Subject:      tagging a third variable value on a proc GPLOT line..
Comments: cc: ysk <ysk.kan@gmail.com>

Hello all,

     I am trying to create a two dimensional graph using proc GPLOT .
The situation is like this :  I have two variables month and
lab_measurement (month is an independent variable on X axis and
lab_measurement  is the dependent variable  on Y axis) and i have to
plot this for a a group of patients . So the plot statement i used
was

   plot pth*dt = pid

so far so good . But now i need to add another level of complexity
here and this is where i am getting stuck . Now i need pick up another
three variables from the same data set :  death , fracture and
tranplantation . These three variables typically have the date values
. Now from the plot i created earlier for the same patients , i need
to tag these three variables on the same line that i create for each
patient in the graph . So lets say for e.g patientA had undergone a
transplantation on feb2004 then for the patientA line that was created
in the graph earlier , exactly at coordinates (month ,
lab_measurement) i need to put a symbol there , either a dot or square
or something .  or for e.g patientB died on mar2004 then for the
patientB line in the graph , exactly at the coordinates (month ,
lab_measurement ) i need to put a tag there.

      I thought of creating an annotate data set , but i didnt know
how to move it to the exact (x,Y) coordinate location for each
patient. another one i thought is superimposing the graph , but didnt
really find a clue . Since i am not well versed with the SAS/graph , i
am not able to think beyond this.

   Any help in this regard would be greatly greatly appreciated.

I hope i am clear , or if someone wants little more clarity i would be
more than happy to provide it .

Thank you
rao.
