Walls

A wall is the area (or plane) behind, below, or to the side of a chart.

壁面

A wall can have a border, fill effect, or width (measured in model units). The wall can be visible or hidden. The axis grids (major and minor) and stripes are painted on the walls. The axis grid lines (major and minor) are painted over the axis stripes.
