I was curious if anyone had a link to a FEX to what I'm pretty sure is a common query. I have a figure which I would like to draw a line on - I pick two points using ginput, and using those those two points I create a line through them which stretches across the entire figure. This portion works perfectly, but what I need is some way to show a 'temporary' line after picking the first point. Right now I'm creating my line almost blindly based on a few landmarks, but it's difficult to remember where the first point has been placed and a 'guide' or 'temporary line' would be ideal to have after choosing the first point.
I appreciate the help, I haven't been able to find anything worthwhile through google searches and browsing through the FEX.
