Sgplot : How to use variable name of variable name in diagram

Sathish_jammy — Fri, 29 Mar 2019 11:01:08 GMT

Hi Experts,

I share the Image of my table as well in the dataset format.

First please have a look at my images (Excel, sgplot) I want my diagram in the given format

data aaa;
input Age_Bins$ SysBP Dia_BP SysBP_M DiaBP_M;
cards;
20-29 199.8 82 116.3 76.9
30-39 134 88.4 119.3 78.3
40-49 135.2 85.5 121.4 79.9
50-59 141.3 82.6 124.6 80.7
60-69 142.7 79.4 128.4 81.4
70-80 148.9 82.6 132.8 81.4
;

Proc sgplot data=aaa;
   reg x=Age_Bins y=DiaBP;
	reg x=Age_Bins y=DiaBP_M; 
run;

Using the above code I draw a sgplot.

But I don't know how to put the group (INDIAB, MDRF), and the value of plot points in sgplot.

My expected plot which look like : (Sample)

Please suggest me some ideas to solve this method.

Thanks in advance!

Please provide data step AND proc step that actually generate your output. The data step does not have a variable DIABP mentioned in the SGPLOT code. I assumed that should have been DIA_BP. However your X variable AGE_BINS is character in the data set and you can't use a character variable for regression.

Also you mention "group (INDIAB, MDRF),". There are no variables or data values of those so where are we supposed to get that information. We need those variables, or the variable with those values in the data step.

Typically to get SGPLOT to do something similar to your desired graph you would be plotting a single y variable with a group variable that indicates which group of data each record comes from. IF dia_BP is supposed to be the INDIAB group and DIABP_M is supposed to be from the MDRF group then your data needs to be restructured to have a variable holding the group:

data aaa;
input Age_Bins  SysBP Dia_BP SysBP_M DiaBP_M;
cards;
20 199.8 82 116.3 76.9
30 134 88.4 119.3 78.3
40 135.2 85.5 121.4 79.9
50 141.3 82.6 124.6 80.7
60 142.7 79.4 128.4 81.4
70 148.9 82.6 132.8 81.4
;
run;

data want;
   set aaa;
   SysBP=SysBP   ; DiaBP=Dia_bp; pop="INDIAB"; output;
   SysBP=SysBP_M; DiaBP=DiaBP_M; pop="MDRF"; output;
   keep age_bins sysbp diabp pop;
run;


Proc sgplot data=want;
   reg x=Age_Bins y=DiaBP/ group=pop datalabel;
   label pop='Data';

run;

You would need a custom format to apply the labels to the X axis values as ranges. I leave that as an exercise for the interested reader.

Instructions here: https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-data-AKA-generate/ta-p/258712 will show how to turn an existing SAS data set into data step code that can be pasted into a forum code box using the {i} icon or attached as text to show exactly what you have and that we can test code against.

Dear @sbxkoenk @ballardw

Thank you so much for your suggestions. Your code works well... I worked on both of your codes its wondering...

Everything is perfect except the LABEL description...

I can't see that LABEL - DATA at the bottom of the plot which we used a group in sgplot...

( Data : x Dia_BP o DiaBP_M ) ????????

If you use a 'scatter' plot instead of a 'reg' plot, it will have an automatic legend at the bottom:

data aaa;
input Age_Bins$ SysBP Dia_BP SysBP_M DiaBP_M;
cards;
20-29 199.8 82 116.3 76.9
30-39 134 88.4 119.3 78.3
40-49 135.2 85.5 121.4 79.9
50-59 141.3 82.6 124.6 80.7
60-69 142.7 79.4 128.4 81.4
70-80 148.9 82.6 132.8 81.4
;
run;

title1 "Whatever title you want";
Proc sgplot data=aaa;
scatter x=Age_Bins y=Dia_BP / datalabel=Dia_BP;
scatter x=Age_Bins y=DiaBP_M / datalabel=DiaBP_M;
keylegend / title='Data:';
run;

This too works Perfectly... for label change options...

Proc sgplot data=aaa;
scatter x=Age_Bins y=SysBP / datalabel=SysBP LEGENDLABEL = 'INDIAB' markerattrs=(symbol=CircleFilled size=10);
scatter x=Age_Bins y=SysBP_M / datalabel=SysBP_M LEGENDLABEL = 'MDRF' markerattrs=(symbol=CircleFilled size=10);
YAXIS LABEL = 'SysBP';
run;
