我想设置未填充栏的背景颜色，它必须看起来像这样：[！[在此处输入图片描述] [1]] [1]

这是数据集：

            labels: [
                "Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"
            ],datasets: [
                {
                    fill: true,fillColor: "rgba(220,220,0)",backgroundColor: color(
                        this.layoutConfigService.getconfig("colors.state.brand")
                    )
                        .alpha(1)
                        .rgbString(),pointHoverRadius: 6,pointHoverBorderWidth: 30,pointBackgroundColor: Chart.helpers
                        .color("#000000")
                        .alpha(0)
                        .rgbString(),pointHoverBackgroundColor: this.layoutConfigService.getconfig(
                        "colors.state.brand"
                    ),data: [
                        {
                            y: 20,menuItem: "Beef",description: "At vero eos et accusamus et iusto"
                        },{
                            y: 40,menuItem: "Pizza",{
                            y: 50,menuItem: "Burger",{
                            y: 25,menuItem: "Shrimps",{
                            y: 35,menuItem: "Soup",{
                            y: 60,menuItem: "Tofu",{
                            y: 30,menuItem: "Spaghetti",description: "At vero eos et accusamus et iusto"
                        }
                    ]
                }
            ]
        };```
