谷歌可视化数据格式(Google Visualization Data Format,简称GVF)是一种用于描述表格数据的JSON格式。它被广泛用于谷歌图表(Google Charts)库中,以便在网页上创建交互式图表和图形。
GVF数据通常包括以下几种类型:
GVF广泛应用于各种需要数据可视化的场景,例如:
以下是一个简单的GVF数据示例:
{
"cols": [
{"id":"string","label":"Name","pattern":"","type":"string"},
{"id":"number","label":"Salary","pattern":"","type":"number"},
{"id":"boolean","label":"Full Time","pattern":"","type":"boolean"}
],
"rows": [
{"c":[{"v":"John"},{"v":50000},{"v":true}]},
{"c":[{"v":"Jane"},{"v":60000},{"v":false}]},
{"c":[{"v":"Bob"},{"v":70000},{"v":true}]}
]
}
原因:
解决方法:
cols
和rows
部分的结构。假设原始数据如下:
{
"cols": [
{"id":"name","label":"Name","type":"string"},
{"id":"salary","label":"Salary","type":"number"},
{"id":"fulltime","label":"Full Time","type":"boolean"}
],
"rows": [
{"c":[{"v":"John"},{"v":50000},{"v":true}]},
{"c":[{"v":"Jane"},{"v":60000},{"v":false}]},
{"c":[{"v":"Bob"},{"v":70000},{"v":true}]}
]
}
修正后的数据:
{
"cols": [
{"id":"name","label":"Name","type":"string"},
{"id":"salary","label":"Salary","type":"number"},
{"id":"fulltime","label":"Full Time","type":"boolean"}
],
"rows": [
{"c":[{"v":"John"},{"v":50000},{"v":true}]},
{"c":[{"v":"Jane"},{"v":60000},{"v":false}]},
{"c":[{"v":"Bob"},{"v":70000},{"v":true}]}
]
}
通过确保cols
和rows
部分的结构正确,并且数据类型匹配,可以解决数据无法正确显示的问题。
