Most terminals now allow you to set an explicit background color for the plot. The special linetype ‘bgnd‘ will draw in this color, and ‘bgnd‘ is also recognized as a color. Examples:

         # This will erase a section of the canvas by writing over it in the
         # background color
         set term wxt background rgb "gray75"
         set object 1 rectangle from x0,y0 to x1,y1 fillstyle solid fillcolor bgnd
         # This will draw an "invisible" line along the x axis
         plot 0 lt bgnd
