proc sgplot show lines splitting graph into 4 sections?

Hi there, Is there a way to separate my graph into 4 quadrants like in the picture? I'd want the lines to go through the 50 mark on both axis.

Thank you

See if this gets you started. Feel free to ask

data have;
   do x=1 to 100;
      y=rand('integer', 0, 100);
      output;
   end;
run;

data plot;
   set have;
        if x <= 50 & y <= 50 then group=1;
   else if x >  50 & y <= 50 then group=2;
   else if x <= 50 & y >  50 then group=3;
   else if x >  50 & y >  50 then group=4;
run;

proc sgplot data=plot noautolegend;
   scatter x=x y=y / group=group markerattrs=(symbol=circlefilled size=10) colorresponse=group colormodel=(blue gold red green);
   refline 50 / axis=x lineattrs=(thickness=2 color=black);
   refline 50 / axis=y lineattrs=(thickness=2 color=black);
run;
