Line graph by group and percentage

[monday89]

I have the following data.

I would like to create line graph by group and percent by group

Sample dataset:

ID	group	event_days
1	group_2	32
2	group_1	26
2	group_4	27
3	group_1	26
3	group_2	17
3	group_3	20
4	group_2	17
4	group_3	19
5	group_3	14
6	group_2	32
6	group_3	12

Output [this data won't match]

proc gplot data=sample;                                                                                                                 
   plot (yvar1 yvar2 yvar3)*xvar / overlay legend=legend1                                                                               
                                   haxis=axis1 vaxis=axis2;                                                                             
run;                                                                                                                                    
quit;     

I am not sure how to do percentage first??

Percentage of what? Total number of event days? Percent change between groups? Ids? Need to know what the numerator and denominator for each value would be.

You will have to calculate the desired percentage prior to graphing.

And time to move to SGPLOT instead of Gplot. Which might look something like this after you add the appropriate percentage value.

proc sgplot data=have;
   series x=event_days y=percent/group=group   markers;
run;

Percentage of what? Please explain how to take the sample data you show and turn it into percentages.
