Their main purpose is to present comparisons between different sets of data, such as the scores of different students with and without preparation or the nominal external debt and its percentage compared to the GDP. Making a double bar graph on the computer is an easy task, as all you need is spreadsheet software, such as Microsoft Excel or OpenOffice.org Calc.
