Hey Felipe--
Two things come to mind. Firstly, did you make sure your columns are properly set to X, Y and Z? It might be that your data is fine but Origin is plotting it with Y values as X, etc.
Secondly, I noticed the two axes in the top graphic have the same label but different values. Was there some kind of unit conversion involved with this data?
Best regards,
