First Claim
1. A method of displaying machine vibration data indicative of vibration produced during transient operation of rotating equipment, the method comprising the steps of:
- a. receiving the machine vibration data at an electronic device having a display, the machine vibration data expressed as vibration peak amplitude versus vibration phase angle versus RPM;
b. displaying an image corresponding to the machine vibration data on the display in a three-dimensional graph in which the vibration peak amplitude and vibration phase angle are depicted in a polar plot as a function of RPM of the rotating equipment during the transient operation, the three-dimensional graph including an RPM axis that is perpendicular to the polar plot; and
c. rotating the three-dimensional graph about an axis of rotation in response to input to the electronic device.

Abstract
Methods for displaying machine data are described including a method for displaying machine data as a virtual three-dimensional image showing a three-dimensional graph having three axes such that the data in the graph may be rotated about one or more of the axes to give a data analyst a better perspective of the behavior of an item being monitored. In a related embodiment, a method for displaying machine data in a virtual three-dimensional image such that the data may be rotated one or more of the axes is described which further includes one or more cursor images representing substantially planar cursors on the display for analyzing data.
