283<p>Using IDL <span><strong class="command">plot</strong></span>
284command is quite inconvenient to save the figure as a postscript.
285In addition, positioning the figure on the window/page by using
286<code class="varname">!p.position</code>, <code class=
287"varname">!p.region</code> and <code class=
288"varname">!p.multi</code> is often a nightmare. That's why we
289developed <span><strong class="command">splot</strong></span> (like
290super-plot) which can be used in the same way as plot but is much
291more convenient to make postscript and position the figure.</p>

880<p>When the grid is really irregular (its abscissa and ordinate
881cannot be descried by a vector), loading the grid directly from the
882data forces us to make an approximation when computing the grid
883corners position and the cells size. In that case, it can be
884preferable to load the grid from the meshmask file created by OPA.
885As OPA use a Arakawa-C discretization, loading the grid from the
886meshmask will also define all parameters related to the U, V and F
887grids (glam[uv],gphi[uv], e[12][uvf]). Note that, when using a
888simple <a href="#load_fromdata" title=

890grid definition from the data itself</a> (with <code class=
891"filename">initncdf</code> or <code class=
892"filename">computegrid</code>), adding the keyword /FULLCGRID leads
893also to the definition of all U, V and F grids parameters. There is
894the examples to load ORCA grids from OPA meshmask.</p>
