Google Charts json日期格式

Question

我正在使用Google Charts並嘗試生成自己的JSON格式來呈現圖表，而不是使用庫。除了試圖弄清楚如何在json中表示日期格式以便Google圖表能夠理解...

規範： JSON不支持JavaScript日期值（例如「new Date（2008,1 ，28,0,31,26）「; API實現的確如此，但API現在支持以日期（年，月，日[，小時，分鐘，第二[，毫秒]），這裏的一切一天之後是可選的，月是零基礎

參考： https://developers.google.com/chart/interactive/docs/dev/implementing_data_source#jsondatatable

看完上面的規格似乎秈稻以日期格式（日期，年份，日期，月份）表示的日期格式可以工作，但這似乎不適用於我。

錯誤：

Uncaught Error: Type mismatch. Value Date(2012, 10, 3) does not match type date in column index 0 

JSON響應：我

{"type":"ComboChart","cols":[["date","Date"],["number","Overall"],["number","Current"],["number","Rating Count"]],"rows":[["Date(2012, 10, 3)",4.0,4.0,69],["Date(2012, 10, 4)",4.0,4.0,69]],"options":{"title":"Rating for FI","chartArea":{"width":"90%","height":"75%"},"hAxis":{"title":"Date"},"legend":"top","curveType":"none","pointSize":8,"seriesType":"bars","series":{"0":{"type":"bars","targetAxisIndex":0},"2":{"type":"line","targetAxisIndex":1}},"vAxes":{"0":{"title":"Rating","minValue":0,"maxValue":5},"1":{"title":"Rating Count"}}}} 

沒有什麼是跳出來，因爲這應遵循規範所要求的格式。我錯過了什麼？

你的語法是錯誤的，我認爲...... 你應該嘗試類似的東西：

{"type":"ComboChart","cols":[["date","Date"],["number","Overall"],["number","Current"],["number","Rating Count"]],"rows":[["Date(2012, 10, 3)"]],["Date(2012, 10, 4)"]],"options":{"title":"Rating for FI","chartArea":{"width":"90%","height":"75%"},"hAxis":{"title":"Date"},"legend":"top","curveType":"none","pointSize":8,"seriesType":"bars","series":{"0":{"type":"bars","targetAxisIndex":0},"2":{"type":"line","targetAxisIndex":1}},"vAxes":{"0":{"title":"Rating","minValue":0,"maxValue":5},"1":{"title":"Rating Count"}}}} 

對我來說，這個代碼工作：

{"c":[{"v":"Date(2012,11)"},{"v":6657}..... 

但這是更改月份，不是一天和使用JSON ....
