Polar plot in eigenfrequency analysis

Please login with a confirmed email address before reporting spam

Dear all, I am doing an eigenfrequency analysis of an unstable rock block to compare it with the modal analysis results I obtained with the accelerometer data that have been collected on the unstable rock. Everything is fine till this part. Now, I want to understand which is the direction at which the rock block vibrates during its first mode. I already plotted the modal shape with the "arrow" functionality but I would like to have something more precise. Therefore, I am asking you if is there any way to use polar plot in order to track the displacement of a specific point of the rock block. Thanks in advance.
