Question

当我创建普通条形图时，Google会自动分配颜色并且看起来不错：

Non-stacked graph

然而，当我堆叠它们时，它们都是相同的音调并且变得难以阅读。

Stacked graph

如何让每个酒吧的每个部分都有不同的颜色？每页的条形数量都不同，因此不能选择硬编码颜色？

以下是图表的代码。

代码：

      google.setOnLoadCallback(drawChart);

        var chart = new google.charts.Bar(document.getElementById('chart'));

        chart.draw(data, options);
