Default: | none
See: | ywall-border-color ywall-color floor-grid zwall-border-color zwall-color

What color, if any, to draw the "floor" of the graph (either where y=0 or y=min(y), depending on the value of xaxis-at-zero).
You can set the color and border color, or just set the border color for a grid on an otherwise transparent wall - although the grid can be modified with the XWALL-GRID attribute.

This draws black lines on a gray background
