I would like to creat a "box-plot like" graph with summary statistical ouptut. I would like to be able to specify the box and whisker source data and wonder if there is ANY way in sgplot to do this?
Yes, use PROC BOXPLOT. There is a standard format for a data set that specifies the values for the box, whiskers, and outliers. Study this example to see the format of the BOX= data set, which can be used to create a box plot from any summary statistics:
/* SGPLOT version */
proc sgplot data=sashelp.cars;
vbox mpg_city / category=Origin;
run;
/* to use PROC BOXPLOT, sort by the categorical variable */
proc sort data=sashelp.cars out=cars(keep=Origin mpg_city);
by Origin;
run;
/* Use PROC BOXPLOT to output the values for the schematic box plot */
proc boxplot data=cars;
plot MPG_CITY*Origin / boxstyle=schematic outbox=Box;
run;
proc print data=Box;
run;
/* create box plot from input data set */
proc boxplot box=Box;
plot MPG_CITY*Origin / boxstyle=schematic;
run;
Here's the doc for PROC BOXPLOT and the input data set: SAS Help Center: Input Data Sets
Although I suggest PROC BOXPLOT, you can also use PROC SGPLOT. See this article: Annotate features of a schematic box plot in SGPLOT - The DO Loop (sas.com)
I don't see it in SGPLOT. But it's available in GTL, so you could write the template then use SGRENDER to make the plot. https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/grstatgraph/p1db7ll5bzyo4nn1pv31g04etput.htm
You might provide some example data in the form of working data step code that want to display and a description of what to do with each value.
You can use a POLYGON statement to create a box and and the HighLow to create whiskers. But you are going to have to provide a lot of explicit values in variables.
Multiple plot statements in the same call to Proc Sgplot (or sgpanel) will overlay plots within limits
I would like to plot something like the attached figure but with the ability to specifiy the parameter that determin box size, mean, and whisker min/max based on an output dataset (see attache example).

Thank you @Rick_SAS! I ended up studying the box= dataset, formatting my data accordingly, and then using proc sgpanel as I am more familiar with manipulating the visuals in sgpanel. I think that the results turned out fantastic!
proc sgpanel data=fig1 noautolegend sganno=anno;
panelby dpt / rows=2 columns=1 novarname uniscale=column;
vbox _value_ / group=sys nomean lineattrs=(color=black) medianattrs=(color=black) whiskerattrs=(color=black) capshape=none;
refline 0 / lineattrs=(color=crimson);
rowaxis label=" " offsetmax=.1;
keylegend / title=" " position=bottom noborder;
run;
As I mentioned, the BOXPLOTPARM statement in GTL allows you to generate a boxplot from summary statistics.
So given summary statistics for two treatment groups:
data have ;
input trt stat : $12. value ;
cards ;
1 min 0
1 Q1 10
1 median 20
1 Q3 30
1 max 40
2 min 20
2 Q1 30
2 median 40
2 Q3 50
2 max 60
;
You can plot it with :
proc template; define statgraph boxplotparm1; begingraph; layout overlay; boxplotparm y=value x=trt stat=stat; endlayout; endgraph; end; run; proc sgrender data=have template=boxplotparm1; run;
And you get:
You can add a legend and coloring by group and all that sort of stuff.
I know Rick Quantin have already posted the solution. Here I just would like to show PROC SGPLOT solution to have some fun.
data have ;
input trt stat : $12. value ;
cards ;
1 min 0
1 Q1 10
1 median 20
1 Q3 30
1 max 40
2 min 20
2 Q1 30
2 median 40
2 Q3 50
2 max 60
;
proc transpose data=have out=want;
by trt;
var value;
id stat;
run;
proc sgplot data=want noautolegend;
highlow x=trt low=Q1 high=Q3/type=bar barwidth=0.4 fillattrs=(color=cxBBC2DC) lineattrs=(color=black);
highlow x=trt low=min high=min/type=bar barwidth=0.2 lineattrs=graphdata1 nofill;

yaxis label='value';
run;
