To create a sparkline, use the setSparkline method to set the sparkline for a cell. You can use the getSparkline method to get the sparkline. For example:
There are three types of sparklines. The SparklineType enumeration represents the sparkline type.
line
column
winloss
You can use all three sparklines above in Excel. But for the other sparklines, such as Compatible sparkline, are not supported in Excel unless you get an add-in extension which provides that support.
If you want to remove the sparkline, use the removeSparkline method to remove the sparkline for the specified cell. For example:
You also can use formula to create a sparkline, please see Compatible for details.
The sparkline data and dateAxis also support a custom name. For example:
