如何在ASP.NET JavaScript中使用Google Charts API仅对绘制为负方向的条形图移动堆叠条形图标签位置

我正在制作一个堆叠的条形图，比较两个不同年份的季度业绩.一年绘制为正值条形图，第二年使用结果值*-1绘制，因此它绘制在同一季度以下.

在本例中，2023年QTR1为469,2022年QTR1实际为676.在查询过程中，最低年份值乘以-1.

如何使负值显示在底部栏的下方，并使正值保持在顶部，就像现在一样？

JavaScript:如下所示:

 <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
 <script type="text/javascript">

     google.charts.load('current', { packages: ['corechart'] });
     google.charts.setOnLoadCallback(drawChart);

     function drawChart() {
         var data = new google.visualization.DataTable();

         var jsonList = @(Json.Serialize(Model.listAllAircraftChartQuarterly))

         var title = 'Quarterly Aircraft Transaction Trend';

         data.addColumn('string', 'Quarter');
         data.addColumn('number', '2023');
         data.addColumn('number', '2022');
         data.addColumn('number', '% Change');
         data.addRows(jsonList.map((p) => {
             return [p.yearQuarter, p.year2top, p.year3bottom, p.year2percent];
         }));

         var formatPercent = new google.visualization.NumberFormat({ pattern: '#.#%' });
         formatPercent.format(data, 3);

         var view = new google.visualization.DataView(data);
         view.setColumns([0, 1,
             {

         window.addEventListener('resize', drawChart, false);
