  We present measurements of bias triangles in several biasing configurations.
Thorough analysis of the data allows us to present data from all four possible
bias configurations on a single plot in chemical potential space. This
presentation allows comparison between different biasing directions to be made
in a clean and straightforward manner. Our analysis and presentation will prove
useful in demonstrations of Pauli-spin blockade where comparisons between
different biasing directions are paramount. The long term stability of the CMOS
compatible Si/SiO2 only architecture leads to the success of this analysis. We
also propose a simple variation to this analysis that will extend its use to
systems lacking the long term stability of these devices.
