轉換字符串值爲int被highchart

內使用在該小提琴IM試圖JSON字符串解析和圖表上Y軸的結果：轉換字符串值爲int被highchart

但Y值不被映射到其json值。

我正在使用parseInt(obj.in)將json字符串轉換爲int值。但這似乎是正確的？

你的數據陣列邏輯看起來好像沒什麼問題，並登錄正確的值控制檯，你確定你正在配置你的圖表和系列？ – timothyclifford

我不知道主要問題，但至少，'parseInt（obj.in）'應該是'parseInt（obj.in，10）' – ben

的問題是要創建dataArray所有X & Y值的平面數組。當您將數據添加到highcharts，它預計X & Y值是嵌套數組類似：

[[1,123], [2,234], [3,345]]

試試這個：

dataArray.push([Date.parse(d), parseInt(obj.in)])
