I would just like to expand upon the top answer  which uses GNUPlot to create a bar graph  for absolute beginners because I read the answer and was still confused from the deluge of syntax   We begin by writing a text file of GNUplot commands  Lets call it commands txt   set term png set output  graph png  set boxwidth 0 5 set style fill solid plot  data dat  using 1 3 xtic 2  with boxes   set term png will set GNUplot to output a  png file and set output  graph png  is the name of the file it will output to   The next two lines are rather self explanatory  The fifth line contains a lot of syntax    plot  data dat  using 1 3 xtic 2  with boxes    data dat  is the data file we are operating on  1 3 indicates we will be using column 1 of data dat for the x-coordinates and column 3 of data dat for the y-coordinates  xtic   is a function that is responsible for numbering labeling the x-axis  xtic 2   therefore  indicates that we will be using column 2 of data dat for labels     data dat  looks like this   0 label       100 1 label2      450 2  bar label  75   To plot the graph  enter gnuplot commands txt in terminal

Simple bar graph     set boxwidth 0 5 set style fill solid plot  data dat  using 1 3 xtic 2  with boxes   data dat   0 label       100 1 label2      450 2  bar label  75   If you want to style your bars differently  you can do something like     set style line 1 lc rgb  red  set style line 2 lc rgb  blue   set style fill solid set boxwidth 0 5  plot  data dat  every   0  0 using 1 3 xtic 2  with boxes ls 1          data dat  every   1  2 using 1 3 xtic 2  with boxes ls 2   If you want to do multiple bars for each entry   data dat   0     5 0 5   6   1 5   3 2     7   3     8 3 5   1   gnuplot   set xtics   label  0 25   label2  1 75   bar label  3 25    set boxwidth 0 5 set style fill solid  plot  data dat  every 2    using 1 2 with boxes ls 1         data dat  every 2  1 using 1 2 with boxes ls 2     If you want to be tricky and use some neat gnuplot tricks   Gnuplot has psuedo-columns that can be used as the index to color   plot  data dat  using 1 2 0 with boxes lc variable     Further you can use a function to pick the colors you want   mycolor x      x 11244898    2851770  plot  data dat  using 1 2  mycolor  0   with boxes lc rgb variable     Note  you will have to add a couple other basic commands to get the same effect as the sample images
