Showing outliers values on a boxplot

niconegrin — Mon, 25 Jan 2016 17:43:09 GMT

Hi ! I am new in this so my question is: how do I make SAS show the values of the outliers in my boxplots?

I used the "schematic" style, is there another style in boxplots that will show it?

Thanks

Nicolas

Please show the code you are using as there are several ways to make box plots and some suggestions won't apply with your starting point.

proc boxplot data=assign1;

plot fat*trt/boxstyle=schematic;

run;

proc boxplot data=assign1;

plot rea*trt/boxstyle=schematic;

run;

proc boxplot data=assign1;

plot kph*trt/boxstyle=schematic;

run;

Thanks

Also, what version of SAS - the graphing options are changing quickly between versions.

SAS 9.4

Hi Nicolas-

I think you may be looking for BOXSTYLE=SCHEMATICIDFAR. (or SCHEMATICID)

Take a look at the last couple of boxplot examples (28.3.4) to see if this is what you want to display.

https://support.sas.com/documentation/cdl/en/statug/68162/HTML/default/viewer.htm#statug_boxplot_examples03.htm

title 'Analysis of Airline Departure Delays';
title2 'BOXSTYLE=SCHEMATICIDFAR';
proc boxplot data=Times;
   plot Delay*Day /
      boxstyle = schematicidfar
      odstitle = title
      odstitle2 = title2
      nohlabel;
   id Reason;
   label Delay = 'Delay in Minutes';
run;

Hope this helps!

Nop, it does not show the "values" but that I mean the actual figure, number, it shos the outlier OK but I actually want to show the value of that outliers (for ex. 0.62, etc).

Thanks anyway

Use the ID option to specify a variable that labels outliers when using the boxstyle =schematicid or schematicidfar. You likely want the SchematicIdFar.

Am I understanding correctly that you want the values only, no circles at the locations?

You may need an annotate dataset for that...

The circles and the values....

Thanks! I already tried the SCHEMATICID option but still shows the outlies circles (which is fine) but does not show the values the circles represent.

Thanks

Post your code and log

Re: Showing outliers values on a boxplot

niconegrin — Mon, 25 Jan 2016 20:57:30 GMT

proc boxplot data=assign1;

plot fat*trt/boxstyle=schematic;

run;

proc boxplot data=assign1;

plot rea*trt/boxstyle=schematic;

run;

proc boxplot data=assign1;

plot kph*trt/boxstyle=schematic;

run;

That's the same code you posted above, please show with the boxstyle options suggested - ID/IDFAR.

Also, log and output that isn't what you expected.

Re: Showing outliers values on a boxplot

niconegrin — Mon, 25 Jan 2016 21:05:22 GMT

proc boxplot data=assign1;

plot fat*trt/boxstyle=schematicidfar horizontal;

label;

run;

proc boxplot data=assign1;

plot rea*trt/boxstyle=schematicidfar horizontal;

run;

proc boxplot data=assign1;

plot kph*trt/boxstyle=schematicidfar horizontal;

run;

I also tried the horizontal option to see if it worked...

1. Use boxstyle=schematicID

2. Use an ID statement to specify the ID variable - you've missed this step.


data class;
set class;
if name='Alfred' then weight=200;
if name='Robert' then weight=500;
if  name='Alice' then weight=20;
run;

title;
proc boxplot data=class;
   plot weight*sex /
      boxstyle = schematicid
      ;
   id name;
run;quit;

This is @ballardw solution several response above, as well.

It seems it does not recognise "set class; as it does not turn blue...

I removed the first line. It was an error introduced by the web editor on here.

Try it again.

Do you like to use proc sgplot ?

data class;
set sashelp.class;
if name='Alfred' then weight=200;
if name='Robert' then weight=500;
if  name='Alice' then weight=20;
run;
proc sgplot data=class;
vbox weight/category=sex datalabel;
run;
