11The data explorer
12-----------------
13
14*Data Explorer* is a panel that allows the user more interactions with data.
15Some functionalities provided by the *Data Explorer* are also available through
16the context menu of plot panels or other menus within the application.
17
18Under *View* in the menu bar, *Data Explorer* can be toggled between Show and
19Hide by clicking *Show/Hide Data Explorer*.
20
21*NOTE! When* Data Explorer *is hidden, all data loaded will be sent directly
22to the current active analysis perspective, if possible. When* Data Explorer *is
23shown, data go first to the* Data Explorer.

87Appending plots to a graph
88--------------------------
89
90This operation can currently only be performed on 1D data and plot panels
91containing 1D data.
92
93Click on the button *Append Plot To* to add selected data to a plot panel. Next
94to the button is a combo box containing the names of available plot panels.
95Selecting a name from this combo box will move that plot into focus.

105-------------------
106
107The *Freeze Theory* button generates data from the selected theory.
108
109*NOTE! This operation can only be performed when theory labels are selected in*

121
122*Batch mode* provides serial (batch) fitting with one model function, that is,
123fitting one data set followed by another. If several data sets need to be
124fitted at the same time, use *Simultaneous* fitting under the *Fitting* 
125option on the menu bar.
