SAS Line graphs from Data in a row rather than column - sas

Question

I've searched but none of the information shows how to plot a line graph from data that is given in a row, rather than column.
I have data in this form:
Firstname Lastname Sep Oct Nov Dec Jan Feb March April May June July
There are 100 rows of data with individual people. I have to plot each graph for each individual starting from Sep To July. My output will be 100 individual graphs. I know how to plot if the data is in column, but that is not what i am given. Changing the data is going to be too much work. I do not have any sas codes for rows:
**Proc sgplot data=data1;
series x=??? ( i need mths from Sep to July here)
Series y= ?? (will be the marks from the Sep to July)
Run;**
Here is how the output should look:

Answer 1

Your table needs to be in a flat format, e.g.:
FirstName LastName Date
John Smith 01JAN2018
Jane Doe 01JAN2018
This can be done with PROC TRANSPOSE. It is best to align your dates to a specific year/date. This will maintain the correct date order. Assume that your data is for 2018.
Create sample data
data have;
length name $10.;
array months[*] Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec;
retain goal 75;
do name = 'Mark', 'Jane', 'Jake', 'John', 'Jack', 'Jill', 'Bill', 'Jerry', 'Joseph';
do i = 1 to dim(months);
months[i] = round(100*rand('uniform') );
end;
output;
end;
drop i;
run;
Solution
proc sort data=have;
by name goal;
run;
proc transpose data=have
out=have_transposed;
by name goal;
var Jan--Dec;
run;
data want;
set have_transposed;
Month = input(cats('01', _NAME_, 2018), DATE9.);
rename COL1 = Score;
format month monname3.;
drop _NAME_;
run;
proc sgplot data=want;
by name;
series x=month y=goal / name='goal' lineattrs=(color=salmon thickness=2);
series x=month y=score / name='series' lineattrs=(thickness=2);
scatter x=month y=score / markerattrs=(symbol=circlefilled) name='points';
keylegend 'series' 'goal';
run;
