File g Open data set (ctrl-O)

This opens a data file for displaying. A dialog box opens where you can select the files you want to open.

In the upper window you can select the files, and by clicking “Add” they appear in the lower window. The files in the lower window are the ones that will actually be opened. This way, you can even select files across multiple folders and put them in the lower window before opening them. After clicking “OK” all the files will be opened and displayed. 

In the application subfolder “TestSpectra” you can find a few sample data files which you can use to test the program.

NOTE ON FILE FORMAT:

The program assumes by default that the measure file is a text file which consists of one or two columns of data. After opening, Spectrum Viewer determines by itself the number of columns that the file has. With one column it numbers the X of every consecutive data point from one to the number of data points in the file, while storing the data value in the Y axis. With two columns, the left column becomes the X axis, and the right column becomes the Y axis. If you would like it the other way around: swapping axes after loading is very easy, just select all sets by pressing ctrl-A and give a Swap X and Y axis command. Or, you can set the X and Y columns manually with the Open special format command.

If your file has more than two columns, you have to use the Open special format command.
