Box plots in a row for multiple variables

Jazzman — Mon, 25 Apr 2016 14:34:17 GMT

Hi everybody,

I have a data file with a number of variables and I need a single graph that shows me box plots for every variable in one row so that they can be compared. I just can't find a way to realise this with the boxplot procedure. The box plots are always in separate rows and I need to specify a group variable even if I don't have separate groups.

Thanks for your help!

First off you would normalise the data needed, then graph on that. You've not posted data, so I just assume something:

ID VARA VARB VARC

1 12 56 34

...

Normalise to:

ID VAR RESULT

1 A 12

1 B 56

1 C 34

...

Then:

proc sgplot data=have;
  by id;
  vbox result / category=var;
run;

As RW9 suggests, transpose your data to long form and use the CATEGORY= option. An example in in this blog post. You can skip the steps about ordering the boxplots, unless that is something you want to incorporate.
