This option displays a menu with results from vectors and matrices (where the principal values have been previously evaluated by the program). From the menu of variables, choose the one you wish to see displayed; it will be shown with the default analysis and step (this can be changed with the Default Analysis/Step option in the menu). Once a result is chosen, the program will display the nodal vectors of the chosen result. The vectors that are drawn can be scaled interactively. The factor can be applied several times and every time it changes to the new input value.
You can modify the colour color of the vectors, which by default are drawn in green, so that all the vectors are drawn in the same colourcolor, or you can let the color of the vectors vary according to the result module.
