1. An alignment analyzer for facilitating the alignment of at least one machine set including first and second rotatable shafts connected respectively to first and second machines employing an alignment fixture for measuring a pair of offsets at a plurality of shaft rotational positions to establish a measured data set, said alignment analyzer comprising:

  • a display device capable of displaying a graphical representation in a coordinate system having a first coordinate representing offset misalignment and a second coordinate representing angular misalignment; and

    elements operating to calculate, based on the measured offset data set, the amount of offset misalignment, if any, and the amount of angular misalignment, if any, of the shafts in at least one plane, and to display combined offset and angular misalignment as a point in the coordinate system on said display device, said point being positioned with respect to the first coordinate based on the calculated amount of offset misalignment and being positioned with respect to the second coordinate based upon the calculated amount of angular misalignment.
