app里折线图报错：Cannot create property 'formatter' on number '35'

这是我传入的数据：
//模拟服务器返回数据，如果数据格式和标准格式不同，需自行按下面的格式拼接
let res = {
categories: ["2018", "2019", "2020", "2021", "2022", "2023"],
series: [{
name: "成交量A",
data: [35, 8, 25, 37, 4, 20]
},
{
name: "成交量B",
data: [70, 40, 65, 100, 44, 68]
},
{
name: "成交量C",
data: [100, 80, 95, 150, 112, 132]
}
]
};
