### 26.2.4 Drawing grid paper

The grid_paper command draws grid paper.

- grid_paper takes three mandatory arguments and two optional arguments.
  - xspacing, the spacing in the x direction.
  - θ, the angle from the horizontal to draw the grid.
  - yspacing, the spacing in the y direction.
  - Optionally, x=xmin..xmax, to determine how far the grid extends in the x direction (by default, the distances given in the graphic configuration page accessible from the main menu).
  - Optionally, y=ymin..ymax, to determine how far the grid extends in the y direction (by default, the distances given in the graphic configuration page accessible from the main menu).
- grid_paper(xspacing,θ,yspacing⟨,x=xmin..xmax,y=ymin..ymax⟩) draws grid paper.

#### Example

axes=0; grid_paper(1,pi/2,1,display=grey)
