angularjs - 谷歌柱形图条宽

Question

我有 angular2 和谷歌图表。

我的组件代码是：

playstoreRatingChart(data) {
        let dateTitle: any = 'Date';
        let ratingTitle: any = 'Rating';
        let dataTable = [[dateTitle, ratingTitle,  { "role": 'annotation' }, { role: 'style' }]];

        data.playstore_rating.forEach(function (obj) {
            let newDate = new Date(obj.year, obj.month-1, obj.day)
            let rating = obj.rating;
            let rowRating = Number(rating.toFixed(2));
            let test = parseFloat(rating.toFixed(2));
            let row = [newDate, test, test, 'width:22; stroke-color: #871B47; stroke-opacity: 0.6; stroke-width: 12; fill-color: #BC5679; fill-opacity: 0.2'];
            dataTable.push(row)
        });

        this.testPlayStore = {
            chartType: 'ColumnChart',
            dataTable: dataTable,
            bar: { groupWidth: '100%' }
        }
    }

我不知道，为什么，但正是这个图表（我在这个页面上还有几个图表）有 1px 宽度的列，我不能改变它的宽度。
