You want the average-calculating to start when the first graph gets its first non-unknown value. So, If the first non-unknown value will only start after 1/4 of the time in the graph, the average will be calculated over the remaining 3/4 of the time. If you do not want that (but you want to start the average-calculating on the start of the graph), you could just take the same CDEF as the nice-line-graph, thus bringing you back in the same position as where you began. I hope this helps...
