Answer 1

I just ran your code and it all works fine on my computer.

In SAS 9.2, check the Results/Explorer window and go to Results tab (the bottom of that window) and my guess is, it should created a PNG file of the plot from PROC SGPLOT.

Based on my experience, you cannot open high-resolution graphical outputs in SAS 9.2, but SAS Enterprise Guide can.
