label between bars

[Juen]

Hi SAS experts,

I try to use annotation to place a label in between two bars. But I can only put it on top of one bar, and don't know how to put it in between two bars.

In the below code, I try to place the label "p=0.001" in between bars "RC and "RF".  In another word, I try to put the label on top-middle of the the line generated by the code

function=  "polycont"; xc1="RC"; y1=49;  output;

function=  "polycont"; xc1="RF"; y1=49;  output;

I have tried to give a large value of width, it didn't work either. It always sits on top of the "RC" bar.

Can anybody help me?

I am using SAS 9.3 M1.

Thanks a lot!

Here is my code:

data bites_results;   * bites per 100 kcal;

input meal $ 1-31 diet $ 32-37 size bites bites_SE;

datalines;

                     B         RC        34      33.2941176       2.0170969

                     B         RF        23      43.2173913       2.5683976

                     B         EB        46      46.9565217       2.1526204

;

run;

data bites_results; set bites_results;

meal= compress(meal);

upper=bites + bites_SE;

lower=bites - bites_SE;

run;

data anno;

length xc1 $2;

retain drawspace "datavalue" linethickness 4;

function = "polyline"; xc1="RC"; y1= 37; output;

function=  "polycont"; xc1="RC"; y1=49;  output;

function=  "polycont"; xc1="RF"; y1=49;  output;

function=  "polycont"; xc1="RF"; y1=47;  output;

function=  "text";     xc1="RC"; y1=50; label= "p=0.001"; textsize=15;  width=100; output;

run;

proc sgplot data=bites_results sganno=anno;

vbarparm category=diet response= bites /limitupper = upper limitlower=lower LIMITATTRS=(thickness=2) ;

yaxis label="Bite Count" labelattrs=(size=20) valueattrs=(size=20) offsetmin = 0;

xaxis display=(nolabel) valueattrs=(size=20) ;

run;

To place anything on a discrete axis in a place other than the midpoint value, use the DISCRETEOFFSET attribute.  To put something halfway between A and B (adjacent values), use XC1='A' and DiscreteOffset=0.5  OR XC1='B' and DiscreteOffset= -0.5.

Thanks. It does the trick.

Below is my code just in case others may be interested.

function=  "text";

xc1="RC"; DiscreteOffset=0.5; y1=50; label= "p=0.001"; textsize=15;  width=100; output;

Thanks a lot.

FYI...It is also possible to place text in the graph using the MARKERCHAR option of the SCATTER plot.  The data can come from the procedure data set and you can use DiscreteOffset the same way.  With SAS 9.4M2, you can also use the TEXT statement.
