React チャートのオーバーレイ
React IgrDataChart を使用すると、IgrValueOverlay を使用して定義した単一の数値で水平線または垂直線を配置できます。特定のシリーズの平均値や中央値などのデータを視覚化するのに役立ちます。
React 値オーバーレイの例
次の例は、いくつかの水平値オーバーレイがプロットされた縦棒チャートを示しています。

React 値オーバーレイのプロパティ
データバインディングに DataSource を使用する他のシリーズ タイプとは異なり、値オーバーレイは ValueMemberPath プロパティを使用して単一の数値をバインドします。さらに、値オーバーレイでは、使用する単一の axis を定義する必要があります。X 軸を使用する場合、値のオーバーレイは垂直線になり、Y 軸を使用する場合は、水平線になります。
数値の X 軸または Y 軸を使用する場合、ValueMemberPath プロパティは、値のオーバーレイを描画する軸上の実際の数値を反映する必要があります。カテゴリ X または Y 軸を使用する場合、ValueMemberPath は、値オーバーレイを表示するカテゴリのインデックスを反映する必要があります。
数値オーバーレイを角度角軸で使用すると、チャートの中心からの線として表示され、半径半径軸を使用すると、円として表示されます。
IgrValueOverlay 外観プロパティは、IgrSeries から継承されているため、例えば brush と thickness を使用でき、他のタイプのシリーズと同じように機能します。
IgrValueOverlay に軸注釈を表示して、所有する軸にオーバーレイの値を表示することもできます。これを示すために、isAxisAnnotationEnabled プロパティを true に設定できます。
React 値レイヤー
React チャート コンポーネントは、値の線を使用して、最小値、最大値、平均値などのデータのさまざまな焦点を示す機能も公開します。
IgrCategoryChart および IgrFinancialChart コンポーネントに IgrValueLayer を適用するには、チャート上で valueLines プロパティを設定します。このプロパティは、ValueLayerValueMode 列挙体のコレクションを受け取ります。複数の ValueLayerValueMode 列挙をチャートの valueLines コレクションに追加することで、同じチャート内で複数の値レイヤーを組み合わせたりできます。
IgrDataChart では、これは、チャートの IgrSeries コレクションに IgrValueLayer を追加し、次に valueMode プロパティを ValueLayerValueMode 列挙の 1 つに設定することによって行われます。これらの各列挙とその意味を以下に示します。
Auto:ValueLayerValueMode列挙体のデフォルト値モード。Average: 複数の値の線を適用して、チャートにプロットされた各系列の平均値を呼び出します。GlobalAverage: 単一の値線を適用して、チャート内のすべての系列値の平均を呼び出します。GlobalMaximum: 単一の値線を適用して、チャート内のすべての系列値の絶対最大値を呼び出します。GlobalMinimum: 単一の値線を適用して、チャート内のすべての系列値の絶対最小値を呼び出します。Maximum: チャートにプロットされた各系列の最大値を示すために、複数の値線を適用する可能性があります。Minimum: チャートにプロットされた各系列の最小値を示すために、複数の値線を適用する可能性があります。
IgrValueLayer 要素を使用するときに特定のシリーズが考慮されないようにする場合は、レイヤーに targetSeries プロパティを設定できます。これにより、レイヤーは定義したシリーズを強制的にターゲットにするようになります。単一の IgrDataChart 内に必要な数の IgrValueLayer 要素を含めることができます。
次のサンプルは、IgrCategoryChart 内のさまざまな valueLines の使用法を示しています。

React ファイナンシャル オーバーレイ
React 株価チャートに組み込みのファイナンシャル オーバーレイとインジケーターをプロットすることもできます。
チャート オーバーレイ テキスト (ベータ版)
React IgrValueOverlay、IgrValueLayer、およびすべてのデータ注釈レイヤーは、XamDataChart コンポーネントのプロット領域内にカスタム オーバーレイ テキストを描画できます。このオーバーレイ テキストを使用すると、レイヤーとの関係において、x 軸上の重要なイベント (例: 企業の四半期決算) または y 軸上の重要な値に注釈を付けることができます。
たとえば、DataAnnotationSliceLayer、IgrValueOverlay、IgrValueLayer を使用してオーバーレイ テキストを表示できます。
