Hello,

There is not any special draw options to declare the internal dimensions
of the scenes, but you can make use of user_preamble to add some gnuplot
code to maxout.gnuplot.

Here is a workaround:


draw(
    dimensions = 100*[21,29.7],
    terminal = pdfcairo,

    gr2d(
        explicit(x^2,x,-1,1),
        user_preamble=["set size 1.0, 0.75","set origin 0.0, 0.25"]),

    gr3d(
        explicit(x^2+y^2,x,-1,1,y,-1,1),
        user_preamble=["set size 1.0, 0.25","set origin 0.0, 0.0"]))$


With variable 'origin', you tell Gnuplot where to start drawing the
scene (lower-left corner). Since you are allocating the scenes by hand,
you don't need to use option 'columns'.

With variable 'size', you declare the dimensions, in relative units, of
a particular scene. For example, with "set size 1.0, 0.75", the 2D scene
will use 100% and 75% of the available width and height, respectively.

Finally, with the values given to option 'dimensions' you'll get a pdf
document of size A4.

I hope this fits your needs.
