    scales: {
        yAxes: [
            {
                ticks: {
                    callback: function(label, index, labels) {
                        return label/1000+'k';
                    }
                },
                scaleLabel: {
                    display: true,
                    labelString: '1k = 1000'
                }
            }

        scales: {
            xAxes: [{
                ticks: {
                    autoSkip: false,
                    maxRotation: 90,
                    minRotation: 90
                }
