Toggle Vector-Plot

It is possible to add small ``needles'' to the plot which point with there head in the direction of the vector. Only entities which are marked in the database as vectors will be affected. See ``Nodal Results Block'' how entities are marked as vectors. Internally calculated vector-results like the worst principal stress are marked automatically.

- The command takes effect after the next entity selection.
- If one component or the value of a vector is selected then the option takes effect.

This option can be used in combination with ``Animate Toggle Dataset Sequence''.
See also the keyboard command ``lc'' how to select datasets and entities without the menu. In this case also entities which are NOT marked in the dataset as vectors can be displayed with vector-needles. This command line approach is the only way to display duns-cfd-results with vector-needles. See also the command ``scal'' how to manipulate the length of the vectors.
