h2. Examples

h3. Ex.1: Line color map
{noformat:|borderWidth=1|bgColor=#eeeeee}
        # Digitize points and draw a b-spline
       
win demo      ;#  create the demo graphical window
    
   mak ran 11    ;#  make 11 random points
      
 grp 111 111   ;#  grid the points into 111 x 111 elements in rows and columns
       
lco n 11      ;#  display line colors
{noformat}
