How to produce a stacked and grouped bar-graph

deleted_user — Wed, 17 Jun 2009 13:00:12 GMT

Hi anyone,

up to now, we have a grouped bar-graph like this:

options device=javaimg gunit=pt ftext=swissl cback=white;
pattern1 value=solid color=CX113388;
pattern2 value=solid color=CX426BB3;
legend1 across=1 frame position=(top center outside) label=none value=(justify=center);

proc gchart data=work.GrundlageGrafik;
format datum ddmmyyp10.;
vbar datum / sumvar = stapel
group = gruppe
subgroup = datum
legend = legend1
patternid = subgroup sum
raxis = axis1 maxis = axis2 gaxis = axis3;
axis1 label=none minor=none;
axis2 label=none value=(tick=1 '' tick=2 '');
axis3 label=none order=('Bis 2 Tage' '3-5 Tage' '6-8 Tage' 'Aelter 8 Tage');
run;

Datalines for work.grundlageGrafik are like this:
datum: gruppe: stapel:
'03MAY2009'd 3-5 Tage 827
'03MAY2009'd 6-8 Tage 592
'03MAY2009'd Bis 2 Tage 2824
'03MAY2009'd Aelter 8 Tage 637
'03MAY2009'd 3-5 Tage 1424
'10MAY2009'd 6-8 Tage 907
'10MAY2009'd Bis 2 Tage 1475
'10MAY2009'd Aelter 8 Tage 807

Now I should produce the same bar-graph, but the bars now stacked into 3 different parts (according to new field KZ). The colour of the stacked parts of one bar could stay all the same and the parts devided by a black or white line. Also, it's possible to have the same colour for the stacked parts, but different patterns.

Datelines for the "new" work.GrundlageGrafik are like this:
datum: gruppe: stapel KU
'03MAY2009'D 3-5 Tage 248 A
'03MAY2009'D 3-5 Tage 124 B
'03MAY2009'D 3-5 Tage 24 C
'03MAY2009'd 6-8 Tage 177 A
'03MAY2009'D 6-8 Tage 88 B
'03MAY2009'D 6-8 Tage 17 C
'03MAY2009'd Bis 2 Tage 847 A
'03MAY2009'D Bis 2 Tage 423 B
'03MAY2009'd Bis 2 Tage 84 C
'03MAY2009'd Aelter 8 Tage 191 A
'03MAY2009'D Aelter 8 Tage 95 B
'03MAY2009'd Aelter 8 Tage 19 C
'10MAY2009'd 3-5 Tage 427 A
'10MAY2009'D 3-5 Tage 213 B
'10MAY2009'd 3-5 Tage 42 C
'10MAY2009'd 6-8 Tage 27 A
'10MAY2009'd 6-8 Tage 136 B
'10MAY2009'd 6-8 Tage 27 C
'10MAY2009'd Bis 2 Tage 442 A
'10MAY2009'd Bis 2 Tage 221 B
'10MAY2009'd Bis 2 Tage 44 C
'10MAY2009'd Aelter 8 Tage 24 A
'10MAY2009'd Aelter 8 Tage 121 B
'10MAY2009'd Aelter 8 Tage 24 C

Does anyone know, whether such a graph type is generally possible and if yes, how to code?

Thanks a lot for any advice!

Just to make it a little bit clearer how data is structured, here is the data step to produce the new datafile. (The old datafile is very similar, there is just no column KZ)

data GrundlageGrafik;
input datum date12. gruppe $16. stapel KZ $1.;
format datum date9.;
datalines;
'03MAY2009'D 3-5 Tage 248 A
'03MAY2009'D 3-5 Tage 124 B
'03MAY2009'D 3-5 Tage 24 C
'03MAY2009'd 6-8 Tage 177 A
'03MAY2009'D 6-8 Tage 88 B
'03MAY2009'D 6-8 Tage 17 C
'03MAY2009'd Bis 2 Tage 847 A
'03MAY2009'D Bis 2 Tage 423 B
'03MAY2009'd Bis 2 Tage 84 C
'03MAY2009'd Aelter 8 Tage 191 A
'03MAY2009'D Aelter 8 Tage 95 B
'03MAY2009'd Aelter 8 Tage 19 C
'10MAY2009'd 3-5 Tage 427 A
'10MAY2009'D 3-5 Tage 213 B
'10MAY2009'd 3-5 Tage 42 C
'10MAY2009'd 6-8 Tage 27 A
'10MAY2009'd 6-8 Tage 136 B
'10MAY2009'd 6-8 Tage 27 C
'10MAY2009'd Bis 2 Tage 442 A
'10MAY2009'd Bis 2 Tage 221 B
'10MAY2009'd Bis 2 Tage 44 C
'10MAY2009'd Aelter 8 Tage 24 A
'10MAY2009'd Aelter 8 Tage 121 B
'10MAY2009'd Aelter 8 Tage 24 C
;
run;

Not sure about what your aiming to do, but, to stack KZ, you should use the SUBGROUP options. The following modification will suffice.

proc gchart data=work.GrundlageGrafik;
format datum ddmmyyp10.;
vbar datum / sumvar = stapel
group = gruppe
subgroup = KZ /* datum */
legend = legend1
patternid = subgroup sum
raxis = axis1 maxis = axis2 gaxis = axis3;
axis1 label=none minor=none;
axis2 label=none value=(tick=1 '' tick=2 '');
axis3 label=none order=('Bis 2 Tage' '3-5 Tage' '6-8 Tage' 'Aelter 8 Tage');
run;

GROUP, will combine categories and SUBGROUP will stack values.

Is this what you want?

Check the online documentation for SAS Graph in particular for the gchart procedure:
http://support.sas.com/documentation/onlinedoc/graph/index.html

And give a look at the sample gallery:
