Sure!

You need to use a RTComposer. Here is an example:

-=-=-=-=-=-=-=-=-=-=-=-=

c := RTComposer new.

stack1 := RTStackBarPlot new.

stack1 view: c view.

stack1 add: #(1 2 3 4).

stack1 add: #(4 3 2 1).

stack1 add: #(5 3 2 0).

stack1 build.

c group: 'stack1'.

c nameGroup: 'stack1' as: 'My great data set'.

stack2 := RTStackBarPlot new.

stack2 view: c view.

stack2 add: #(2 2 3 1).

stack2 add: #(4 3 2 2).

stack2 add: #(6 1 2 0).

stack2 build.

c group: 'stack2'.

c nameGroup: 'stack2' as: 'Another awesome data set'.

c layout: RTVerticalLineLayout new.

c view

-=-=-=-=-=-=-=-=-=-=-=-=

You should end up with:

Title are optional. You can remove the call of nameGroup:as: if you wish.

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

Hernán
