display value of segments and y axis grid in stacked bar chart

[dr2014]

Hi all,

I am creating a stacked bar chart for percent scored on test which is categorized in difefrent groups as low , midddle and high. Below is the data and my code. The 'Score' variable is in percent.

(1)  I need to reduce the width of the bar and

(2) also add 'Score' of the 'Category' to each segment in the bars.

(3) Remove the word 'Category' on the legend.

(4) adjust the percent 'interval' on the y-axis and add the symbol % next to the numbes on the grid lines. Please advise as soon as possible. Thanks.

proc sgplot data=want;

title 'Distribution XXXXX;

vbar Test / response=value group=Category;

xaxis display=(nolabel);

yaxis grid label='Percent %';

run;

Category	Test	Score
low	CHE	11
middle	CHE	83
high	CHE	3
low	PHY	7
middle	PHY	54
high	PHY	38
low	MAT	10
middle	MAT	69
high	MAT	19
low	BIO	16
middle	BIO	33
high	BIO	51

Addtionally, when I output the chart I get a inner and outer box. Is there a way to get rid of it?

Thanks.
