Ordering hbar and subgroups

Reeza — Wed, 16 Mar 2011 23:46:45 GMT

Hi All,

I'm analyzing some survey data and want to present some data in a horizontal bar chart. The data is in terms of agreement, neutral or disagreement. I can get the data in the chart but not in the order I'd like.

I would like to have the Questions order by the Agree %, so the topic that most people agree with is at the top of the charts. Second I would like the 'bars' within the questions arranged from Agree to Neutral to Disagree. I could drop the Disagree without changing the appearance, but thought I'd leave it in for now.

I'm using a sample for Rob Allisons page.

Here's what I have so far.

Thanks!
[pre]

data have;
input question $ agreement $ percent;
cards;
Q1 Agree 0.25
Q1 Neutral 0.30
Q1 Disagree 0.45
Q2 Agree 0.55
Q2 Neutral 0.10
Q2 Disagree 0.35
Q3 Agree 0.45
Q3 Neutral 0.25
Q3 Disagree 0.3
;
run;

proc sort data=have; by agreement descending percent; run;

goptions gunit=pct htitle=4 ftitle="albany amt/bold" htext=2 ftext="albany amt";

axis1 label=none;
axis2 label=none order=(0 to 1 by .1) minor=(number=1) offset=(0,0) value=(h=3pct);

legend1 label=none position=(bottom)
shape=bar(3,3) across=3;

/* pattern v=solid color=red; */
pattern1 v=solid color=cxbd0026; /* kind of a seafoam green */
pattern2 v=solid color=cxc7e9b4; /* this is the hex rgb color for mild blue */
pattern3 v=solid color=cx43a2ca; /* reddish color */

title1 "Percent Agreement";
proc gchart data=have;
hbar question / discrete
type=sum sumvar=percent
subgroup=agreement/* this controls the coloring */

maxis=axis1 /* midpoint axis */
raxis=axis2 /* response/numeric axis */

Hi.
How about this:
[pre]
data have;
input question $ agreement $ percent;
cards;
Q1 Agree 0.25
Q1 Neutral 0.30
Q1 Disagree 0.45
Q2 Agree 0.55
Q2 Neutral 0.10
Q2 Disagree 0.35
Q3 Agree 0.45
Q3 Neutral 0.25
Q3 Disagree 0.3
;
run;
[/pre]
data have;

set have;

select (question);

when('Q2') question=' Q2' ;

when( 'Q3') question= ' Q3';

when( 'Q1') qwestion='Q1';

otherwise;

end;

select (agreement);

when('Agree') agreement=' Agree' ;

when('Neutral') agreement= ' Neutral';

when('Disagree') agreement='Disagree' ;

otherwise;

end;

run;

goptions gunit=pct htitle=4 ftitle="albany

amt/bold" htext=2 ftext="albany
amt";

axis1 label=none;

axis2 label=none order=(0 to 1 by .1) minor=(number=1) offset=(0,0) value=(h=3pct);

legend1 label=none position=(bottom)

shape=bar(3,3) across=3;

/* pattern
v=solid color=red; */

pattern1 v=solid
color=cxbd0026; /* kind of a seafoam
green */

pattern2 v=solid

color=cxc7e9b4; /* this is the hex rgb
color for mild blue */

pattern3 v=solid
color=cx43a2ca; /* reddish color */

title1 "Percent Agreement";

proc gchart data=have;

hbar question / discrete

type=sum sumvar=percent

subgroup=agreement/* this controls the coloring */

nostats

maxis=axis1 /* midpoint axis */

raxis=axis2 /*
response/numeric axis */

autoref /*
reflines at every major axis tickmark
*/

legend=legend1

coutline=same

You can use numeric values for the subgroups, and assign the numbers in the order that produces the desired ordering of the stacked bar subgroups/segments.

Then use a user-defined format to cause the numbers to show up as the desired text in the legend.

Oh - and you can use the same sort of tricks to control the bar order also.

To make the question ordering data driven you can summarize, create a new variable and format as in this example. The order and format for response is also created.

[pre]
data have;
input question $ agreement $ percent;

Q1 Agree 0.25
Q1 Neutral 0.30
Q1 Disagree 0.45
Q2 Agree 0.55
Q2 Neutral 0.10
Q2 Disagree 0.35
Q3 Agree 0.45
Q3 Neutral 0.25
Q3 Disagree 0.3
Q4 Agree 0.25
Q4 Neutral 0.30
Q4 Disagree 0.45

Thanks Alll, got it working!

Add on to this question, is there an easy way (ie with the options in HBAR) to get the percentages added in to the chart or do I need to use an Annotate dataset?
