Display a 1D trace of the spectrum matrix for the given spectrum in the given window dimension in the current window. The vector shown is defined by the currently visible area in the window, and the ruler in the given dimension. The special window is created if it does not exist. The points are equally spaced along the ppm scale. The command without parameters removes the 1D window.
Further input is taken from the tty rather than the graphics.
It is the same command as picking the item tty in the command menu. This command is useful to remove the display of a certain spectrum if it is irrelevant or otherwise unwanted in a graphics window. This can be useful if one wants to update the graphics after having, for instance, moved windows, without having to go to graphics mode. It may also be useful in writing macros. The given dimensions fd1 and fd2 refer to the spectrum dimensions that are to be displayed as the window dimension F1 and F2, respectively.
