 option displays the data using the parameters specified in the Vertical viewing range setting. To 
 configure the graph to automatically scale to a range defined by the minimum and maximum data 
 points in the current view, select the "Auto-scale to data view" option. To keep the 
 y=0 value in view at all times when Auto-scale is selected, set "Always include 
 zero&quot; to &quot;ON&quot;.</p>
 <ul>
   <li>When viewing signal tracks within a composite group use
   &quot;group auto-scale&quot; to enable having all tracks scaled against the one track
   in the group that has the highest maximum data points in the current view.
   For example, below is a side-by-side image of two views of the same data from a selection
   of cell lines within a composite of related RNA-seq experiments. On the left is the
   original &quot;auto-scale to data view&quot; setting, where each track is auto-scaled
   to appear at each track's highest value. And on the right is the new &quot;group
   auto-scale&quot; setting for the same RNA-seq data where all tracks are scaled against
   the one track in the region that has the highest value (67215 for IMR9 cell TAP + 1).<br>

 <strong>Vertical viewing range (boxed in red)</strong>: The min and max values specify the vertical portion of 
 the graph that is displayed (default range is 30-70). These numbers can be used to set data 
 threshold indicators. For example, to display only those GC values greater than 50 percent, set 
 the min value to &quot;50&quot;.</p> 
 <p> 
 <strong>Transform function</strong>: Transforms the data points by the function selected in the 
 drop-down menu. Usually the default setting is &quot;None&quot;.</p> 
 <p> 
 <strong>Windowing function</strong>: When a  view is too large to show individual data values, the
 values must be combined to produce a plot point. This option specifies the combining function to 
 be used (default is &quot;Mean&quot;):</p>
