BarPercentage Chart js 2- Vue

Question

I'm trying to change width of bar with BarPercentage using Chart.js 2 on Vue.js, but cannot. Don't react to option parametrs(tried to use CategoryPercentage/BarPercentage)

                            this.data[14][4],
                            this.data[15][4],
                            this.data[16][4],
                            this.data[17][4],
                        ],
                        
                    },
                ],
                options: {
                    scales: {
                        yAxes: [{
                            ticks: {
                                
                                beginAtZero: true
                            }
                        }],
                        xAxes: [{

                            barPercentage: 0.9,
                            categoryPercentage: 12.9
                        }]
                    }
                },
            },
            { responsive: true, maintainAspectRatio: false, onClick: this.handle }
        );
    },
