系列は、チャートにプロットされるデータポイントの1セット(特定の行または列内の値)です。
Spread.Sheetsでは、1つのチャートを作成する場合に、1つまたは複数の系列をプロットできます。1つの系列は、1つの凡例項目によって表されます。チャートの系列コレクションに対しては、系列項目の取得、挿入、および削除を行えます。また、個々の系列の名前、枠線の幅や色、X値とY値、および塗りつぶし色もカスタマイズできます。このような系列の設定には、seriesメソッドおよびSeriesCollectionクラスを使用します。
次の図は、系列を設定した基本的なチャートを示します。
次の図は、様々な線スタイルを設定した基本的なチャートを示します。
次のコードは、チャートの系列を設定する方法を示します。
// 系列を設定します。
var series = chart.series();
var seriesItem = series.get(0);
seriesItem.yValues = "Sheet1!$B$5:$E$5";
seriesItem.backColor = "#d3d3d3";
seriesItem.border.width = 2;
series.set(0, seriesItem);
次のコードは、チャートで様々な線スタイルを設定する方法を示します。
// series(0)のlineTypeを設定します。
var series1 = chart.series().get(0);
series1.border.lineType = GC.Spread.Sheets.Charts.LineDashStyle.dashDotDot;
chart.series().set(0, series1);
// series(1)のlineTypeを設定します。
var series2 = chart.series().get(1);
series2.border.lineType = GC.Spread.Sheets.Charts.LineDashStyle.longDash;
chart.series().set(1, series2);
// series(2)のlineTypeを設定します。
var series3 = chart.series().get(2);
series3.border.lineType = GC.Spread.Sheets.Charts.LineDashStyle.sysDashDot;
chart.series().set(2, series3);
