drawing rectangles with gnuplot

[Gene Wagenbreth]

I want to draw rectangles with gnuplot. I dont want to plot anything.

I create a rectangle with:
set object 2 rect from -1,1 to 0,5 fc rgb "gold"

but to see the rectangle I have to plot something:
plot [-5:5] x lc rgb "white"

How do I get gnuplot to just draw the rectangles I have defined ?

Will gnuplot support hundreds of different rectangles ?

Is there a better way to do this ?

Thanks

You must plot something to get the rectangles, as you said.

Yes:

unset border
unset tics
do for [i=0:1000] {
x = 9*(rand(0)-0.5)
y = 9*(rand(0)-0.5)
set object rectangle from x, y to x+rand(0),y+rand(0) fc rgb "gold"
}
plot [-5:5] x lw 0 t ''
