Hi, I've got a set of xy data with uncorrelated errors in x and in y. I'm using fitexy to fit a line through the data. I need to force the fit to pass through the origin. I can kludge this by adding a data point that is 0, 0 with 0 error in x and y, and this works when the errors in the other points are large, but it doesn't work when they are small. Anyone know a better way? Thanks! Barbara bcohen@hawaii.edu
