Hard to tell without the work.temp data to try the graph, but ...
I assume since you're using xsys/ysys=2 that you're annotating the table inside the graph axes area(?), and you don't want the annotated text to overlap with the gplot markers(?)
In axis statements, you can use the 'offset' option to add whitespace within the axes, to guarantee there will be space inside the axes that doesn't contain gplot lines/markers, and annotate the table there.
Or, I would recommend annotating the table outside the gplot axes, along the side of the graph (you'll have to use a different xsys/ysys) - you can use a fake/blank title, angled on the side of the graph, to make room for the table, such as ...
title2 angle=90 height=10pct " ";
(or use -90 for the other side)
[Note that you can't use fake blank titles like this with dev=java and activex, only with the traditional devices like gif, png, etc.]
