Manually draw line in log space then have excel generate a power function for it!

[pablosaso]

Hiya.

This is a weird one. I need to draw manually a line on a log plot and then have excel generate a power equation to define the line. Ideally I could do multiple equations for different lines on the plot. I will also have a bunch of points displayed on the graph that I will be viewing to guide my line drawing.

Thank you!
