When performing a Linear Regression on a graph, how do I specify that I want the line to extend all the way to the axis?

Hi Bstrap,

You can set the "X Data Type> Range" option node to "Span to Full Axis Range" (Or Custom to set more details) in the "Linear Fit" tool as sown below:

1. Expand the 'Fitted Curves Plot' branch in the Linear Fit dialog.
2. Under 'X Data Type' you will see a 'Range' option.
3. Set that to 'Span to Full Axis Range'

Thank you very much, that helped immensely.

It's easy to get lost in that tree of options. :)
