Hello,
When I do the FRF analysis and visualize the responses in Hypergraph they appear as magnitude and phase, how can I get these answers in rectangular coordinates (real and imaginary) directly?

    In below post i shared tutorial for plotting complex results.

     

    Once a Complex Plot has been created, you still have the  option to switch whether you are plotting phase/magnitude or real/imaginary. 

    In the example , the plot is created first and it contains phase/magnitude data.  

    By right clicking in the Graphics Area and selecting Switch to Real/Imaginary, the real/imaginary curves can be created. You can then switch back by selecting Switch to Phase/Magnitude.
