如何在颤振、x 轴和 y 轴上为图表添加名称？

Question

我一直在使用 Flutter 图表的在线图库 ( https://google.github.io/charts/flutter/gallery.html )，但我正在努力为 x 和 y 轴值添加标题。

有人可以帮助我或告诉我如何将标签添加到图表中吗？

它可能使用behaviors属性，检查代码

 var chart = charts.LineChart(seriesList,
        behaviors: [
          new charts.ChartTitle('Dimension',
              behaviorPosition: charts.BehaviorPosition.bottom,
              titleStyleSpec: chartsCommon.TextStyleSpec(fontSize: 11),
              titleOutsideJustification:
              charts.OutsideJustification.middleDrawArea),
          new charts.ChartTitle('Dose, mg',
              behaviorPosition: charts.BehaviorPosition.start,
              titleStyleSpec: chartsCommon.TextStyleSpec(fontSize: 11),
              titleOutsideJustification:
              charts.OutsideJustification.middleDrawArea)
        ],
        defaultRenderer: new charts.LineRendererConfig(includePoints: true));
