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).
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?
Thx
Add the Min and the Max values to the chart as new series. Add a trend line for each of these series.
Next, format the data series for Min and Max to have no fill, no line, no markers, so they become invisible and don't upset your chart display. That leaves only the trendlines visible.
