Hi Alexandre!
Thank you so much for your answer. I will explore how to best approach that behaviour to my live model.
thanks again!

Hi Agustin!
You are very welcome!
Yes, you need to recreate a new PieChart. But this is easy and efficient. Try the following:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "We create an empty view. The view will contain the button and the pie." view := RTView new.
"fillView is block that: (i) remove all the elements in the view (except the button); (ii) create a new pie with totally random data (iii) force a screen refresh with #signalUpdate" fillView := [ | b | view clean. b := RTPieBuilder new.
"The RTPieBuilder will create the pie in the view" b view: view. b interaction popup. b objects: ((1 to: 10 atRandom) collect: [ :i | 30 atRandom ]). b slice: [ :aNumber | aNumber ]. b normalizer distinctColor. b labelled. b build. view signalUpdate].
"Add a button menu to the view" view addMenu: 'Generate new data' callback: [ fillView value ].
"We want some data when opening the view" fillView value. view -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Let us know if you have any further question

Hi everyone! I'm Agustin. I'm new at the Pharo/Moose community, so this
is my first post.
I'm playing around with Roassal (which by the way, I found really
interesting), and my goal is to have a typical chart (let's say piechart, or barchart) that updates dinamically as the data arrives.
I cannot figure out how to do this, without replacing the full data set
and creating the instance again.
So, if I build this chart:
b := RTPieBuilder new. b interaction popup. b objects: #(10 4 1 2 5). b slice: [ :aNumber | aNumber ]. b normalizer distinctColor. b labelled. b build. ^ b view.
then if I update the objects collection
b objects: #(15 5 3 20 31 7 8).
the only way to reflects the change in the piechart is to create a new
instance.
Does Roassal provides any functionality for doing this and am I missing
something?
Thanks in advance!
