    scales: {
        yAxes: [{
            display: true,
            ticks: {
                beginAtZero: true,   // minimum value will be 0.
              	// <=> //
              	min: 0,
              	max: 10,
              	stepSize: 1 // 1 - 2 - 3 ...
            }

            display: true,
            ticks: {
                suggestedMin: 0,    // minimum will be 0, unless there is a lower value.
                // OR //
                beginAtZero: true   // minimum value will be 0.
            }
