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 Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. is my first post. interesting), and my goal is to have a typical chart (let's say piechart, or barchart) that updates dinamically as the data arrives. and creating the instance again. instance. something? _______________________________________________ Moose-dev mailing list Moose-dev(a)list.inf.unibe.ch https://www.list.inf.unibe.ch/listinfo/moose-dev
