パターンまたはグラデーション効果をセルに適用することにより、スプレッドシートのセルの外観を向上させることができます。
この機能を使用することで、ワークシートの選択したセルに強調を追加できます。また、白黒印刷を行う場合は、テキストを含むセルに単純なパターンを追加して、テキストを読みやすくすることもできます。
Style オブジェクトの BackColor プロパティを使用して、セルにパターン塗りつぶし効果を適用できます。また、パターン塗りつぶし効果に対してパターンスタイル、セルの背景色、およびパターン色を指定できます。
次の図は、スプレッドシートのセルにパターン塗りつぶしを使用する例を示します。
次のサンプルコードは、ワークシートのセル範囲にパターン塗りつぶし効果を適用します。
$(document).ready(function () {
// Spreadを初期化します。
var spread = new GC.Spread.Sheets.Workbook(document.getElementById('ss'), { sheetCount: 1 });
// アクティブシートを取得します。
var activeSheet = spread.getSheet(0);
// パターン塗りつぶしでセルのスタイルを設定します。
for (i = 1; i < 19; i++) {
var pat = { type: i, backgroundColor: "blue", patternColor: "red" };
style = new GC.Spread.Sheets.Style();
style.backColor = pat;
activeSheet.setStyle(i, 1, style)
}
グラデーション塗りつぶしは、異なる色間でブレンドを作成します。 Style オブジェクトの BackColor プロパティを使用して、セルにグラデーション塗りつぶし効果を適用できます。このプロパティを使用して、セルのグラデーションパス塗りつぶしスタイルまたはグラデーション塗りつぶしスタイルを指定できます。
次の図は、スプレッドシートのセルにグラデーション塗りつぶしを使用する例を示します。
次のサンプルコードは、ワークシートのセル範囲にグラデーション塗りつぶし効果を適用します。
$(document).ready(function () {
// Spreadを初期化します。
var spread = new GC.Spread.Sheets.Workbook(document.getElementById('ss'), { sheetCount: 1 });
// アクティブシートを取得します。
var activeSheet = spread.getSheet(0);
// グラデーション塗りつぶしでセルのスタイルを設定します。
var gra = { degree: 315, stops: [{ position: 0, color: "red" }, { position: 0.5, color: "white" }, { position: 1, color: "blue" },] };
style = new GC.Spread.Sheets.Style();
style.backColor = gra;
activeSheet.setStyle(1, 1, style);
// グラデーションパス塗りつぶしでセルのスタイルを設定します。
var gra2 = { type: "path", left: 0.4, top: 0.4, right: 0.6, bottom: 0.6, stops: [{ position: 0, color: "black" }, { position: 0.5, color: "blue" }, { position: 1, color: "white" },] },
style = new GC.Spread.Sheets.Style();
style.backColor = gra2;
activeSheet.setStyle(1, 3, style)
}
たとえば、イタリアの都市の地域ごとの人口のデータを表示したいとします。ここでは、パターン塗りつぶしとグラデーション塗りつぶしの効果を使用して、セルを強調することができます。グラデーションパス塗りつぶしスタイルを使用して、「都市」、「人口」、「地域」のヘッダのデータを強調表示できます。平均値を超える母集団データはグラデーション塗りつぶしスタイルを使用して強調表示され、平均値を下回る地域データはパターン塗りつぶしスタイルを使用して強調表示されます。
次の図は、セルにパターン塗りつぶしとグラデーション塗りつぶしの効果を使用する例を示します。
次のサンプルコードは、ワークシートのセルにパターン塗りつぶしとグラデーション塗りつぶしの効果を適用します。
$(document).ready(function () {
