Missing Annotation Data

I have a dataset I am trying to annotate to a PROC GCHART graphic. The annotation data ranges from 0-100% for a stacked bar graph containing two subgroups. Whenever there is a 0% present the annotated data does not display on the graph. Everything else displays fine.

 

It works just fine when all values are above 0%. My question is, how do I get annotated values to display even if no value possible on the graph? Here is my annotation code:

 

data maddr;

set WORK.MONTHLY_ADDRESS_RESULTS;

retain xsys "2" ysys "2" position "E" /*color "white" /*outline "black"*/;

size=1.2;

style="/bold";

*%system(3,2);

when="a";

midpoint=Month;

subgroup=Type;

*y=20;

if Total = 0 then Total=0; else text=left(put(Total,percent8.1));

output;

run;

Re: Missing Annotation Data

In a Gchart bar chart, if you're annotating things on the stacked bar segments (ie, subgroups), and if a subgroup has a value of zero (and the subgroup is not drawn on the chart), then how will annotate know where to draw that annotation?

 

You could perhaps modify the data a little, and if the value is 0, then make it slightly more than zero (like .00001) - then a tiny slivery of a segment would be created for it in the bar, and annotate would have something to annotate on.

 

But perhaps it would be best to re-think this, and use something other than a stacked bar chart.

Re: Missing Annotation Data

I actually received this solution from SAS support as well. Changed the zero values to 0.00001 allowed everything to display from the annotation dataset. Thanks so much for your help!
