File g Save data set / Save data set as
After manipulation you
can save a data set with its original name, or with a new name. A data set is
always saved as a text file with two columns, the X axis as the left column and
the Y axis as the right column.
File g Save all in one file
This can be used to save several data sets into one tab-separated, space-separated or comma-seperated ascii matrix file, or into one binary matrix file. When data sets are selected, only the selected sets will be saved. When no data sets are selected, all data sets will be saved, except the ones that are hidden.
The formats available are
YYYY: Discards all X data. Puts the Y array of the first selected set in the first column, and all the Y arrays of the following selected data sets in the following columns.
X YYYY: Puts the X array of the first selected set in the first column, the Y array of the first selected set in the 2nd column, and all the Y arrays of the following selected data sets in the following columns.
XY XY XY: Puts The X and Y array of the first selected set in the first two columns, the X and Y of the 2nd selected set in column 3 and 4, and so on.
Spectrum Viewer format (.svf). This binary format preserves several Spectrum Viewer specific data, like axis names. Mostly useful for programmers.
Note: instead of saving to a
file you can also copy the data into the clipboard and then paste it into
into another Windows program.
File g Save session (Shift-S)
This saves the state of the program into a Spectrum Viewer format file. After opening this file you will see the exact same view as when you saved it (axis names, hidden plots, selected plots, legend, zoom state, graph size etcetera). You would typically want to use this if you are using Spectrum Viewer to export graphs with legends for reports. If you save the session first and then load it with load session, your display will look exactly the same.
The difference between save session and "save all into one g Spectrum viewer format" is that with save session all data sets are saved, including those that are hidden. With save all into one only all selected data sets are saved.
