Subject:      how to know the observations on a contour plot
Content-Type: text/plain; charset=gb2312; format=flowed

Hi all experts:
a contour plot about x*y=z has been generated. Now the problem is how to
get the x and y values for a specific point on the contour plot, such as
the extreme points of the principle axis of an ellipse which is a specific
level of the contour plot?
I have tried SAS/INSIGHT, and tried to set up specific values for the
contour levels. But SAS still use its default level values.
Or, is it possible to import the prior generated contour plots into
SAS/INSIGHT, and use the observations to get the x and y value for specific
point on the plot?
Is there anyone who knows how to realize this function?
Thanks in advance!

Best wishes
Zhongmiao
