FFT Analysis on multiple "runs"
Using DEWESoft X3 SP4, I am looking to record data from an accelerometer while performing a vehicle speed sweep. Ideally, a total of 5 speed sweeps would be performed, outputting 5 different data sets. I was wondering if there was a way to overlay all 5 data sets on the same FFT plot either by
1) Analyze multiple files on the same FFT plot (ie Data_001, Data_002, Data_003, etc) or
2) Setup the file to overlay "runs" on the same FFT plot (all data can be stored in the same file, if needed, or can be stored as a multifile)
Thanks in advance for your help.

you can open the first data file in analysis and then use the import function to import the relevant channels:
Here you can add multiple files at once:
Then select the channels you want to import and click the "Import channels" button to import them:
After the channels have been imported, you can graph them all at once on a single graph:
I hope this helps.
Thank you Aljaž for the quick and helpful response! I do have one more follow up question.
On the FFT plots, I know you can add the max peak values by using the max marker option.
Is there a way to save these values as a math/input channel so they can be used to create a new, separate plot?
