Lines of a particular slope that can be moved around

[routeram]

Hi,

Thanks John and Bernard. John, I have followed your approach and i
seems fine, though I would ideally like to do the latter part of th
approach too - making trendlines from a subset of points. I haven'
tried that as yet. I will do so and get back in case I have an
trouble.

Bernard, I did put "Excel forum help" in the subject line of my email
I am sending the file again - though I have a reasonable idea as to ho
to do it now.

Thanks again.
