[Chartjs]-Chart.js: Reverse bar chart with regular bars (Bottom to top instead of top to bottom)

I think you could “invert” your values with 6 minus value for the value you want to display and then override the labels at y-axis

options: {
        scales: {
            yAxes: [{
                ticks: {
                    callback: function(value, index, values) {
                        return (6 - value);
                    }
                }
            }]
        }
