Dear Roassal users and developers,

I'm using Roassal in Pharo 4 and want to stack visualizations, something like:

| stack1 stack2 |

stack1 := RTStackBarPlot new.
stack1 add: #(1 2 3 4).
stack1 add: #(4 3 2 1).
stack1 add: #(5 3 2 0).
stack1 build.

stack2 := RTStackBarPlot new.
stack2 add: #(2 2 3 1).
stack2 add: #(4 3 2 2).
stack2 add: #(6 1 2 0).
stack2 build.

^ (stack1 , stack2) view

or

stack1 append: stack2

is this currently possible?

Cheers

HernĂ¡n
