+
+The 'view' option includes the axis scale short-cuts such as Linear, Guinier, 
+Cross-sectional (XC) Guinier, and Porod plot scale. For a proper data set, 
+these axis scales can be used to estimate Rg, Rod diameter, or Background of 
+neutron scattering data respectively (via 'Linear Fit'; see below). For a 2D 
+image, *Right click*  on the image to pop-up the context menu. Select to 
+switch from linear to log scale. The scale selected is printed on the status

+
+Description
+-----------
+
+This feature allows you to perform different types of averages on your data, 
+and allows you to see what regions of the detector will contribute to the 
+average. The region to be averaged will be drown and can be modified by 
+dragging the lines around.
+
+.. _How_to_Average:
+
+How to Average
+--------------
+
+Right click on 2D data for the context menu to appear. Select one type of 
+averages among *"sector [Q view]", "Annulus [Phi view]", "Box sum", "Box 
+averaging in Qx ", "box averaging on Qy","Perform circular Average".*
+
+A slicer will appear except for *"Perform circular Average"*  that you can 
+drag by clicking on a slicer 's marker. When the marker is highlighted in red, 
+it means that the slicer can change size.You can also move some of the slicer 
+by simply drag its side when highlighted in red. the slicer size will be reset 
+to its previous size if the user try to select a region greater than the size 
+of the data.
+
+The user can also select a region to average when a slicer has been selected 
+already by *right clicking*  on the context menu and selecting *Edit Slicer 
+Parameters* . The dialog window will appears and the user can enter values to 
+selected a region or selected numbers of points to plot *nbins* .
+
+For *Box sum* , when the user selects this option, a new panel is created 
+containing the result of average of the sum of every pixels contains on that 
+data.The user can also enter values to select a region.
+
+.. _Available_Averagings:
+
+Available Averagings
+--------------------
+
+Some different types of averaging are provided for.
+
+.. _Unmasked_Circular_Average:
+
+Unmasked Circular Average
+-------------------------
+
+This operation will perform and average in constant q-rings around the (x,y) pixel
+location of the beam center.
+
+.. _Masked_Circular_Average:
+
+Masked Circular Average
+-----------------------
+
+This operation is same as 'Masked Circular Average' except that the masked
+region is excluded if masked.
+
+.. _Sector_Average:
+
+Sector Average [Q View]
+-----------------------
+
+This operation averages in constant q-arcs. The width of the sector is specified in
+degrees (+/- delta phi) each side of the central angle (phi).
+
+.. _Annular_Average:
+
+Annular Average [Phi View]
+--------------------------
+
+It performs an average between two q-values centered in (0,0), and averaged 
+over a width of a specified number of pixels. The data is returned as a 
+function of angle (phi) in degrees. Moving one circle of this slicer to 
+radius of zero corresponding to a circular averaging on radius qmax , the 
+outer circle. The angle zero starts from the positive x-axis direction.
+
+.. _Box_Sum:
+
+Box Sum
+-------
+
+Perform the sum of counts in a 2D region of interest.When editing the slicer, 
+the user can enter the length and the width the rectangle slicer and the 
+coordinates of the center of this rectangle.
+
+.. _Box_Averaging_in_Qx:
+
+Box Averaging in Qx
+-------------------
+
+Computes average I(Qx) for a region of interest. When editing the slicer, the 
+user can control the length and the width the rectangle slicer. The averaged 
+output is calculated from the constant bins with rectangular shape. The 
+resultant q values are nominal values, i.e., the central values of each bins 
+on the x-axis.
+
+.. _Box_Averaging_in_Qy:
+
+Box Averaging in Qy
+-------------------
+
+Computes average I(Qy) for a region of interest.When editing the slicer, the 
+user can control the length and the width the rectangle slicer. The averaged 
+output is calculated from the constant bins with rectangular shape. The 
+resultant q values are nominal values, i.e., the central values of each bins 
+on the y-axis.

+
+Floating Panel
+--------------
+
+For a graph panel to float on the top of the SV window:
+
+Press the *Ctrl(Cmd on MAC) key*  on dragging and placing a panel. Or if you 
+want to make all plot panels float, select 'Float' from Graph/Preperences in 
+the menu bar. Otherwise choose 'Dock'.
+

+
+Graph Context Menu
+------------------
+
+To get the graph context menu to print, copy, save data, (2D)average, etc, 
+*locate the mouse point on the plot to highlight and *(Mouse) Right Click* 
+to bring up the full menu.
+
+.. _Zoom:
+
+Zoom In/Out
+-----------
+
+To Zoom in or out the full plot, *locate the mouse point inside the graph 
+which will be the center of the zooming, then *rotate MouseWheel*.
+
+*To Zoom in or out the plot in x or y direction, *locate (and click) the 
+mouse point near x (or y) axis just outside of the graph and then *rotate 
+MouseWheel* .* Note that this works only on the 1D plots.
