Introduction
------------

*Data Explorer* is a panel that allows the user more interactions with data. 
Some functionalities provided by the *Data Explorer* are also available through 
the context menu of plot panels or other menus within the application.

Under *View* in the menu bar, *Data Explorer* can be toggled between Show and 
Hide by clicking *Show/Hide Data Explorer*.

*NOTE! When* Data Explorer *is hidden, all data loaded will be sent directly 
to the current active application, if possible. When* Data Explorer *is 
shown, data go first to the* Data Explorer.

.. _Activate_Data:

Activate Data
-------------

To interact with data it must be activated. This is accomplished by checking 
the box next to the data label. A green tick will appear.

Unchecking/unticking the box deactivates a data set.

There is also a combo box labeled *Selection Options* from which you can 
activate or deactivate multiple data sets.

.. _Remove_Data:

Remove Data
-----------

*WARNING!* Remove Data *will stop any data operations currently using the 
selected data sets.*

*Remove Data* removes all reference to selected data from the application.

.. ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ

.. _Append_Plot_to_Graph:

Append Plot to Graph
--------------------

This operation can only be performed on 1D data and plot panels currently 
containing 1D data.

Click on the button *Append To* to add selected data to a plot panel. Next to 
the button is a combo box containing the names of available plot panels. 
Selecting a name from this combo box will move that plot into focus.
 
If a plot panel is not available, the combo box and button will be 
disabled.

2D Data cannot be appended to any plot panels.

The *Freeze Theory* button generates data from the selected theory.

*NOTE! This operation can only be performed when theory labels are selected.*

.. ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ

.. _Send_Data_to_Applications:

Send to Application
-------------------

Click on the button *Send To* button to send the currently selected data to 
a perspective (for *Fitting*, *P(r) Inversion*, or *Invariant* calculation).
 
The *Single*/*Batch* mode radio buttons only apply to the *Fitting* perspective.

*Batch mode* provides serial (batch) fitting with one model function, that is, 
fitting one data set followed by another. If several data sets need to be 
fitted at the same time, use *Simultaneous* fitting under the *Fitting* 
option on the menu bar.
