### sas >> SAS Graph: Getting sub-percents on a stacked bar graph

Hello Eveyone,
=A0
I am trying to create a stacked bar grpah with subpercents. The graph lists=
the number of chemotherapy cycles patients received by whether or not they=
have completed treatment. There are 32=A0patients, 16 of whom have complet=
ed treatment and 16 of whom have not.
=A0
My code is pasted below.=20
=A0
I would like to get the overall percents at the top of each bar (i.e., in t=
he outside =3D position) and the subpercents=A0within the segments of each =
bar (i.e., in the inside=3D position).=A0For example,=A0I have a total of 6=
patients who have undergone=A02 cycles of treatment. Four patients have co=
mpleted treatment and two patients are still on treatment. Thus, the overal=
l percent for this bar should be 18.75% (6/32) and the two inside percents =
should be 12.5% (2/16)=A0and 25.0% (4/16)=A0respectively.=20
=A0
Getting the outside percent to display correctly is no problem but=A0gettin=
g the inside percents is proving to be much more difficult.
=A0
Can anyone show me how to get the inside percents?
=A0
A couple of additional questions arose as I was trying to figure out how to=
make this graph.
The first concerns how to draw an appropriately sized box around the legend=
.=A0In my code, I can use /*cborder=3Dblack*/ to=A0draw a box. However, the=
box is far too wide and, in the end, I wound up using an annotate dataset =
to draw the box.=20
=A0
Is there a way to control the size of the box around the legend without res=
orting to the use of an annotate dataset?
=A0
Finally, I also had the idea of just drawing the percent values on the bars=
using something like:
=A0
note height =3D 0.75 j =3D left
move =3D (10, 15) "(12.50%)";
=A0
The problem is that SAS puts the text behinnd the bars instead of in front =
so that they cannot be seen. I looked but was unable to find a command that=
would enable me to bring the text to the foreground.
=A0
Can anyone show me how to do this?

```When creating a bar chart, how can I display the bar statistic value at the=
end of the bar?

I've tried the BARCHART statement's BARLABEL option, but it generates an er=
ror when running PROC TEMPLATE.

Thanks,

```Hi All,

Is it possible to color only one bar out of the other in a different
color?? I have all Asia pacific countries BAR, plus a AP Region
bar(computed). I wann to show the AP region Bar in a Diffrent color.

Also, I've arranged the BARS in ascending order. Is it possible to have
all countries bars ascending , and a final bar for the AP
region(irrespective of its value).

any help will be helpful!! :)

Thanks

```Hi All,

I am trying to annotate a vertical bar chart with within subgroup
percentages. I have tried unsuccessfully using the INSIDE= & OUTSIDE=
options within VBAR statement to get SAS to automatically print the subgroup
% either inside the bars or outside. However I get an error message noting
that the bar width is insufficient. I have tried different spacing criteria
to no avail.

This is possibly because I am graphing 11 groups with two bars within each
group 9 thus a total of 22 bars on the x axis). The individual bars are
further subgrouped according to another binary variable, whose % I am trying
to obtain on the graph.

Another approach I tried was to use the SAS ANNOTATE facility to annotate
the subgroups. There is an example program on SAS website which shows how to
annotate subgroups of vertical bar charts. I tried to using this example to
fix my graph. However I can't get it to print the %. Instead it prints the
binary value of the subgroup variable in the sub-bar ( i.e 1 or 0). I am
trying to get SAS to print the percentage of 1's & 0's.

Any help is appreciated.

Thanks much,
Jasmine

Below you will find the code I am using -

To create the annotate dataset :
*

data* barlabel;

length color style \$ *8*;

retain color 'red' when 'a' style 'swiss'

xsys ysys '2' position 'E' size *3* hsys '3';

set chart;

midpoint=TRT;

group = VISIT;

subgroup=SCORE;   /* SCORE is abinary variable 0/1 */;

text=left(put(subgroup,*5.*));   -----> This just puts the value      of the
corresponding subgroup 0/1 in the subgroup bars ( this probably needs some
tweaking inorder to get SAS to produce percentages ??? )
*

run*;
*

proc* *gchart* data=chart;

vbar TRT /

discrete

subgroup = SCORE

group = VISIT /* specify group variable */

width = *3* /* specify bar width */

gspace = *2* /* specify space between groups */

type= pct /* specify type of statistic */

g100 /* specify within group pct calculation*/

maxis = axis1 /* assign midpoint axis options */

gaxis = axis2 /* assign group axis options */

raxis = axis3 /* assigns response axis options*/

legend = legend1

annotate = barlabel

;
*

run*;
```

```Hi all,

What I want to do is pretty simple, but I don't know off hand how to do it
in SAS or if it can be done.  I am plotting some data to go along with a
simple one way ANOVA.  The dep variable is on the Y axis and the treatment
groups (group 1, group2,.., group 8) are on the x axis.  What I want to do
is to plot the means of each group with error bars above and below.  On the
error bars I want to put the upper and lower limits of the confidence
interval for each mean.  Is there any way to do this?

Thanks so much for your help!
