Simulation plots may be conveniently selected, viewed with
@uref{http://www.gnuplot.org,gnuplot} 
and saved to file (in PostScript format) using the command

@example
mtt [options] rc gnuplot view
mtt [options] rc odeso gnuplot
@end example

This will cause a menu to be displayed, from which states and outputs may be selected for viewing. Clicking on a @emph{parameter name} will, by default, cause the time history of the selected parameter to be displayed.

As with @strong{xMTT} (@pxref{Menu-driven interface}), the Wish Tcl/Tk interpreter must be installed to make use of this feature.
