     34*Data Explorer* is a panel that allows the user more interactions with data.  
     35Some functionalities provided by the Data Explorer are also available through  
     36the context menu of plot panels or other menus of the applications.Under menu  
     37*View*  of the menubar, Data explorer can be toggled between Show and Hide by  
     38clicking the menu *Show/Hide Data Explorer* . 
     39 
     40*IMPORTANT!*  When Data explorer is hidden, all the data loaded will be sent  
     41directly to the current active application, if possible. When data Explorer is  
     42shown data go first to the Data Explorer for the user to handle them later.

     96 
     97From the context menu, select 'Save points as a file' for 1D, or 'Save as a  
     98file(DAT)' for 2D. Note that two formats, txt and xml, are available in 1D  
     99saving. 
     100 
     101.. _Drag_Plot: 
     102 
     103Drag Plot 
     104--------- 
     105 
     106Select the *crossed arrows*  button on the plot panel *toolbar*  to drag the  
     107plot. To disable dragging mode, unselect the same button on the toolbar.

     113 
     114Select the *rectangle*  button on the plot panel *toolbar*  to zoom in a 
     115region of the plot. 
     116 
     117To disable zoom mode, unselect the same button on the toolbar. After zoom in 
     118a region, select *left arrow*  or *right arrow*  button on the toolbar to set 
     119the graph the the previous size. If a mouse wheel button is available, 
     120*zoom in/out*  by scrolling the mouse wheel (see Key_Sequences_ help for 
     121details). 
     122 
     123.. _Remove_Data_from_Plot: 
     124 
     125Remove Data from Plot 
     126--------------------- 
     127 
     128Highlight the plot and the context menu appears.Select *remove [file name]*. 
     129The plot selected will disappear. 
     130 
     131.. _Change_Scale: 
     132 
     133Change Scale 
     134------------ 
     135 
     136If the loaded data is a 1-D data changing scale or data representation will  
     137work as follows. *Right click* on the plot window. A context menu pops-up and  
     138select *Change Scale* . A dialog window titled *select the scale of the graph*  
     139will pop-up then change the *x* , the *y*  and the *view*  values as wish. 
     140 
     141The 'view' option includes the axis scale short-cuts such as Linear, Guinier,  
     142Cross-sectional (XC) Guinier, and Porod plot scale. For a proper data set,  
     143these axis scales can be used to estimate Rg, Rod diameter, or Background of  
     144neutron scattering data respectively (via 'Linear Fit'; see below). For a 2D  
     145image, *Right click*  on the image to pop-up the context menu. Select to  
     146switch from linear to log scale. The scale selected is printed on the status  
     147bar. 
     148 
     149If the loaded data is an image. *Right click*  on the image to pop-up the 
     150context menu. Select to switch from linear to log scale. The scale selected is 
     151printed on the status bar. 
     152 
     153.. _Linear_Fit: 
     154 
     155Linear Fit 
     156---------- 
     157 
     158Linear fit is to perform a line model fitting keeping the scale of the plot. 
     159Highlight data to fit. From the context menu select *Linear Fit* . A dialog 
     160window appears. Change model initial parameters, data limits and hit *fit* 
     161button. New parameters values are displayed and the line with the new 
     162parameters is added to the plot. Especially for Guinier, XC Guinier, and 
     163Porod plot scale, this 'Linear Fit' will provides Rg, Rod diameter, and 
     164background, respectively. The following figure shows an example for the 
     165Guinier scale.

     210 
     211This feature allows you to perform different types of averages on your data,  
     212and allows you to see what regions of the detector will contribute to the  
     213average. The region to be averaged will be drown and can be modified by  
     214dragging the lines around. 
     215 
     216.. _How_to_Average: 
     217 
     218How to Average 
     219-------------- 
     220 
     221Right click on 2D data for the context menu to appear. Select one type of  
     222averages among *"sector [Q view]", "Annulus [Phi view]", "Box sum", "Box  
     223averaging in Qx ", "box averaging on Qy","Perform circular Average".* 
     224 
     225A slicer will appear except for *"Perform circular Average"*  that you can  
     226drag by clicking on a slicer 's marker. When the marker is highlighted in red,  
     227it means that the slicer can change size.You can also move some of the slicer  
     228by simply drag its side when highlighted in red. the slicer size will be reset  
     229to its previous size if the user try to select a region greater than the size  
     230of the data. 
     231 
     232The user can also select a region to average when a slicer has been selected  
     233already by *right clicking*  on the context menu and selecting *Edit Slicer  
     234Parameters* . The dialog window will appears and the user can enter values to  
     235selected a region or selected numbers of points to plot *nbins* . 
     236 
     237For *Box sum* , when the user selects this option, a new panel is created  
     238containing the result of average of the sum of every pixels contains on that  
     239data.The user can also enter values to select a region. 
     240 
     241.. _Available_Averagings: 
     242 
     243Available Averagings 
     244-------------------- 
     245 
     246Some different types of averaging are provided for. 
     247 
     248.. _Unmasked_Circular_Average: 
     249 
     250Unmasked Circular Average 
     251------------------------- 
     252 
     253This operation will perform and average in constant q-rings around the (x,y) pixel 
     254location of the beam center. 
     255 
     256.. _Masked_Circular_Average: 
     257 
     258Masked Circular Average 
     259----------------------- 
     260 
     261This operation is same as 'Masked Circular Average' except that the masked 
     262region is excluded if masked. 
     263 
     264.. _Sector_Average: 
     265 
     266Sector Average [Q View] 
     267----------------------- 
     268 
     269This operation averages in constant q-arcs. The width of the sector is specified in 
     270degrees (+/- delta phi) each side of the central angle (phi). 
     271 
     272.. _Annular_Average: 
     273 
     274Annular Average [Phi View] 
     275-------------------------- 
     276 
     277It performs an average between two q-values centered in (0,0), and averaged  
     278over a width of a specified number of pixels. The data is returned as a  
     279function of angle (phi) in degrees. Moving one circle of this slicer to  
     280radius of zero corresponding to a circular averaging on radius qmax , the  
     281outer circle. The angle zero starts from the positive x-axis direction. 
     282 
     283.. _Box_Sum: 
     284 
     285Box Sum 
     286------- 
     287 
     288Perform the sum of counts in a 2D region of interest.When editing the slicer,  
     289the user can enter the length and the width the rectangle slicer and the  
     290coordinates of the center of this rectangle. 
     291 
     292.. _Box_Averaging_in_Qx: 
     293 
     294Box Averaging in Qx 
     295------------------- 
     296 
     297Computes average I(Qx) for a region of interest. When editing the slicer, the  
     298user can control the length and the width the rectangle slicer. The averaged  
     299output is calculated from the constant bins with rectangular shape. The  
     300resultant q values are nominal values, i.e., the central values of each bins  
     301on the x-axis. 
     302 
     303.. _Box_Averaging_in_Qy: 
     304 
     305Box Averaging in Qy 
     306------------------- 
     307 
     308Computes average I(Qy) for a region of interest.When editing the slicer, the  
     309user can control the length and the width the rectangle slicer. The averaged  
     310output is calculated from the constant bins with rectangular shape. The  
     311resultant q values are nominal values, i.e., the central values of each bins  
     312on the y-axis.

     354To Zoom in or out the full plot, *locate the mouse point inside the graph  
     355which will be the center of the zooming, then *rotate MouseWheel*. 
     356 
     357*To Zoom in or out the plot in x or y direction, *locate (and click) the  
     358mouse point near x (or y) axis just outside of the graph and then *rotate  
     359MouseWheel* .* Note that this works only on the 1D plots.
