- Start the program from the Windows Start/Program Files/GGEbiplot if you have GGEbiplot installed. If not, double-click the executable file GGEbiplot.exe or its shortcut.
- Once started, a window with three buttons, namely, Start, Exit, and Help, will appear:
- Click the Start button. Another window, the Spreadsheet window, will appear with the following buttons: Open Data (*.*), Open Data (*.csv), Biplot Analysis, Close, and Exit.
- If your data is of Excel or Access format
- Click Open Data (*.*), and an Open File dialog will appear for you to select a file.
- If the file contains only one table, the table will be opened directly on the Spreadsheet; otherwise you will be prompted to select a table from the list box on the top-left of the Spreadsheet window.
- The data sheet will be opened:
NOTE: This dataset is used extensively in this manual to demonstrate various functions of GGEbiplot. You could go back to this table to verify the interpretations based on the biplot are accurate.
A biplot based on the data will show on the screen in one or a few seconds, depending on the dataset size.
If your data is of "*.csv":
- Click the Open Data (*.csv) button. A message box will appear to guide you to open a csv file from the Biplot window, which will appear when you close the message box.
- Click the File...Open a text data file, and an Open File dialog will appear for you to select a file.
Comments: You will find it surprisingly fast to generate a well labeled, nice-looking, publication quality, fully functional biplot using GGEbiplot; much faster than any other available methods. Furthermore, generating a biplot is just the beginning, rather than the end, of biplot analysis. This is the more compelling reason why you need GGEbiplot for biplot analysis. My estimation is, and I think your experience will confirm, that using the GGEbiplot is one million times more efficient than using a good SAS macro in terms of both biplot construction and analysis.
