Hello,
I want to make a PCA analysis with data based on spectra. The PCA is working fine and I also receive nice results. The problem is that my Loadingplot is totally overcrowded because I have around 3500 variables. It would be so much better to display the Loadingplot as a spectrum instead of vectors (in this case the x-axis in the loadingplot shall represent the wavenumber and the y-axis the loading on one PCA).
My data is sorted like in the table below with the difference that I have more than 5 variables and more than 3 samples 
| Title/ wavelength | 100 | 101 | 102 | 103 | 104..... |
|---|
| Sample A | | | | | |
| Sample B | | | | | |
| Sample C | | | | | |
It would be even better if it is also possible to do that with mass spectra. In this case it would be really nice if the data could be sorted after m/z@a certain time. So that 2 information are grouped together. if possible. M/z is in one column and time in another (in the raw data).
Greetings!
