Hi all,


   I have the following code that correctly produced three histograms by group.

However, I would

1) like to change the color of the bars (fill black)

2) change the x axis label from Npo_mean to Hours NPO:.

3) Change and clarify the Y-axis group labels


The graph output is attached below as well


proc univariate data=tube.survival2;


  class npogroup ;

  var Hours;      /* computes descriptive statisitcs */

  histogram Hours  / odstitle="Distribution of NPO by Fasting Category"

 vscale=percent vaxis=0 to 60 by 10 normal 

 nrows=3 midpoints=(0 to 22 by 2) ;


  ods select histogram; /* display on the histograms */

  INSET N = 'Number of patients' MEDIAN  MEAN  /position=ne ;

If the histogram(s) is all you are interested in, I suggest you use PROC SGPLOT/SGPANEL instead. Gives you more control over the visual attributes of the plot.

Would you know the code to reproduce what I did above for sgplot?

I can't see your data, but this should get you in the right direction. 


title 'Your Title Here';
proc sgpanel data=sashelp.iris noautolegend;
   panelby Species / columns=1;
   histogram SepalLength / fillattrs=(color=green);
   density SepalLength / lineattrs=(color=black);
   colaxis label='Label Here';

You can find all the information you need in the PROC SGPANEL Documentation.
