  <p>(Edited to paste code above)</p>
  <p>Can anyone tell me what the shaded area represents on my line graph (see screenshot)? The middle line represents the mean. I haven't specifically added it. I would like to know first what it is and secondly how to remove it (I might chose to keep it if I find out what it represents and it adds value to my visualisation).</p>
  <p>Any related answers I've come across don't del with this directly. Thansk in advance.</p>
