You could use a Cross tabs query to get your result.

SELECT CONVERT(varchar(8), DATEADD(hh, onhour, 0), 108) + ' - ' 
       + CONVERT(varchar(8), DATEADD(hh, onhour+1, 0), 108) AS Hour, 
       Sum(totals)                  AS Total, 
       Avg(CASE WHEN DayOfWeek = 'Monday'    THEN totals END) AS Monday  , 
       Avg(CASE WHEN dayofweek = 'Tuesday'   THEN totals END) AS Tuesday , 
       Avg(CASE WHEN dayofweek = 'Wednesday' THEN totals END) AS Wednesday, 
       Avg(CASE WHEN dayofweek = 'Thursday'  THEN totals END) AS Thursday, 
       Avg(CASE WHEN dayofweek = 'Friday'    THEN totals END) AS Friday  , 
       Avg(CASE WHEN dayofweek = 'Saturday'  THEN totals END) AS Saturday, 
       Avg(CASE WHEN dayofweek = 'Sunday'    THEN totals END) AS Sunday
FROM   (SELECT Datename(weekday, D.fordate) AS DayOfWeek, 
               H.onhour, 
               Isnull(T.totals, 0)          AS Totals 
        FROM   (SELECT DISTINCT T.fordate 
                FROM   #visit AS T) AS D 
               CROSS apply (VALUES(0),
