你可以通过 YearSparkline 方法创建一个年份迷你图：=YEARSPARKLINE(year, dataRange, emptyColor, startColor, middleColor, endColor) 或者 =YEARSPARKLINE(year, dataRange, colorRange)。
此函数有以下参数：
year : 类型为数字，表示年份，比如 2015。
dataRange : 类型为引用，所引用的单元格第一列为日期，第二列为数字，比如 "A1:B400"。
emptyColor : 类型为颜色字符串，用这种颜色填充没有值或者值为0的日期，比如 "lightgray"。
startColor : 类型为颜色字符串，用这种颜色填充值最小的日期，比如 "lightgreen"。
middleColor : 类型为颜色字符串，用这种颜色填充值为最大值和最小值平均值的日期，比如 "green"。
endColor : 类型为颜色字符串，用这种颜色填充值最大的日期，比如 "darkgreen"。
colorRange : 类型为引用，所引用的单元格数据为颜色字符串。
