Plot x-axis is not formatted

Cruise — Thu, 31 May 2018 14:40:03 GMT

Is there any way to force the plot to take up on formatting on X-axis display? I'd like to show x axis as formatted for P as a range of time periods. S=Gender and A-Age formats taken up no problem. Do you know why and how to fix it?

proc format;
value P
1976="1976-1980"
1981="1981-1985"
1986="1986-1990"
1991="1991-1995"
1996="1996-2000"
2001="2001-2005"
2006="2006-2010"
2011="2011-2015"
;
value A
0 ="0-4"
5 ="5-9"
10="10-14"
15="15-19"
20="20-24"
25="25-29"
30="30-34"
35="35-39"
40="40-44"
45="45-49"
50="50-54"
55="55-59"
60="60-64"
65="65-69"
70="70-74"
75="75-79"
80="80-84"
85="Over85"
;
value S
1="Male"
2="Female";
;
run;

ods graphics / height=800 width=1800;
proc sgpanel data=mydata(where=(A>30));
panelby S/novarname onepanel LAYOUT=panel columns=2 ROWHEADERPOS=right COLHEADERPOS=both SKIPEMPTYCELLS;

Interesting problem. There is an inconsistency in your variable names (you use X=P1 but set FORMAT P P.), but that doesn't seem to be the issue. For anyone interested in looking into this issue, here is some sample data:

data mydata;
do S = 1 to 2;
   do A = 0 to 85 by 5;
      do P = 1976 to 2011 by 5;
         rate = A + P; output;
      end;
   end;
end;
run;

ods graphics / height=800 width=1800;
proc sgpanel data=mydata(where=(A>30));
panelby S/novarname onepanel LAYOUT=panel columns=2 ROWHEADERPOS=right COLHEADERPOS=both SKIPEMPTYCELLS;
series y=rate x=P/ group=A lineattrs=(pattern=solid) lineattrs=(thickness=2);
keylegend/title="AGE GROUPS" position=right;
format A A. S S. P P.;
colaxis label='YEAR OF DIAGNOSIS' fitpolicy=rotate;
rowaxis label='INCIDENCE RATE, per 100,000' grid;
title1 "INCIDENCE RATE";
title2 "BY YEAR OF DIAGNOSIS AND AGE";
run;

I think what you want here is a VLINE chart, not a SERIES plot. The axis for the SERIES is continuous by default, which is probably why the format did not show up. Also, the nature of your format is going to require some kind of aggregation (probably mean). Try replacing the SERIES statement with this statement and see if you get what you want:

vline p / response=rate group=A stat=mean lineattrs=(pattern=solid) lineattrs=(thickness=2);

Hope this helps!

In addition to the plot type issues I think you have defined your P format incorrectly to begin with.

I think you intended

proc format;
value P
1976 - 1980="1976-1980"
<etc>

if you wanted a grouping format.

And since you seem to want to combine the values then perhaps you should do that in a separate summary procedure or data step to create the appropriate Y axis value(s) using the P format to group the years. Since you have a rate displayed you probably cannot get the graphing procedure to combine things across years correctly (averaging rates in general yield incorrect results unless the denominator is identical for each and every group of data).
