javascript - 谷歌可视化折线图上的更改轴不一致

Question

我正在研究一个谷歌可视化，其中返回的数据可以有超过 2 个轴。如果超过 2 个，我只显示前 2 个返回并提供用于切换轴的控件。

这是我正在进行的工作... http://jsfiddle.net/benstraw/Lx7w0jgL/

    //Load the Visualisation API and the package you want to use
google.load('visualization', '1.0', {
    'packages': ['corechart']
});

//Set a callback to run with the API is loaded
google.setOnLoadCallback(drawChart);

// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {

如果您关闭数字轴中的项目，并打开百分比轴中的 2 个项目，则切换会正确发生，但是当我将它们切换回来时，数字轴范围是错误的，它具有货币轴的范围.

我不确定为什么，但列号数组乱序似乎会导致问题。我在调用 setColumns 之前添加了 showCols.sort() 行，它似乎已经修复了您在问题中描述的行为。这是一个 fork 的 fiddle http://jsfiddle.net/qf8nL24s/1/
