PROC SGPANEL: How to use independent Y-axis scales for different variables in a panel?

Hello everyone,

I am struggling with a visualization issue in PROC SGPANEL. I want to plot two different variables (Soil Carbon Stock and Nitrogen Stock) side-by-side.

The problem is that my Carbon values are around 80 Mg/ha, while Nitrogen values are around 7 Mg/ha. Since SGPANEL forces a uniform scale for the row, my Nitrogen bars become almost invisible.

Is there any way to force independent Y-axis scales for each panel while keeping them in the same row?

Here is a snippet of my current code:

proc sgpanel data=Tabela_modelo noautolegend;

where Variavel in ("C_stock" "N_stock");

panelby Variavel / columns=2 novarname spacing=10 onepanel uniscale=row ;

styleattrs datacolors=(CX08306B CX08519C CX2171B5 CX4292C6 CX6BAED6 CX9ECAE1);

vbarparm category=Cover_crop response=Estimate / group=Cover_crop groupdisplay=cluster;

colaxis display=(nolabel novalues);

rowaxis label="Estimate" ;

run;

Nope.
If you want "keeping them in the same row" ,then you have to plot two graph and combine them together, check this blog:

Otherwise you should stack up these two graphics to make they have Y-Axis separatedly .

An alternative way is using GTL, check PROC TEMPLATE .

proc template;
define statgraph lattice;
begingraph;
entrytitle "Car Performance Profile";
layout lattice / border=false pad=0 opaque=true
rows=1 columns=2 columngutter=3;
layout overlay;

barchart category=status1 response=value1 /yaxis=y group=status1 name="cars";

endlayout;
layout overlay;

barchart category=status2 response=value2 /yaxis=y group=status2;

endlayout;
sidebar;
discretelegend "cars";
endsidebar;
endlayout;
endgraph;
end;
run;


data Alive Dead;
 set sashelp.heart(obs=200 keep=status sex weight height);
 if status='Alive' then output Alive;
  else output Dead;
run;
data have;
 merge  alive(rename=(sex=status1 weight=value1))  dead(rename=(sex=status2 height=value2));
run;

proc sgrender data=have
template=lattice;
run;
