Showing the least-squares line through a set of x,y points [message #65320]

Hi,

I was wondering if it could be possible to plot the least-squares line
for a set of points on a 2D plot for a set of x,y points. This would
involve reading the set of points via a textfile initially and then
including additional syntax that would compute the "best-fit" line
(this is correctly called the line of least-squares) through these
points. I'm well capable of doing this in Excel but have had
difficulty tracking the correct commands in IDL. Many thanks for any
help you can give me on this problem.

Thanks,
Robert.
