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

     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>

    217         As we focus in this section on the gridded data, we must first load the grid informations before reading and plotting the data. Loading the grid independently of the data allow you to reload the grid only when it is strictly necessary and not every time you access the data. In <code class="filename"><code class="envar">${HOME}</code>/SAXO_DIR/Tests/</code>, we provide several examples to load a grid.

    270           When the grid is really irregular (its abscissa and ordinate cannot be descried by a vector), loading the grid directly from the data forces us to make an approximation when computing the grid corners position and the cells size. In that case, it can be preferable to load the grid from the meshmask file created by OPA. As OPA use a Arakawa-C discretization, loading the grid from the meshmask will also define all parameters related to the U, V and F grids (glam[uv],gphi[uv], e[12][uvf]). Note that, when using a simple <a href="#load_fromdata" title="2.1.1.&nbsp;&#xA;  Easiest solution: load data grid (regular or not) directly from the data file.&#xA;">grid definition from the data itself</a> (with <code class="filename">initncdf</code> or <code class="filename">computegrid</code>), adding the keyword /FULLCGRID leads also to the definition of all U, V and F grids parameters. There is the examples to load ORCA grids from OPA meshmask.

     849<p>When the grid is really irregular (its abscissa and ordinate 
     850cannot be descried by a vector), loading the grid directly from the 
     851data forces us to make an approximation when computing the grid 
     852corners position and the cells size. In that case, it can be 
     853preferable to load the grid from the meshmask file created by OPA. 
     854As OPA use a Arakawa-C discretization, loading the grid from the 
     855meshmask will also define all parameters related to the U, V and F 
     856grids (glam[uv],gphi[uv], e[12][uvf]). Note that, when using a 
     857simple <a href="#load_fromdata" title=

     859grid definition from the data itself</a> (with <code class= 
     860"filename">initncdf</code> or <code class= 
     861"filename">computegrid</code>), adding the keyword /FULLCGRID leads 
     862also to the definition of all U, V and F grids parameters. There is 
     863the examples to load ORCA grids from OPA meshmask.</p>
