官方有例子，是不是你用错了

dataset: {
// 这里指定了维度名的顺序，从而可以利用默认的维度到坐标轴的映射。
// 如果不指定 dimensions，也可以通过指定 series.encode 完成映射，参见后文。
dimensions: ['product', '2015', '2016', '2017'],
source: [
{product: 'Matcha Latte', '2015': 43.3, '2016': 85.8, '2017': 93.7},
{product: 'Milk Tea', '2015': 83.1, '2016': 73.4, '2017': 55.1},
{product: 'Cheese Cocoa', '2015': 86.4, '2016': 65.2, '2017': 82.5},
{product: 'Walnut Brownie', '2015': 72.4, '2016': 53.9, '2017': 39.1}
]
}
