plotting filled rectangle at given coordinated

[sche...@gmail.com]

hi,

I am new to gnuplot, and I couldn't find it in the docs in reasonable
time..
I need to plot a few rectangles using their vertex coordinates. The
rectangles may overlap.
For example (start denoted upper left corner, end - lower right
corner):
rect1: x_start=10 y_start=20 x_end=100 y_end=100
rect2: x_start=20 y_start=40 x_end=80 y_end=70
....
I can have file with these numbers in any needed format.

what is the simplest way to do it with gnuplot?

thanks,
Stas

set obj rect from 10,20 to 100,100 fc rgb 'red'
set obj rect from 20,40 to 80,70 fc rgb 'green'

Use "help set obj" for more info.

Cheers + HTH,

- Joerg

Joerg, Ethan,

thanks for your help!
On my system there was gnuplot 4.0 which didn't have such object...

thanks again,
Stas
