PROC SGSCATTER: MATRIX plot is missing tick values when used with option DIOGANAL=(histogram)

[A_Kh]

Hello Community, 

While creating matrix plot using the option DIOGANAL=(histogram), tick values are disappearing . Trying to use GTL to modify the template, but don't see any available options in the tmplout-generated code or sas documentations. TEMPLATES with/out tick values don't differ. 
Is there any SG or GTL option available for the MATRIX statement to display tick values even when using DIOGANAL=(histogram) option? 

Please see the below examples.  

1. Tick values displayed without DIOGANAL=(histogram) option. 

proc sgscatter data=sashelp.iris tmplout='C:\Users\Desktop\matrix1.sas';
  title "Scatterplot Matrix for Iris Data";
  matrix sepallength petallength;
run;
title;

the tmplout created template is:

proc template;
define statgraph sgscatter;
begingraph / designwidth=640 designheight=640;
EntryTitle "Scatterplot Matrix for Iris Data" /;
layout lattice / pad=(top=5);
    ScatterPlotMatrix SepalLength PetalLength / subpixel=off NAME="MATRIX";
endlayout;
endgraph;
end;
run;

2. Tick values disappeared with DIOGANAL=(histogram) option. 

proc sgscatter data=sashelp.iris tmplout='C:\Users\Desktop\matrix2.sas';
  title "Scatterplot Matrix for Iris Data";
  matrix sepallength petallength/diagonal=(histogram);
run;
title;

the tmplout created template is:

proc template;
define statgraph sgscatter;
begingraph / designwidth=640 designheight=640 subpixel=on;
EntryTitle "Scatterplot Matrix for Iris Data" /;
layout lattice / pad=(top=5);
    ScatterPlotMatrix SepalLength PetalLength / subpixel=off NAME="MATRIX" diagonal=( histogram );
endlayout;
endgraph;
end;
run;

Unfortunately, there is not a good way to achieve what you requested. The histograms have different axis ranges from the scatter plots, so the unified external row/column axes around the matrix cannot be created without negatively impacting the visual. The best you could do would be to create a Layout Lattice in GTL and, using internal axes, add the scatter plots and histograms in the desired order.
