Open Photometry File

This command brings up the Photometry plot without analyzing new data. Instead, data is read from a Comma Separated Values (.CSV) file. This loads data into the Photometry tool.

Availability of this feature depends on Product Level.

The dialog box allows you to browse the computer disk and select a .CSV file. When you have selected the file, click Open to load it into the plot. The Discard All button is enabled only if data has already been loaded. Clicking Discard All erases all previous loaded data from the plot and returns to the Photometry plot. Otherwise, the new data will be loaded on top of the old data.

Data can be combined into a single plot from multiple files only if the same type of abscissa ("time") information is used in all of them, otherwise an error is reported. When the abscissa is a sequence number, you can set Offset sequence numbers by to an arbitrary integer; this value is added to the newly imported data to distinguish it from data loaded earlier, or analyzed in the current Photometry session. Typically, the offset should increase from one file to the next by the number of measurements in the earlier file. Alternatively, to load a sequence-numbered file immediately to the left of the current data, set the offset to the negative of the number of points in the file being loaded.
