Note that Besides these functions however, the strings still contain gnuplot

Besides these functions however, the syntax is still the the gnuplot one. Note that these functions operates on the data and status we set up in
the previous example, i.e. we are operating in a **session**. This
allow to build a plot step by step and (optionally) to dump all data
and commands on a gnuplot script file, to be edited/used outside
Julia.
Now we will introduce a few more functions designed to produce
multiplots:

- `Gnuplot.multi`: initialize a multiplot session. This is typically
used at the beginning of the session but it can also be used after
the first plot;
- `Gnuplot.next`: move to the next plot in the multiplot session.
