SGPanel move axis labels

[akaranevich]

I am trying to produce a 2x2 set of bar plots that has either the axis labels both on top and bottom, or in-between the two rows of plots. I am using SGPanel, and can't seem to find a way to move the axis which labels the individual bars anywhere. I would rather not use a colored legend because some of the groups have extremely low counts, and I want them to all be on the same y-scale. 

I'm currently using the following code

proc sgpanel data=freqmed (where=(dx ^=""));
	title "Medications taken at baseline";
	format  tablenum tablenum.;
	panelby dx / novarname ;
	rowaxis label="Baseline totals";
	colaxis grid label=" ";
	vbar Tablenum / response=Frequency group=tablenum dataskin=sheen nostatlabel;
	keylegend "doesn't matter what's here it's invisible!" / title="";
run;

to produce  the following figure

but would like to make something more like the following:

I think this would be possible by

1) suppressing the actual tick labels of the xaxis and

2) adding y values to your data with  the text you want to display near the top of the panel using a text plot for the groups displayed in the bottom two panels (DX = Other and PLS).

You would likely get to experiment with the ROTATE option to get best appearance
