Uniplex

The uniplex driver is able to combine several plots in one image. The option portrait causes the image to be drawn in a window where the width is about 2/3 of the height (default is landscape—the image height is about 2/3 of the width). The fontsize may also be specified (sizes 1–8). Only one image is allowed per file. If an 'X' is included in the set output filename, the 'X' is replaced by a sequential plot number.

Options are:

      portrait
      landscape        (default)
      [ x , y ]        (where x and y are the number of plots in the x and y
                        directions of the image)
      n                (where n is fontsize (1--8))

To plot 6 plots in one image in two columns in portrait orientation:
