Stacked bar chart for panel data

[Junran Cao]

Hi Statalist

My question is about creating a stacked bar chart for panel data. To illustrate:

. webuse citytemp

## the rest of the code is to create a made-up panel data
. generate id = _n
. generate year = 2000
. expand 4
. bysort id: replace year = year + _n

From this I want to see the changing composition of, say, the various regions over time (it doesn't change in this made-up example but in my actual dataset there are differences over time).

. tabulate region year, column nofreq

    Census |                    year
    Region |      2001       2002       2003       2004 |     Total
-----------+--------------------------------------------+----------
        NE |     17.36      17.36      17.36      17.36 |     17.36
   N Cntrl |     29.71      29.71      29.71      29.71 |     29.71
     South |     26.15      26.15      26.15      26.15 |     26.15
      West |     26.78      26.78      26.78      26.78 |     26.78
-----------+--------------------------------------------+----------
     Total |    100.00     100.00     100.00     100.00 |    100.00

Question: What I would like to do is to graph the above two-way tabulation table like the following using Stata.

The code I tried so far is

. graph hbar region, over(year) stack percent

which doesn't work. Any suggestions would be greatly appreciated.

Thanks

The -catplot- command seems to have done the trick.

. catplot region, over(year) stack percent asyvars

But if anyone can suggest a way to replicate this graph using the official Stata commands, that would be great.
