SYNOPSIS
subroutine grid(xpage,ypage,deltax,deltay,nxsp,nysp)
real,intent(in) :: xpage, ypage real,intent(in) :: deltax, deltay integer,intent(in) :: nxsp, nysp
DESCRIPTION
GRID(3f) draws a linear grid.
OPTIONS
XPAGE,YPAGE are the coordinates, in inches, of the lower left corner of the grid DELTAX is the number of inches between grid lines in the X direction. DELTAY is the number of inches between grid lines in the Y direction. NXSP,NYSP are the number of grid intervals in the X and Y directions, respectively. The number of grid lines is one more than the number of grid intervals.
COMMENTS
GRID generates a linear grid of any size. The number of lines drawn is NXSP+1 in the X direction and NYSP+1 in the Y direction.
EXAMPLE
Sample program:
program demo_grid use M_calcomp, only : plots, plot, newpen, grid use M_calcomp, only : END implicit none real :: xmax=8.5,ymax=11.0 real :: step call plots(0.0,xmax,0.0,ymax) ! make a 8 1/2 x 11 inch page call newpen(1) ! red step=0.25 ! make 1/4 inch grid call grid(0.0,0.0,step,step,int(xmax/step)+1,int(ymax/step)+1) call newpen(2) ! green step=0.50 ! make 1/2 inch grid call grid(0.0,0.0,step,step,int(xmax/step)+1,int(ymax/step)+1) call plot(0.0,0.0,END) ! end graphics end program demo_grid
