It is possible to write character strings on graphics using frames. First a title can be put under the frame using the command of the same name :
- funct -> title X f My title is Here
will write "My title is Here" on the graphic X window below the rectangle defined by the frame f.
It is also possible to write inside frames, using the command putstring :
- funct -> putstring X f -NO My string is Here
will write "My string is Here" at the current position on the graphic X window with respect to the frame f. Here "-NO" is a modifier that moves slightly the position where the string begins on the graphic (allowed modifiers are "-O", "-E", "-S", "-N", "-NO", "-NE", "-SE", "-SO", with an obvious meaning). This is useful for points on geometric pictures.
