Drawing dotted paper

### 26.2.2 Drawing dotted paper

The dot_paper command draws dotted paper.

- dot_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 dots.
  - yspacing, the spacing in the y direction.
  - Optionally, x=xmin..xmax, to determine how far the dots extend 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 dots extend in the y direction (by default, the distances given in the graphic configuration page accessible from the main menu).
- dot_paper(xspacing,θ,yspacing ⟨,x=xmin..xmax,y=ymin..ymax ⟩) draws dotted paper.

#### Example

axes=0; dot_paper(0.6,pi/2,0.6,display=grey)
