Question on Proc kde: How to change axes labels

[bneuner]

Hello,

I am using SAS UE and could not manage to change the axes labels in a surface plot (Proc kde). The variable Immo_rev has two stages '1' and '2', with meaning 'immortalized'  and 'not immortalized' but SAS, by default, labels the axis 0.5 / 1.5 / and 2.5.

I tried using Proc format to give labels for Immo_rev, but these did not appear in the surface plot.

Is this an issue of SAS UE or an issue of Proc kde? In other words: what am i doing wrong and how to modify the axes labels in a density plot?

Thank you in advance,

Bruno

********** SAS-code:

proc format;
value Immo_rev
1 = ‘Immortalization’
2 = ‘No Immortalization’;
run;

ods graphics on;

proc kde data=data;
format Immo_rev Immo_rev.;
bivar distance  Immo_rev / plots = surface ;

* axis1 order=(1 to 2 by 1 value=(height=2) label=(height=2 'Immortalization status'); * one attempt that failed ;
run;

quit;
ods graphics off;

PROC KDE assumes that both variables are continuous. If Immo_rev is binary, then it doesn't have a continuous density.  I suggest you plot the univariate density of Distance for both levels of Immo_rev. You can do this by using PROC UNIVARIATE or by using PROC SGPLOT, as follows:

proc univariate data=data;
format Immo_rev Immo_rev.;
class Immo_rev;
var distance;
histogram distance / kernel;
run;

proc sgplot data=data;
format Immo_rev Immo_rev.;
density distance / type=kernel group=Immo_rev;
run;
