grAxis objects in Graph controls
The Frame property specifies the line style used in the frame for an axis of a 3D Graph. The frame is the side of the 3D box associated with the selected axis.
To set the Frame line style of an Axis:
Select a 3D graph style on the General page of the graph control’s Properties view. Not all 3D graph styles support the Frame property.
Display the Axis tab page of the Properties view and select the desired axis from the Axis drop-down list.
Select the desired line style from the Frame drop-down list in the Line Style group.
The Frame property takes a value of the LineStyle enumerated datatype.
This example specifies a dashed line for the Series axis frame of Graph gr_1:
gr_1.Series.Frame = Dash!
