Question

由于一个完全逃避我的原因，我无法使maxValue vAxis属性工作：

var options = { vAxis: { maxValue: .85 } }

vAxis是一个范围为0到100％的百分比，我想通过将最大值设置为85％来节省一些空间。我认为这与7 DataSources和4 ChartTypes之间的项目切换有关，因为我制作单个图表时从未遇到过这个问题。

以下代码段是一个简化案例，具有可能与问题相关的最小功能。感谢您的时间和精力。

Answer 1

你可以用 - ＆gt;覆盖vAxis.viewWindow.max

  vAxis: {
      viewWindow: {
          max: 0.85
      }
      ...

此外，vAxis.maxValue仅适用于continuous axis ...

Google Visualization - vAxis maxValue属性不起作用
