javascript - Chart.js Bar Chart: How to remove space between the bars in v2.3?

Question

I'm trying to remove the space between my bar chart bars, but even though I see this solution many places it doesn't work for me. It's also not mentioned in the Chart.js docs so that is odd. Can someone tell me how to specify it?

var options = {
    barValueSpacing : 1,        // doesn't work; find another way
    barDatasetSpacing : 1,      // doesn't work; find another way

    legend: {
        display: false          // Hides annoying dataset label
    },
    tooltips: {
        callbacks: {
            label: function(tooltipItem) {
                return tooltipItem.yLabel;
            }
        }
    }
};

var ctx = document.getElementById("canvasX").getContext("2d");          
var myBarChart = new Chart(ctx, {
    type: 'bar',
    data: data,
    options: options
});

You need to set barPercentage and categoryPercentage to 1.0 on the x-axis scale. Add this to your options object:

var options = {
    ...
    scales: {
        xAxes: [{
            categoryPercentage: 1.0,
            barPercentage: 1.0
        }]
    }
};
