I have nested data with counts for each of them and I need to plot them. After some research I found sunburst chart would be a appropriate model to chart them but couldn't find any SAS procedures for it. Is there any procedures like GMAP or GCHART to program Sunburst charts ?
Also is there any other appropriate model for plotting nested data ?
Hi there is an easy treemap option in SAS VA. If you do not have that available I think you'll find some treemap options in sgplot.
See in the SAS blog Graphically speaking. There are usually some very good ideas there.
Is this the sort of chart you had in mind?
Yes Exactly... But I dont have access to SAS VA.. So is there any other way to do this ?
Thanks for the information I will look into that blog... Is it possible to create Sub-grouped donut chart for multiple level nested data ?
I do not know. I seem to remember I did create a set of pies or donuts using sgchart about 15 years ago. But I can't exactly remenber how I very seldom use pie charts anymore and for the sunflower chart I had problems seeing the use.
Have you just tried using midpoint/group and subgroup in gchart. I would prefer a treemap. There is a mosaic plot in GTL that you can try.
Statisticians use mosaic plots to display hierarchical data, although in practice it works best for three or fewer levels of nesting. PROC FREQ can display a mosaic plot automatically, The plot is often used to accompany an analysis/discussion of whether there is association between variables.
