箱ひげ図

箱ひげ図は、データの分散を四分位数で表示します。箱に、垂直の線（ひげ）を追加する場合もあります。この線は、上位四分位点と下位四分位点の範囲外のばらつきを示します。ひげの外側にある点は、外れ値です。箱ひげ図は通常、統計解析に用いられます。

BoxWhiskerSeries、ClusteredBoxWhiskerSeries、およびYPlotAreaクラスを使用して、次の図に示すように、複数の系列から成る箱ひげ図を作成します。

チャートデザイナを使用したチャートの作成については、「チャートデザイナ」を参照してください。

設定方法

シートにデータを設定します。
シートのAddChartメソッドを使用して、1.のデータを参照するチャートを追加します。
