ChartBorder Object (PowerPoint)
Represents the border of an object.
Version Information
Version Added: PowerPoint 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
Note
Although the following code applies to Microsoft Word, you can readily modify it to apply to PowerPoint.
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
