     76The EXCLEDT program displays the data in a graph, (see the example above)
    7677with the observed data as data points (black X's by default)
    7778and the computed values as a line (red by default). Any excluded data points

    103104In <B>Add Region mode</B>, the mouse is used to map out a region which that
    104105will be excluded from the refinement. When this button is selected, the
    105106mouse cursor changes to an arrow. After the left mouse is pressed once,
    106 a yellow background is shown for the excluded region and when the left mouse
     107a yellow background is shown for the excluded region, as is seen below.
     108When the left mouse
    107109button is pressed a second time, the region is selected.
    108110If the right mouse button is pressed instead, it resets the region selection.

     134Zoom settings can also be entered manually by pressing the "Z" key. This
     135opens a dialog, as is shown to the right, where the x- or y-axis range
     136can be specified. Any value that is not specified is set to the maximum
     137or minimum for the entire dataset. It is possible to zoom further in using
     138the mouse, but to zoom out beyond the manual zoom limits, the "reset" button
     139on the manual zoom menu must be used.

     142If more than one histogram is available to plot, it is possible to cycle

    127149At the bottom of the window is a set of buttons with the minimum and maximum
    128150limit on the data as well as a button for every excluded region. Pressing
    129151a button causes a window to be opened to edit that region by manually entering

     156In the case where a dummy histogram will be edited, the information presented
     157in this box is formatted slightly differently (as shown to the right).
     158Pressing the set button creates a dialog box where the data range can be set,

     164If the upper data limit is raised (or d-min is lowered) this message is

     184When the data range is edited, a box such as the one to the right will appear
     185to set the data limits and step size. Note that these values are always
     186displayed in the native units for the histogram (degrees, microseconds or Kev)
     187regardless of the setting for the x-axis units, since the step size is constant
     188in these native units. The data range is also shown in d-space and Q.
     190Note that it is not possible to edit the data range for
     191histograms with varying steps. At this time, this only affects
     192dummy TOF histograms simulated with logarithmic steps. The range can be
     193changed in the EXPEDT program.
