Here we must use x as the independent variable. This is done in conjuction with specifying the plot range: plot [t=-4:4] exp(-t**2 / 2), t**2 / 16 Defining Functions Sometimes, it may be convenient to define a function, so that The boxes style draws a box centred about the given x coordinate from the yaxis to the given y coordinate.
