  }
});
