Select Options® 3D options to call up the 3D Options dialog window.
The Row/column lines option displays grid lines separating the rows and columns in a 3D graph. These lines appear on the base of the graph and extend vertically up the back walls.
The Row/column lines option has no effect on scale lines extending horizontally across the back walls of the 3D frame.
You can set the color for the row/column lines by setting the 3D Row/column lines variable in the Color Assignment menu.
This option only applies fully to the Towers and Pyramids graph types. For Walls and Wedges, row/column lines appear on the floor of the 3D frame, but not on the back walls.
