Represents the high-low lines in a chart group.
Assembly: Microsoft.Office.Interop.PowerPoint (in Microsoft.Office.Interop.PowerPoint.dll)
High-low lines connect the highest point with the lowest point in every category in the chart group. Only 2-D line groups can have high-low lines. This object is not a collection. There is no object that represents a single high-low line; you either enable high-low lines for all points in a chart group or disable them.
If the HasHiLoLines property is false, most properties of the object are disabled.
