Notes
- The color of the pivots is interpolated among the diagram points. Due to the discrete behavior of these pivots, the cut through a plane could give erroneous values, which must be interpreted adequately.
- To show these pivots with colors, the “beta” capacity must activated using the command: KEYW, BETACIVI, 1
