Hi All,
Fast question about a linear regression plot. If I have a hypothetical data set x = 1,2,3,4,5 and y = 1,2,3,4,5
How can I get the fitted line to extend back to the y-intercept (not a fixed intercept) as well as extend out past the plotted data?
I'd appreciate any suggestions.
Cheers!

Another question regarding the same topic: When I plot a linear regression to a graph the first and last datapoint is equipped with some sort of error bar (purple in the picture below). First of all I don't know what value they are supposed to repressend and second I'm not able to get rid of them. If I right click them and choose delete, the whole linear regression plot is deleted.

Hi,
Those are called "Analysis Markers" and they indicate the range of data that has been analyzed. They are more useful perhaps if a part of the dataset is analyzed, and not when the entire dataset is analyzed.
With the graph active, you can go to the "Data->Analysis Markers" menu item and just hide them or set them to show only for partial range etc.
