Mixing a stacked graph bar with non-stacked bars on the side

[Adam Sadi]

Hi,

Is this possible to do so? I would like to measure wealth for individuals with 3 bars for each category: financial wealth, real estate, firms. But I would like to also decompose the financial wealth by many different financial assets by stacking all the financial asset variables together. The rest of the bars should be side by side.

I cannot access my data yet so I can't provide an accurate example, but any silly example from sysuse auto will suffice for me to extend it.

You can do almost anything of the kind as long as you use some combination of twoway bar and twoway rbar. Just note that graph bar is not a good place to start.

[Nick Cox]

Here is the simplest example I could think up that shows the main tricks so far as I know them.

* Example generated by -dataex-. For more info, type help dataex
clear
input float(x y1 y2 y3)
1 1 2 3
2 4 5 6
end

gen Y12 = y1 + y2 
gen xL = x - 0.2 
gen xR = x + 0.2 

twoway bar y3 xR, base(0) barw(0.4) ///
|| bar y1 xL, barw(0.4) ///
|| rbar y1 Y12 xL, barw(0.4)  ///
legend(order(2 "y1" 3 "y2" 1 "y3" )) xtitle(better text needed here) ytitle("y goes on the y axis, but explain more") xla(1 2)

So, we want to stack y1 and y2 but plot y3 by itself w.r.t. x.

We usually need to

* calculate cumulative sum variables for rbar in advance of the graph call

* arrange an offset in advance and control bar width for side by side displays.

Otherwise put, graph bar will do those for us, but twoway won't.
