Represents major or minor gridlines on a chart axis.
Assembly: Microsoft.Office.Interop.PowerPoint (in Microsoft.Office.Interop.PowerPoint.dll)
Gridlines extend the tick marks on a chart axis to make it easier to see the values associated with the data markers. This object is not a collection. There is no object that represents a single gridline; you either enable all gridlines for an axis or disable all of them.
Use the MajorGridlines property to return the object that represents the major gridlines for the axis. Use the MinorGridlines property to return the object that represents the minor gridlines. It is possible to return both major and minor gridlines at the same time.
