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);
sheet.setValue(11, 0, "*Data Range is A2-A9");
sheet.setValue(12, 0, "*Date axis range is B2-B9");
var dataRange = new spreadNS.Range(1, 0, 8, 1);
var dateAxisRange = new spreadNS.Range(1, 1, 8, 1);
