@page LEVEL2 Data Products GUIs

There are two main GUIs for viewing Trick logged data: 

@li @ref TrickDP "6.4.1 Trick DP" 
@li @ref TrickQP "6.4.2 Trick QP" 

These two applications work together and allow the user to plot and tabularize Trick data. 

@li @ref ViewingData "6.4.3 Viewing Data"

This section gives various examples of viewing Trick logged data using @ref TrickDP "Trick DP" and @ref TrickQP "Trick QP".

@anchor TrickDP
@section LEVEL3 Trick DP - Data Products Application

The trick_dp (data products) is designed to make use of data product specification files (DP_ files). DP_ specification
files are input files which tell data products how and what to display in plots and tables. If time is taken to create the DP_
specification files, this tool shows its power in perusing large sets of data. The “Help” menu option on the GUI also gives
detailed information on its use. To launch the program:

@li <b>UNIX Prompt></b> trick_dp&

the first time to run trick_dp on this machine, all previously imported SIMs will be displayed also. 

SIMs initially appear unexpanded in the @ref SimsRunsTreeArea "Sims/Runs Tree". Double clicking a SIM_ node or 
single clicking the node icon on the left will show runs contained in that SIM_. Runs in black contain data and

In this section, <b>SIM_cannon_analytic</b> that comes with Trick distribution and is located at $TRICK_HOME/trick_sims will be used. 
Assuming you already have had corresponding data recorded by executing the related sim. The data from a single run will be viewed 
using @ref TrickDP "Trick DP" together with @ref TrickQP "Trick QP". When plotting, single plotting is used. Please see Trick Tutorial 
for more examples that also have comparison or error plotting with multiple runs. You certainly can perform similar exercises using your own sim.

Begin by launching @ref TrickDP "Trick DP".
@li <b>UNIX Prompt></b> cd <path_to_sim_cannon_analytic>/SIM_cannon_analytic
@li <b>UNIX Prompt></b> trick_dp &

@section LEVEL5 Plotting Time -vs- Postion
-# Double click the pathname containing your sim directory if it is not expanded yet (or single click the symbol next to the name)
-# Double click the @c SIM_cannon_analytic name in the @ref SimsRunsTreeArea "Sims/Runs Tree". This will reveal the @c RUN_test directory.
-# Double click the @c RUN_test name or right click the @c RUN_test followed by selecting "Add run(s)". 
   This will bring @c RUN_test into the @ref RunSelectionsArea "RUN Selections" below.
-# Click the blue lightning button in the tool bar to launch Quickplot application (@ref TrickQP "Trick QP"). The @ref TrickQP "Trick QP" GUI will pop up.
-# In @ref TrickQP "Trick QP", right click @c dyn.cannon.pos[0-1] and select "Expand Var" if the interested variable is one of the element in an array 
   which is not expanded yet.
-# Double click the @c dyn.cannon.pos[0] variable in the left pane. This sets up to create one page with one plot (time -vs- pos[0]).
    - Make sure nothing is highlighted or "Plots" is highlighted on the right in @ref DPContentArea "DP Content"
    - If "Tables" is highlighted, it sets up to create a table with one column instead.
    - The X variable is @c sys.exec.out.time by default and the Y variable is dyn.cannon.pos[0].
    - Later, you will learn how to replace the X (@c sys.exec.out.time) with a different variable.
-# Now click the @c dyn.cannon.pos[1] variable and drag it to the pane on the right. Drop it on the line with "Page" (see the white-n-black window looking icon). 
   This will result in one page containing two plots.
-# In @ref TrickQP "Trick QP", click the plain white sheet icon located on the toolbar. A single window with two plots should pop up:

-# If you want to specify the number of plots horizontally and vertically on a page, click "Page" node and edit its Horizontal Cells and Vertical Cells 
   propterties from @ref PropertyNotebookArea "Proptery Notebook" (use the scroll bar or change the GUI window size if necessary). Change Horizontal Cells 
   from 0 to 2 and Vertical Cells from 0 to 1 and click "Apply Change" button on the top of @ref PropertyNotebookArea "Proptery Notebook". 
   If click the plain white sheet icon located on the toolbar, a single window with two plots side by side should pop up:

Now, let's change the default X variable from @c sys.exec.out.time to a different variable.
-# Assuming the @ref TrickQP "Trick QP" application is still up, click the "New" plot icon located on the far left of the toolbar.
   Click "Ok" when asked if you want to start over. This will clear the plots from the @ref DPContentArea "DP Content".
-# Double-click @c dyn.cannon.pos[1].
-# Drag-n-drop the @c dyn.cannon.pos[0] variable over the @c sys.exec.out.time variable in the Plot located in the @ref DPContentArea "DP Content". 
   You will be asked to confirm the replacement. Click "Ok".
    - Now, the X variable is @c dyn.cannon.pos[0] and the Y variable is @c dyn.cannon.pos[1].

Now that @c DP_cannon_xy has been saved, the data can be viewed with @ref TrickDP "Trick DP".
-# Assuming the @ref TrickDP "Trick DP" is still up and running from the previous steps, Click “Session->Refresh...”
and double click SIM_cannon_analytic to reveal DP_cannon_xy.xml in the top right pane.
    - If the @ref TrickDP "Trick DP" is not up, go to the sim directory and launch it as:
        - <b>UNIX Prompt></b> trick_dp &
-# Make sure that Sims/Runs->SIM_cannon_analytic/RUN_test has been selected.
    - You can tell by checking to see if it is listed in @ref RunSelectionsArea "Run Selections".
-# Choose the @c DP_cannon_xy.xml in the top right pane by double clicking it or right click followed by selecting "Add DPs".
    - This will bring the DP_cannon_xy.xml into the DP selections pane.
-# To see the trajectory again, click the plain white single sheet icon on the toolbar.
Zoom in by holding the middle mouse button and drag across a section of the plot. Then release the
