Examples

Ex.1: Cutting a grid crossing x axis

win demo          ;# Get demo window (450000 460000 6450000 6460000 1000 4000)
spe bgc whi       ;# Specify background color to white
mak ran 11        ;# Make 11 random points
grp 222 222       ;# Make grid of dimension 222 x 222
map               ;# Map the grid
ctp x 453000      ;# Cut the grid crossing x axis at 453000
col bla           ;# Black color
pol 2             ;# Draw cut line with line width 2
