Customizing the width of hbar sgplot

Anita_n — Wed, 25 Oct 2017 10:43:49 GMT

I have plotted hbar chart with sgplot for different customers. The problem I have is if the plot has more than 1 bar the widths are okay but if the plot outputs only one bar the width becomes double. Is there any way I can make the width fixed no matter the number of bars created. I have already used the hbar statement barwidth=0.8 but this is not helping. I will appreciate any help. Thanks in advance

There is no way to set a fixed bar width that will apply to all cases. SG computes such things outside in, not inside out. When there is only one category, the computations are a bit different. We can look into it.

However, If you know you have a one category situation, you can try setting the offsetmin and offsetmax on the category axis to reduce the bar width. yaxis offsetmin=0.3 offsetmax=0.3;

Okay, thanks a lot. I will try that and let you know the outcome

I have the offsetmin and offsetmax set to 0.05 does that have any influence on the width of the bars?

yaxis display=(nolabel) offsetmin=0.05 offsetmax=0.05;

Hello Sanjay,

sorry I was on holidays. I came back today and tried your suggestion but it didn't work. Is there any other way I can adjust the width?

I will be glad if any one can help.

Am just thinking of using if statement. To say if number of bars less than 4 then width=? else width =?

but I haven't tried that yet.

If you share your program with sample data, it is easier for others to help. "Did not work" does not provide much information.

Hi Sanjay;

sorry for repling so late. I was a little bit busy with some other issues. Here is the code for Program. The problem is that the width decreases with the number of bars. I do not want that, I want the width to be fix no matter the number of bars. I hope you can help.

Thanks in advance

proc import datafile= "saslibrary\test1.xls" out=test
dbms=xls replace;
getnames=yes;
run;
%macro report ();
%do i = 501 %to 505 ;

proc sgplot data=test  pad=(bottom=5%);
styleattrs datacolors=(red);

yaxis grid type=discrete discreteorder=data;
 
hbar sport_typ /response=count
                   barwidth=0.8 missing datalabel = count;
      
yaxis display=(nolabel) offsetmin=0.05 offsetmax=0.05;
xaxis label='Number of Athletes' grid offsetmin=0.0 offsetmax=0.05;
where rep_id = &i;

 run;
title " ";

%end;

%mend report;
%report ();

A few things. Like in many other SAS programs, you do not need a macro. Sort your data by rep_id and use a BY statement in PROC SGPLOT instead as in this small example

proc sort data=sashelp.class;
	by sex;
run;

proc sgplot data=sashelp.class;
	by sex;
	scatter x=height y=weight;
run;

I don't think it is possible to fix a bar width, so it does not change with the number of bars in your plot. As the documentation states, the BARWIDTH statement "specifies the width of the bars as a ratio of the maximum possible width".

Please see my previous answer to this question. "There is no way to set a fixed bar width that will apply to all cases. SG computes such things outside in, not inside out." For a set graph size, the bar width will depend on the number of bars in the graph. More bars -> less bar width.
