More than 255 symbol statement proc gplot

sfo — Mon, 20 Jun 2016 07:20:36 GMT

Hello,

I need to create a plot where there are more than 255 distinct subjects (like a spagethi plot i.e. all subjects overlaid on the same plot).

I am able to write a loop around the symbol statement but do not know how to run the loop for more than 255 symbols (which seems to be the limit). I am using SAS 9.2.

Thanks

Its really not a good idea. > 255 distinct lines on a graph is going to be pretty much useless to anyone looking at it as - depending on the size you give - most of the graph will be data - i.e. virtually no whitespace to show difference. Is this clinical data? If so it is normaly categorised by some grouping - e.g. treatment group (and mean), timepoint, parameter etc.

It's a shame you are using SAS 9.2, if you have access to SAS9.4M2 there is a new option in sgplot to help with this... Have a look at @Rick_SAS' recent blog post on spaghetti plots at http://blogs.sas.com/content/iml/2016/06/02/create-spaghetti-plots-in-sas.html

Kind Regards,
