=== Start IDL session: @init ===
Each IDL session using SAXO must always start with:
{{{
#!html
idl> @init
}}}
''The @ is equivalent to an include. It is used to execute a set of IDL commands that will be directly executed without any compilation (as it is the case for a procedure or a function). All variables defined and used in the @… file will still be accessible after the execution of the @… is finished (which is not the case for procedures and functions that ends with the return instruction).''

As an IDL session using SAXO must always start with :
{{{
#!html
idl> @init
}}}
, it could be convenient to define the environment variable IDL_STARTUP to {{{${HOME}/My_IDL/init.pro}}}. In that way, {{{init.pro}}} will automatically been executed when starting IDL. This can be done with the following command:
'''csh'''
{{{
#!html
$ setenv IDL_STARTUP ${HOME}/My_IDL/init.pro
}}}
'''ksh'''
{{{
#!html
$ export IDL_STARTUP=${HOME}/My_IDL/init.pro

[[Image(source:/trunk/SRC/Documentation/xmldoc/images/callouts/1.png)]]
{{{findgen}}} stands for '''f'''loat '''ind'''ex '''gen'''erator.

Using IDL {{{plot}}} command is quite inconvenient to save the figure as a postscript. In addition, positioning the figure on the window/page by using {{{!p.position}}}, {{{!p.region}}} and {{{!p.multi}}} is often a nightmare. That's why we developed {{{splot}}} (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.
{{{

If needed, the name of the postscript will automatically be completed with .ps. Just hit return, if you want to use the default postscript name: {{{idl.ps}}}.

{{{splot}}} accepts the same keywords as {{{plot}}} (/ISOTROPIC, MAX_VALUE=value, MIN_VALUE=value, NSUM=value, /POLAR, THICK=value, /XLOG, /YLOG, /YNOZERO), including the graphics keywords (BACKGROUND, CHARSIZE, CHARTHICK, CLIP, COLOR, DATA, DEVICE, FONT, LINESTYLE, NOCLIP, NODATA, NOERASE, NORMAL, POSITION, PSYM, SUBTITLE, SYMSIZE, T3D, THICK, TICKLEN, TITLE, [XYZ]CHARSIZE, [XYZ]GRIDSTYLE, [XYZ]MARGIN, [XYZ]MINOR, [XYZ]RANGE, [XYZ]STYLE, [XYZ]THICK, [XYZ]TICKFORMAT, [XYZ]TICKINTERVAL, [XYZ]TICKLAYOUT, [XYZ]TICKLEN, [XYZ]TICKNAME, [XYZ]TICKS, [XYZ]TICKUNITS, [XYZ]TICKV, [XYZ]TICK_GET, [XYZ]TITLE, ZVALUE).
It can therefore be customized ''as much as you want''. See this short example:
{{{
#!html
idl> splot, y, y^2, linestyle = 2, thick = 2, title = 'y = x^2', /portrait [source:/trunk/SRC/Documentation/xmldoc/figpng/basic_splot2.png show result]
}}}
{{{splot}}} can be used to setup the graphic environment ({{{!p}}}, {{{!x}}}, {{{!y}}}, {{{!z}}} variables) needed by procedures like {{{oplot}}}
{{{
#!html
idl> splot, y, yrange = [0, (n-1)^2], title = 'x and x^2'
idl> oplot, y^2, color = 50, linestyle = 2 [source:/trunk/SRC/Documentation/xmldoc/figpng/basic_splot4.png show result]
}}}
Use the keyword small to produce multi plots figures.
{{{
#!html
idl> splot, y, y^2, title = 'y = x^2', psym = 2, small 1 = [1, 2, 1]
idl> splot, findgen(360)/36., findgen(360)*2.*!dtor, /polar $
idl> , small 1 = [1, 2, 2], /noerase 2 [source:/trunk/SRC/Documentation/xmldoc/figpng/basic_splot3.png show result]
}}}
[[Image(source:/trunk/SRC/Documentation/xmldoc/images/callouts/1.png)]]
the small keyword is a 3 elements vector which defines how we divide the page and in which case we should make the plot: [number of columns, number of rows, case number]. The case numbering is starting at 1, from top to bottom and left to right.
[[Image(source:/trunk/SRC/Documentation/xmldoc/images/callouts/2.png)]]
you must put /noerase otherwise the second plot will be done in a new window.
==== scontour ====
Following {{{splot}}} example, we provide {{{scontour}}} as a "super contour".
{{{
#!html
idl> z = dist(n)
% Compiled module: DIST.
idl> scontour, z [source:/trunk/SRC/Documentation/xmldoc/figpng/basic_scontour1.png show result]
% Compiled module: SCONTOUR.
% Compiled module: CHKSTRU.
}}}
{{{scontour}}} accepts the same keywords as {{{contour}}} (C_ANNOTATION=vector_of_strings, C_CHARSIZE=value, C_CHARTHICK=integer, C_COLORS=vector, C_LABELS=vector{each element 0 or 1}, C_LINESTYLE=vector, { /FILL | /CELL_FILL | C_ORIENTATION=degrees}, C_SPACING=value, C_THICK=vector, /CLOSED, /DOWNHILL, /FOLLOW, /IRREGULAR, /ISOTROPIC, LEVELS=vector, NLEVELS=integer{1 to 60}, MAX_VALUE=value, MIN_VALUE=value, /OVERPLOT, {/PATH_DATA_COORDS, PATH_FILENAME=string, PATH_INFO=variable, PATH_XY=variable}, TRIANGULATION=variable, /PATH_DOUBLE, /XLOG, /YLOG, ZAXIS={0 | 1 | 2 | 3 | 4}), including the [#FirststepswithSAXO] (except LINESTYLE, PSYM, SYMSIZE).
It can therefore be customized ''as much as you want''. See these short examples:
{{{
#!html
idl> scontour, z, /fill, nlevels = 15, subtitle = 'nicer contour' $
idl> , xtitle = 'x index', charsize = 1.5 [source:/trunk/SRC/Documentation/xmldoc/figpng/basic_scontour2.png show result]
}}}
It can be used in combination with contour to make more complex plots:
{{{
#!html
idl> ind = findgen(2*n)/(2.*n)
idl> scontour, z, levels = n*ind, c_orientation = 180*ind, c_spacing = 0.4*ind
idl> contour, z, /overplot, c_label = rebin([1, 0], 2, n) 1, levels = n*ind $
idl> , c_charthick = 2, c_charsize = 1.5, c_colors = 250*ind [source:/trunk/SRC/Documentation/xmldoc/figpng/basic_scontour3.png show result]
}}}
[[Image(source:/trunk/SRC/Documentation/xmldoc/images/callouts/1.png)]]
{{{rebin}}} is used to build an array containing an alternation of 1 and 0 in order to label one contour every two contours.
{{{
#!html
idl> print, rebin([1, 0], 2, 3)
1 0
1 0
1 0
}}}
{{{scontour}}} is compatible with the positioning method associated with the small keyword. See for example the test file [source:/trunk/SRC/Tests/tst_basic.pro tst_basic.pro]:
{{{
#!html
idl> tst_basic [source:/trunk/SRC/Documentation/xmldoc/figpng/tst_basic.png show result]

==== Quick look and explore 2D arrays: tvplus ====
{{{tvplus}}} is a enhanced version of {{{tvscl}}} and allow you to have a quick look and perform basic exploration of 2D arrays.

== Explore gridded data (model outputs and observations) ==
This section briefly describes the main functionalities offered by SAXO to explore gridded data on regular or irregular grid.
=== Load the data grid ===
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 {{{${HOME}/SAXO_DIR/Tests/}}}, we provide several examples to load a grid.
==== Easiest solution: load data grid (regular or not) directly from the data file ====
Example of Levitus temperature on a regular 1x1 grid.

==== Load the grid from OPA meshmask file ====
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 [#FirststepswithSAXO] (with {{{initncdf}}} or {{{computegrid}}}), 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.

=== Hovmoellers and time series ===
A quick presentation of hovmoellers and time series is shown in [source:/trunk/SRC/Tests/tst_pltt.pro tst_pltt]. After loading any of the grid (for example with one of the [#FirststepswithSAXO]). Just try:
{{{
#!html
idl> tst_pltt
}}}
''Beware, the command is tst_pltt and not @tst_pltt as tst_pltt.pro is a procedure and not an include.''
