OpenOffice Calc is the most powerful and widespread open source spreadsheet application in existence. It is the only real alternative to Excel.<strong>Jacek Artymiak</strong> is widely regarded as the authority on OpenOffice Calc.&nbsp;He takes you, step by step, from the&nbsp;interface and handling Calc files to working with data sources small and large.&nbsp;Artymiak then extends&nbsp;the reader's skillset to data visualization, writing&nbsp;complex formulas and performing statistical analysis. <em>Beginning OpenOffice Calc</em> allows you to gain confidence in the considered use of statistical&nbsp;formulas, but does not&nbsp;assume familiarity with another spreadsheet application.
