Expected behavior Be able to get information on clicked bar chart to show more details Actual behavior nothing happens on click, get error in edge console Uncaught TypeError: myChart.getElementsAtEvent is not a function Resources (screenshots, code snippets etc.)

var myChart = new mdb.Chart(canvas, { type: 'bar', data: { labels: aDaysList, datasets: [{ label: 'Antall innlogginer', data: aData, backgroundColor: aBackgroundColor, borderColor: aBorderColor, borderWidth: 1 }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero:true, steps: 10, stepValue: 5, max: iMaxLogin
} }] } } });

    canvas.addEventListener("click", function(evt) {
        var activePoints = myChart.getElementsAtEvent(evt);
        if (activePoints[0]) {
            var chartData = activePoints[0]['_chart'].config.data;
            var idx = activePoints[0]['_index'];

            var label = chartData.labels[idx];
            var value = chartData.datasets[0].data[idx];
            var color = chartData.datasets[0].backgroundColor[idx];
