The best approach to this problem is to break it down to basic steps:
- Read the two channels out of the TDMS file using the TDMS Read function.
- Construct a cluster out of the two resulting arrays with the Bundle function.
- Wire the resulting cluster to an XY Graph.

This way the two channels stored in a TDMS file will be plotted in XY mode.
