スパークラインのチャートには、マーカーやデータ点を表示できます。 スパークラインの頂点(山)、頂点(谷)、負のポイント、始点、終点に、それぞれ異なる色を指定できます。
頂点(山)は、最大値を表すポイントです。 頂点(谷)は、最小値を表すポイントです。 負のポイントは、負数の値を表します。 始点は、チャート上に最初に描画されるポイントです。 終点は、チャート上に最後に描画されるポイントです。
options.markersColor プロパティは、折れ線スパークラインのみに適用されます。折れ線、縦棒、および勝敗スパークラインの数式には、マーカーを設定するための各種オプションを使用できます。
次のサンプルコードは、スパークラインを追加して、各マーカーの色を指定します。
