使用例:集計スライサー

GeneralSlicerDataのaggregateDataメソッドを使用すると、特定の行や列のデータを集計できます。

<p><strong>aggregateData(columnName: string, aggregateType: SlicerAggregateType, range?: ISlicerRangeConditional): number</strong></p> <p><strong>SlicerAggregateType</strong>に用意された以下の集計方法が選択可能です。</p> <ul> <li><strong>AVERAGE</strong></li> <li><strong>COUNT</strong></li> <li><strong>COUNTA</strong></li> <li><strong>MAX</strong></li> <li><strong>MIN</strong></li> <li><strong>PRODUCT</strong></li> <li><strong>STDEV</strong></li> <li><strong>STDEVP</strong></li> <li><strong>SUBTOTAL</strong></li> <li><strong>SUM</strong></li> <li><strong>VARS</strong></li> <li><strong>VARP</strong></li> </ul> <p>また、本ページの右側に示されるように、独自のデータ集計機能を作成することもできます。</p>
