値が小さいローソク足を表示しようとしていますが、チャートにろうそくが表示されません。

次に例を示します。

parseFloat（）を使用して、Ask/High値の文字列を数値に変更する必要があります。

data.push([
         parseInt(jsonData[i].InserTime.substr(6)),
         parseFloat(jsonData[i].Ask),
         parseFloat(jsonData[i].High),
         parseFloat(jsonData[i].Low),
         parseFloat(jsonData[i].Bid)]);
