I am not sure I understand your question.
You can right-click on the chromatogram graph and choose "Copy Data" and then paste that into a program such as Microsoft Excel.
Then, you could make a X-Y scatter plot of the data in Excel.
You can also export the chromatogram data using the Document Grid.
The columns with the chromatogram data are "Proteins > Peptides > Precursors > Transitions > Transition Results > Chromatogram > Raw Data"
If you want to learn more about the Document Grid you should look at the Custom Reports tutorial:
