How to deal with overlapping values pie chart?

[marysmith]

Hello 🙂

Is there any possibility to improve my piechart figure?

Its impossible to read the values, as they are overlapping.

Thank you 🙂

PROC GCHART 
DATA=arzneimittelgruppen;
PIE category / other=0 clockwise percent=arrow;
title 'Overview of classes of drugs and treatments in post-marketing study notification 2014-2016';
RUN;
QUIT;

Not sure what to suggest other than reduce the groupings, perhaps consider a grid of x number of pie charts rather than one big one.  Also, I would highly recommend moving to sgplot/gtl.

Since your pie chart has too many slices, I don't think it make sense to use pie chart. Try alternate to Pie, descending bar chart would have better presentation for this kind of data.

If you want to stick with pie chart then try custom legend. Check this paper.
