gnuplot - no space between graph and png image edge
How to create a .png image in `gnuplot` to see no spaces between graph itself and image edges.
I use

    set terminal pngcairo size 800,600 enhanced 

I want exactly 800x600 image. And want all 0X axis correspond to [0..800] interval, and all 0Y correspond to [0..600] interval.
