Hello, I would like to create a double bar graph that updates depending on what I choose in a select. The update works but I can't put my columns next to each other, instead the columns are stacked.

const chart = document.getElementById('chartMonth'); const chartInstance = new mdb.Chart(chart, { type: 'bar' }); const labels = ['Oct.', 'Nov.', 'Déc.', 'Janv.','Févr.','Mars','Avr.','Mai','Juin','Juill.','Août','Sept.'];   chartInstance.update({
                labels,
                datasets: [
                    {
                        color: '#ba2520',
                        data: [resultat[0][1], resultat[1][1], resultat[2][1], resultat[3][1], resultat[4][1], resultat[5][1], resultat[6][1], resultat[7][1], resultat[8][1], resultat[9][1], resultat[10][1], resultat[11][1]],
                        label: 'Débit',
                    },
                    {
                        color: '#ba2520',
                        data: [resultat[0][1], resultat[1][1], resultat[2][1], resultat[3][1], resultat[4][1], resultat[5][1], resultat[6][1], resultat[7][1], resultat[8][1], resultat[9][1], resultat[10][1], resultat[11][1]],
                        label: 'Débit',
                    },
                ],
            });
