I'm looking to make a 4 coordinate paper plot in Matlab. I have not seen this done before, but I'm assuming there is a way it can be done. Has anyone ever successfully made one? I've done quite a bit of searching and have not found anything. If you're not sure what a 4CP plot looks like, check the link below and look at Figure 4. As a side note, it's used to make a Pseudo-Velocity Shock Spectrum (PVSS) in structural dynamics where the displacement, velocity, and acceleration asymptotes are represented per frequency. Thanks for your help.
