SpreadJSでは、集合縦棒グラフ、積み上げ縦棒グラフ、および100%積み上げ縦棒グラフがサポートされます。チャートの種類を取得するには、GC.Spread.Sheets.Charts.ChartType.columnClusteredプロパティを使用します。
たとえば、このチャートAPIを使用することで、集合縦棒グラフ（columnClustered）を挿入したり、チャートのスタイルを変更したりできます。
columnStackedおよびcolumnStacked100を使用すると、縦棒グラフを通常の積み上げグラフ、または100%積み上げグラフに設定できます。
積み上げ縦棒グラフ（columnStacked）は、系列を垂直方向に積み上げて表示します。
100%積み上げ縦棒グラフ（ColumnStacked100）は、系列を垂直方向に積み上げ、すべて100%となるように値を均一化します。
