How to display percentage for character strings in bar chart?

[SAS-questioner]

I have a data looks like below:

ID   sex        education        Reason1        Reason2           Reason3 
1   female         high           A                B                 C
2   male          middle          B                D                 E
3   female       college          A                B                 D

There are 6 reasons (A, B, C, D, E, F), and each person needs to select three out of the six. I want to create a bar chart to display three reasons for demographic groups. In order to make sure all three reason variables are displayed in the bar chart, I convert the data into long format, so all three reason variables were combined like below:

ID     sex      education       reason
1    female       high             A
1    female       high             B
1    female       high             C
2    male         middle           B
2    male         middle           D
2    male         middle           E
3    female       college          A
3    female       college          B
3    female       college          D

I used the code like below to generate the bar chart, so it displays the frequency of each reasons for different demographic groups:

proc sgplot data=long;
	vbar sex / group=reason groupdisplay=cluster;
	xaxis label='Sexl';
run;

However, since the group size is not balanced, I want to display percentage for each reason instead of frequency. But I am not sure how to do it, could anyone help me with it? Thank you!

Anytime you discuss percentages you always want to define which values are numerator/denominator of the value you want to display. I am not sure which you want and so it might be that additional manipulation of the data is actually needed.

However to change a plot from a frequency plot to percent may be as simple as:

proc sgplot data=long;
	vbar sex / group=reason groupdisplay=cluster
                   stat=percent
                      ;
	xaxis label='Sexl';
run;

to display the percent at the end of the bar add the DATALABEL option on the VBAR statement.

If you want the percents to be within the Group you might use:

proc sgplot data=long  pctlevel=group;
	vbar sex / group=reason groupdisplay=cluster;
	xaxis label='Sexl';
run;

If neither of those is what you expect then provide some details.
