基本应用

迷你图在显示 SpreadJS 数据的趋势时非常有用,特别是当你与其他人共享数据时。 使用迷你图(单个工作表单元格内的微型图表)可以直观地表示和显示数据趋势。 迷你图可以通过不同颜色吸引对某些内容(如季节性增加或降低或经济周期)的注意,并突出显示最大和最小值。

你可以使用 setSparkline 方法来给某个单元格设置迷你图。 并使用 getSparkline 方法来获取迷你图。例如: SpreadJS 支持 3 种迷你图. SparklineType 枚举表示了各种迷你图的类型: line column winloss 您可以在Excel中使用上面的所有三个sparklines。但是对于其他的sparklines,比如Compatible sparkline, Excel中不支持,除非您得到一个提供这种支持的外接程序扩展。 你可以使用 removeSparkline 方法来移除指定单元格的迷你图。例如: 你也可以使用公式来创建迷你图, 参见 Compatible. 迷你图 data 和 dateAxis 也支持自定义名称。例如:
var spreadNS = GC.Spread.Sheets; window.onload = function () { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); }; function initSpread(spread) { var sheet = spread.getSheet(0); sheet.suspendPaint(); sheet.options.allowCellOverflow = true; var data = [1,-2,-1,6,4,-4,3,8]; var dateAxis = [new Date(2011, 0, 5),new Date(2011, 0, 1),new Date(2011, 1, 11),new Date(2011, 2, 1), new Date(2011, 1, 1),new Date(2011, 1, 3),new Date(2011, 2, 6),new Date(2011, 1, 19)]; sheet.setValue(0, 0, "Series 1"); sheet.setValue(0, 1, "Series 2"); for(let i=0;i<8;i++) { sheet.setValue(i+1, 0,data[i]); sheet.getCell(i+1, 1).value(dateAxis[i]).formatter("yyyy-mm-dd"); } sheet.setColumnWidth(1,100);
