I post the link where in support http://support.sas.com/documentation/cdl/en/grstatproc/62603/HTML/default/viewer.htm#a003199396.htm
The code could be like this:
proc sgplot data=want; title "Stock Volume vs. Close"; vbar x/ response=volume; vline y / response=close y2axis; run;
Here it's the documentation about vline:
to change the color you should use / limitattrbs=(color=< color whatever you want>);
I hope it could hep you!

I have a couple of questions before I can answer your question:
1. What SAS version are you using?
2. When you say, "line across the mid point", are you talking about a reference line?
