ChartBorder Object (Word)
Represents the border of an object.
Version Information
Version Added: Word 2007
Remarks
Most bordered objects have a border that is treated as a single entity, regardless of how many sides it has. The entire border must be returned as a unit. To return a Border object, use the Border property for the particular bordered object (for example, the Border property of a TrendLine object).
Example
The following example changes the type and line style of a trendline on the active chart.
With ActiveDocument.InlineShapes(1).Chart.SeriesCollection(1).Trendlines(1)
.Type = xlLinear
.Border.LineStyle = xlDash
End With
