使用dataset时，无法设置2个Y轴各自的最大值

[xmwgp8]

One-line summary [问题简述]

就在官方示例的数据调整：

option = {
legend: {},
tooltip: {},
dataset: {
source: [
['product', '2015', '2016'],
['Matcha Latte', 43.3, 1185.8],
['Milk Tea', 83.1, 1173.4],
['Cheese Cocoa', 86.4, 1165.2],
['Walnut Brownie', 72.4, 1153.9]
]
},
xAxis: {type: 'category'},
yAxis: [{name:'2015',
type:'value',
max: function(value) {
return value.max;
}
},
{name:'2016',
type:'value',
max: function(value) {
return value.max ;
}}],
// Declare several bar series, each will be mapped
// to a column of dataset.source by default.
series: [
{type: 'bar'},
{type: 'line'}
]
};

Expected behaviour [期望结果]

2个Y轴根据各自序列的最大值显示。

OK.
series: [
{type: 'bar'},
{type: 'line',yAxisIndex: 1}
]
