年スパークラインを作成するには、数式内でYearSparkline関数を使用します。=YEARSPARKLINE(year, dataRange, emptyColor, startColor, middleColor, endColor)または=YEARSPARKLINE(year, dataRange, colorRange)となります。
この関数には、以下のパラメータを指定できます。
year : 4桁の年数（「2015」など）
dataRange : 最初の列が日付であり、次の列が数値となる範囲を表す参照（「A1:B400」など）
emptyColor : 値のない日、またはゼロ値の日を表す色文字列（「lightgray」など）
startColor : 最小値に当たる日を表す色文字列（「lightgreen」など）
middleColor : 最小値と最大値の平均値に当たる日を表す色文字列（「green」など）
endColor : 最大値に当たる日を表す色文字列（「darkgreen」など）
colorRange : データが色文字列となる範囲を表す参照
