All:

On the Symbol statement, there is a MODE=Exclude|Include option, and the default
is Exclude. So, add Mode=Include to fix this.

I am guessing that the problem is your vaxis and haxis options. While
they might make the plot more attractive, they also cause PROC GPLOT to
ignore certain data points, and not use them in the regression if the
data point is beyond the limits of your haxis and vaxis.
