株価チャート

株価チャートは、データの変動を図示する目的で、広く使用されます。株価チャートでは、株価だけでなく、日々の降雨量や年間気温などの変動も表すことができます。一般的には、財務データの分析や、株価情報の視覚化に適したチャートです。

株価チャートには、ワークシートの列または行ごとにまとめたデータをプロットできます。

Spread.Sheetsでは、以下の種類の株価チャートがサポートされます。以下の例では、特定期間ごとの市場データ分析情報を、各種の株価チャートで表します。

  1. 高値-安値-終値

    「高値-安値-終値」を表す株価チャートは、1)高値、2)安値、3)終値の順にデータ値を表します。高値と安値を結ぶ線の間に、終値が示されます。

    次に、株価チャート(高値-安値-終値)の例を示します。



  2. 始値-高値-安値-終値

    「始値-高値-安値-終値」を表す株価チャートは、1)始値、2)高値、3)安値、4)終値の順にデータ値を表します。

    次に、株価チャート(始値-高値-安値-終値)の例を示します。



  3. 出来高-高値-安値-終値

    「出来高-高値-安値-終値」を表す株価チャートは、1)出来高、2)高値、3)安値、4)終値の順にデータ値を表します。

    次に、株価チャート(出来高-高値-安値-終値)の例を示します。



  4. 出来高- 始値-高値-安値-終値

    「出来高-始値-高値-安値-終値」を表す株価チャートは、1)出来高、2)始値、3)高値、4)安値、5)終値の順にデータ値を表します。

    次に、株価チャート(出来高-始値-高値-安値-終値)の例を示します。
