The "other=1" option would group any slice less than 1% into an 'other' slice, and I presume since value of zero is less than 1% of the pie, it is going into 'other' ... and then since the 'other' slice is 0% of the pie, gchart is not showing it.   To have this pie slice show up, you could set it to a very small non-zero value (such as .00001) and then use other=0 (so the slice doesn't get lumped into an 'other' slice). I'm not sure it's a good idea to have such a pie ... but this is one way to visually produce what you're asking for 🙂   data test; input province $ amount; datalines; AA 20 BB 0.00001 ; run; PROC GCHART DATA=test; PIE province / sumvar=amount angle=90 other=0 legend=outside midpoints=old TYPE=SUM value=none PERCENT=arrow slice=arrow noheading plabel=(font='albany AMT/bold' h=1.3 color=crimson); run;   ...
