title: Trendline in excel on min max values
body: <p>I have series of data around 3000 rows. x values are angle, y power. So a cloud is created with max min and average values all over the place (check image attached).</p>
  <p>If I use the trend-line option of excel it draws as it should a trend line that matches the median values BUT I want to draw a trend line, on the maximum and another one on the minimum values only. Is there a way to do that?</p>
  <p>Thx</p>
