The Category list is in Chinese, so I cannot select a value meaningfully, and I cannot submit this without selecting a Category, so the Category is likely wrong. Please change it to be appropriate: I cannot do this.
I have acoustic data in one column, and have graphed that data. I also created a trend line using moving averages. I would like the data that is represented by the trend line to be exported into a different column so that I can use it, but I cannot find any way to do this.
Many articles talk about copying the trend line formula, but I do not see how there is a simple formula (such as for a linear regression) in this case.
Thanks
Jon
