<sect3 id="datafiletxt"><title>Data file name</title>
  <para>
    The name of the data file. It can be typed directly in the window provided, or selected with the help of the <guibutton>browse</guibutton> button.
  </para>
</sect3>
<sect3 id="initmethodtxt"><title>Grid initialization method</title>
  <para>
    For visualising grilled data, you need to <ulink url="./firststeps.html#load_grid">define the grid</ulink> on which are located the data. By default, "automatic grid construction with initncdf.pro" is checked. This means that the grid will be defined by using the informations contained in the data file (through the IDL prodecure <command>initncdf</command>) without needing any other auxillary file. If you checked "grid construction with other IDL batch or procedure", this means that you don't want to use the default <command>initncdf</command> procedure to define the grid and you will provide your own IDL procedure or the so-called IDL batch file (a file which is called by using @, see IDL documentation).
  </para>
</sect3>
<sect3 id="initprogramtxt"><title>Grid initialization parameters</title>
  <para>
    This third part allows you to specify the name, the argument and the keywords of the routine you want to use to initialize the grid.
By default the name of the procedure is <command>initncdf</command>, its argument will be automatically defined so you cannot change them. If you If you checked "grid construction with other IDL batch or procedure", you have to select the name of the IDL procedure or batch file and its suitable arguments and keywords. Note that if you select an IDL batch file you cannot give any parameter or keyword.

This is the same as the simple <link linkend="launch_xxx_1"><prompt>&promptidl;</prompt> <userinput><command>xxx</command></userinput></link> except that once the xxx window open, you will have 2 separate windows (command and plotting window) instead of one.

The domain we'd like to select for the plot is determined by one of
its diagonals, defined therefore by two points.
The first point is
defined when the mouse button is pushed, then the mouse is moved, and
the second point is defined as the mouse button is released
(click-drag).
The domains are thus defined by a long click (<abbrev>LC</abbrev>).
