Brackets for x axis quarters for proc sgplot

[analyst_work]

Hi, 

I am working on a bar graph in sgplot. The x-axis values currently are by Q1-2017, Q2-2017, Q3-2017, Q4-2017,  Q1-2018, Q2-2018, Q3-2018, Q4-2018. I am hoping to keep the values for Q1, Q2, Q3, Q4 and add a bracket with 2017 and 2018 below the quarter labels. Is it possible to add brackets below the x axis? Attached is the current & expected display of the x axis values.

I would use Proc SGPANEL, you will not have the brackets, but it is visually close. See example below:

data have;
  do year = 2017 to 2018;
    do qtr = 1 to 4;
      someDate = mdy(3*qtr, 1, year);
      someValue = rand("integer", 100, 500);
      qtrc = cats("Q", qtr(someDate));
      output;
    end;
  end;

  format
    someDate date9.
    someValue comma14.
  ;
run;

proc sgpanel data=have;
  where someDate > "01apr2017"d;
  panelby someDate / layout=columnlattice colheaderpos=bottom  novarname uniscale=row proportional noborder;
  vbar qtrc / response=someValue;
  colaxis display=(nolabel);
  format somedate year.;
run;

Thank you, this extremely helpful. I am able to plot the graph with panels for each year from 2017-2022 by quarter, also adding a grouping variable.

I have one follow-up question:

The code currently creates these graphs by quarter. I need to plot the data by month, but display Q1, Q2, Q3, Q4 with the panels for each year. Is that possible to do?

Here's what I have so far:

[Ksharp]

proc format;
picture fmt
low-high='9'(prefix='Q')
;
run;

data have;
call streaminit(123);
do year=2017 to 2019;
 do month=1 to 12;
   qtr=ceil(month/3);
   value=rand('integer',1,100);
   output;
 end;
end;
format qtr fmt2.;
run;


proc sgpanel data=have ;
panelby year/layout=columnlattice onepanel spacing=0 noborder
 colheaderpos=bottom  novarname;
block x=month block=qtr/FILLTYPE=ALTERNATE nooutline  transparency=0.3;
vbarparm category=month response=value;
colaxis label=' ';
rowaxis label=' ' ;
run;

Thank you so much, this worked well! I had 2 follow-up questions:

1. My data only has values till 1/2022, why does the graph display all months for 2022? Is there a way to correct this? Eventually I want to use the values & valuesdisplay options so I can specify what the values should be.
2. I want to remove the block values, but when I add novalues option to the block statement, it reverts back to default options with a warning 'Too many display features were removed from the BLOCK plot. Defaulting to standard options'. Is there any workaround for this?

Here's my code & output:

proc sgpanel data=have ;
panelby year/layout=columnlattice onepanel spacing=0 noborder
 colheaderpos=bottom  novarname;
block x=month block=qtr/nooutline nofill;
vbarparm category=month response=value/group=arm groupdisplay=cluster;
colaxis label=' ' valuesrotate=diagonal;
rowaxis label=' ' min=0 max=50;
run;

 Output:

1.My data only has values till 1/2022, why does the graph display all months for 2022?

You need add these two options.

proc format;
picture fmt
low-high='9'(prefix='Q')
;
run;

data have;
call streaminit(123);
do year=2017 to 2019;
 do month=1 to 12;
   qtr=ceil(month/3);
   value=rand('integer',1,100);
   output;
 end;
end;
format qtr fmt2.;
run;
data have;
 set have;
 if year=2019 and month in (5:12) then delete;
 run;

proc sgpanel data=have ;
panelby year/layout=columnlattice onepanel spacing=0 noborder
 colheaderpos=bottom  novarname uniscale=row PROPORTIONAL ;
block x=month block=qtr/FILLTYPE=ALTERNATE nooutline  transparency=0.3;
vbarparm category=month response=value;
colaxis label=' ';
rowaxis label=' ' ;
run;

2.I want to remove the block values, 

I didn't get any problems. I think that is because you used NOFILL option, remove it.

proc format;
picture fmt
low-high='9'(prefix='Q')
;
run;

data have;
call streaminit(123);
do year=2017 to 2019;
 do month=1 to 12;
   qtr=ceil(month/3);
   value=rand('integer',1,100);
   output;
 end;
end;
format qtr fmt2.;
run;
data have;
 set have;
 if year=2019 and month in (5:12) then delete;
 run;

proc sgpanel data=have ;
panelby year/layout=columnlattice onepanel spacing=0 noborder
 colheaderpos=bottom  novarname uniscale=row PROPORTIONAL ;
block x=month block=qtr/FILLTYPE=ALTERNATE nooutline nolabel novalues ;
vbarparm category=month response=value;
colaxis label=' ';
rowaxis label=' ' ;
run;

Thank you. When I add the uniscale and proportional options, it works fine till I add 'values' and 'valuesdisplay' options. The graph reverts back to showing data for all months for 2022. 

[BrunoMueller]

I assume the values and valuesdisplay disable the uniscale and proportional options.

Please show a mockup of what your graph should look like.

Have a go at this example, it uses two TEXT statements to "draw" the tickmarks as well as the Qn value. The BLOCK is optional.

data have;
  call streaminit(123);
  do year=2017 to 2019;
    do month=1 to 12;
      somedate = mdy(month,1,year); 
      tick = "'";
      pos_tick = 0;
      value=rand('integer',1,100);
      length qtr_c $ 2;
      qtr_c = cats("Q", ceil(month/3));
      if month in (1,4,7,10) then do;
        month2q = qtr_c;
        pos_month2q = -1;
      end;
      else do;
        call missing(month2q);
      end;
      output;
    end;
  end;
  format somedate date9.;
run;

proc sgpanel data=have noautolegend ;
  where somedate between "01jan2017"d and "01apr2019"d;
  panelby year /
    layout=columnlattice onepanel
    spacing=5 noborder
    colheaderpos=bottom  novarname
    uniscale=row proportional 
 ;
  * block x=month block=qtr_c / filltype=alternate nolabel novalues nooutline;
  vbarbasic month / response=value ;

  text x=month y=pos_tick text=tick / 
    textattrs=(color=blue ) position=bottom vcenter=bbox
