'txt' <set> ['n']|[['v'|'e'|'f'|'i']&['n']] [<dx> <dy>]
Creates node-attached texts (showing node-number and value, see figure
8) in the drawing area. The optional dx,dy values define an offset (normalized coordinates) to the actual node position on the screen where the origin is in the lower left corner:
txt nodset 0.1 0.2
The texts are attached to the related nodes if no location is specified:
The texts comprise of a node-nr and the value. The node-nr can be deselected by providing the key 'n' or the value can be deselected with key 'v'. The exponential format of the value can be selected with 'e', float with 'f' and integer with 'i':
txt nodset fn
deselects the node-nr and selects the float format for the value.
txt nodset n 0.1 0.5
de-selects the node-nr and places the value at a certain position.
The texts are generated but not displayed. The commands ''plot'' and ''plus'' can be used for that purpose. The texts can be deleted with ''del''. See also ''qtxt'' for the interactive command.
