trend line over multiple scatter plots [closed]
I have data and a graph made from that data as such:
I would like to have best fit curves/lines for each of the tests in the graphs. When I double click on the chart and hit insert, the trend line is disabled.
This is the file am trying to get to work. Specifically it is the last sheet "Summary of all tests"
Could you share test file without any personal or sensitive info (check File → Properties) so that it's not needed to recreate data and graph from scratch just for sake of checking what might be wrong? Thanks
@Kruno, I added the file I an trying to get to work. There is no sensitive info, just data that is dumped from the program, its the program that generates the data that I cannot share, I see no harm in sharing this.
