Gnumeric is a spreadsheet, a computer program used to manipulate and analyze numeric data. Gnumeric can help you keep track of information in lists, organize numeric values in columns and rows, perform and update complex calculations by defining each step of the calculation and modifying particular steps subsequently, create and display or print graphical plots of data using bar plots, line graphs, pie charts or radar charts, implement complex optimization modeling or perform many other tasks involving numbers, dates, times, names or other data.
The features of Gnumeric make it versatile and powerful. The screenshot (picture) of Gnumeric shown in Figure 1-1 demonstrates the main program window and some of the features currently available.
Using a spreadsheet generally involves several steps. First the application is started to obtain an empty workbook, which generally has several empty worksheets. Next, data and formulas are entered into one or several sheets. The data may be entered by hand or imported from external files. The formulas are generally entered by hand, possibly with the help of various tools. The data may be formatted to appear in particular ways and to clarify the structure of the data in the worksheet. A user may also create several graphical plots. Certain parts of the spreadsheets may be printed out as tables. The work is then usually saved into a file which can be re-opened later to add or modify the contents of the workbook.
