Linux Graphics Software: Color Rectangular Cells Freely

[Milentije]

I have problem like this:recetengular cells,each of the cells should be colored.I have tried with NCL-NcCAR but it is too complicated to write script for me and I do not want to waste time.Can anyone tell me about free software?

A quick and dirty solution might be to use OpenOffice Calc and set the cell background color as a function of the data in the cell.

Thanks,but I prefer something more maths related,like I give input data and get image.
