To create Histogram in SAS-9.2

I want to create a histogram. Generally histogram gives counts/ frequency on the Y-axis and the variable on the histogram statement in Proc univariate on Y-axis. I was given a specific period(1 year) and asked to create a histogram for the length of stay(days) for the particular diagnosis code. There might be many patients with the same code in that year and have different length of stay as shown.

code LOStay month

500 3 feb11

500 6 mar12

501 2 apr11

501 1 aug11

501 1 sep11

501 5 jun11

thousands of data

I want to create a seperate histogram for each code.

i seperated each code into a seperate data set and did a proc univariate.

on x-axis i got LOS and on Y-axis i got percent

IS THERE A POSSIBILITY TO GET a histogram with MONTH ON X-axis and LOS days for a particular code on y-axis??????????

Thanks in advance

It sounds like you may want either PROC GCHART or SGPLOT.

And if you sort your data by the code, use a BY CODE statement to generate multiple plots instead of many datasets and calls to the proc.
