This might get you started - note that your label field (#1) contains a space so it's best to use tab for field separator.

Code:
#!/usr/bin/gnuplot

set terminal png size 1024,768
set output 'graph.png'
set title "System monitoring"

set style data histogram
set style histogram cluster gap 1
set style fill solid border -1
set boxwidth 0.75 
set xtic scale 0
set key outside

set ylabel "MB"
set key left
set datafile separator "\t"

plot 'datafile' using ($2/1e6):xtic(1) title "Memory" fc rgb '#99ffff', \
     'datafile' using ($3/1e6)         title "Buffer" fc rgb '#4671d5', \
     'datafile' using ($4/1e6)         title "Cache"  fc rgb '#06d075', \
     'datafile' using ($5/1e6)         title "Free"   fc rgb '#4f4f4f'

Chubler_XL thank you for the excellent grpah . It works.

Instead of bars can we also have a wave graph

You can have whatever you want. Gnuplot has thousands of options, see examples here. Fiddle until you find the combination you want.
