如果位置包含空，我想在下面的格式中考虑 0。假设数据的 total_views 值。
this.geographySeriesData = [
name: 'India',
data: [500, 555, 444, 777, 877, 9944, 750],
,
name: 'USA',
data: [10, 1000, 1200, 1000, 1200, 1000, 500],
];
【问题讨论】：
您是否已经尝试过？很高兴已经在这里直接向我们提供您的一些试验 【参考方案1】：您可以使用此代码进行转换。这不是最佳的，但非常简单易懂。您需要的数据存储在 finalResult 变量中。
const result = ;
const locations = data.map(el => el.location).flat();
locations.forEach(loc =>
result[loc.country] = [];
);
locations.forEach(loc =>
result[loc.country].push(loc.total_views);
);
const finalResult = Object.keys(result).map(key => ( name: key, data: result[key]));
【讨论】：
【参考方案2】：你可以像这样实现精确的格式
countryList = []
countryObject =
data.forEach((d) =>
d.location.forEach((loc) =>
if(loc.country in countryObject)
countryViewsList = countryObject[loc.country]
countryViewsList.push(loc.total_views)
countryObject[loc.country] = countryViewsList
else
countryObject = Object.assign(countryObject, [loc.country]: [loc.total_views])
)
)
Object.keys(countryObject).forEach((k)=>
countryList.push(
name: k,
data: countryObject[k]
)
)
countryList 正是您要求的格式。
