Subject:      Hysteresis plots with SAS

Dear SAS-Lers,

I can very easily produce a line plot with x (for x-axis) and y (for
y-axis). But I have not successfully made a hysteresis plot with the
following fake data:

subject time  x     y
1        1   3.5    55
1        2   7.5    50
1        3   7.8    55
1        4   6.0    58
1        6   3.0    45
1        8   1.5    60

The key of the hysteresis plot is that the line connecting the points of x
and y should be in the ascending order of time (e.g. 1 to 8 hours).
However, the time should not be presented in the plot as the third
dimension.  Does anyone overthere have any luck with this kind of plots?
Please give me some help if so!!!

Thanks a lot in advance!

James
