Hi! We will soon have to change our bug trackers. What about taking this opportunity and moving to GIT? Some people have already cloned Roassal on github: https://github.com/search?utf8=✓&q=Roassal <http://github.com/search?utf8=%E2%9C%93&q=Roassal> We cannot ignore this… Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Labels on X

by Demian Schkolnik

Hi all! I want to make a little graph of a vector, with bars: | b ds labels | b := RTGrapher new. b extent: 300 @ 200. ds := RTStackedDataSet new. ds points: { 2 . 2.3 . 1.2 }. ds barShape width: 40. b add: ds. labels := #(x y z - -). b axisX numberOfLabels:labels size-1. b axisX numberOfTicks:labels size-1. b axisX labelConvertion: [ :item | labels at:item +1]. b build. ^ b view The code above writes the x 2 times. I just want an x, y and z under each one of the bars. Also, I havo to do the 'item+1' thing because it somehow starts at 0, and smalltalk arrays start at 1... Thanks!

Issue 1119 in moose-technology: progress bar when using the force based layout

by moose-technology＠googlecode.com

Status: New Owner: ---- Labels: Type-Defect Priority-Medium Component-Roassal New issue 1119 by alexandr...(a)gmail.com: progress bar when using the force based layout https://code.google.com/p/moose-technology/issues/detail?id=1119 An alternative is to have another subclass, such as RTForceBasedWithProgressBarLayout But this is not idea, because the progress bar should be by default Pharo. And on VisualWorks no. Another alternative, and the cleanest one I believe, is to have event generated to every X steps. You can have whatever you wish as a callback, moving the progress bar or not.

[Roassal 2] updating CompositeShape

by Jan B.

Hello I am trying to work with composite shapes, but I encountered a problem. Let's say I need to create a circle... and in the center of it is another, smaller, circle with label (but I need it to be centered according to both label and smaller circle, that's why I decided to use composite shapes instead of RTLabelled). I am able to create it just fine, problem is when I call update on its RTElement. I'm not sure whether I am even supposed to do it, but I think I should be. I start with just the inner circle with label: | composite view | composite := (RTLabel new text: 'label'; yourself) + (RTEllipse new size: 10; yourself). composite horizontal. element := composite element. view := RTView new. view add: element; open. element update. Before element update, it looks fine, but when I call update, composite layout (horizontal) gets lost. Let's say I can ignore this problem (which I can't), and I will try the same thing with whole shape | composite view subcomposite | subcomposite := (RTLabel new text: 'label'; yourself) + (RTEllipse new size: 10; yourself). subcomposite horizontal. composite := (RTEllipse new size: 50; color: Color transparent; borderColor: Color black; yourself) + subcomposite. element := composite element. view := RTView new. view add: element; open. element update this time I get exception MessageNotUnderstood: TRCompositeShape>>text:on: I will appreciate any help, either by fixing something if it is broken, or explaining how to reach my goal the correct way.

The Grapher charting engine

by Alexandre Bergel

Dear all, As many of you know, Grapher is a über-cool charting engine, part of Roassal. For people who do not know what Grapher is, here is a (compelling we hope) example: Which is obtained by the following script: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | b colors points ds pts dec lb | b := RTGrapher new. colors := Array with: Color red with: Color blue. points := OrderedCollection new. colors do: [ :c | ds := RTStackedDataSet new. pts := ((1 to: 100) collect: [ :i | 50 atRandom - 25 ]) cumsum. points add: pts. ds points: pts. dec := RTDevVarDecorator new. dec moveBehind; desviation: 0.5; color: (c alpha: 0.3); points: pts. ds connectUsing: (RTLine new color: (c alpha: 0.5); width: 1 ). b add: ds. b addDecorator: dec. ]. b axisX; axisY. b build. lb := RTLegendBuilder new. lb view: b view. colors doWithIndex: [ :c :i | lb addColor: c text: 'Series ', i printString ]. lb build. b view @ RTZoomableView. b view -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= In our grand vision of making Roassal the best visualizing engine of the Universe (we also know to be modest time to time, but not today :-), Grapher will play a very important role. We would like to stabilize Grapher and make it sure it happily fits everybody needs. You can help on it: - When you are tempted to look at the dark side of the planet (this is where R, JFreeChart, gnuplot, D3 and all their friends live), let us know. We will make sure to make you are happy again. - Share your wishlist with us. We already have a long todo list, but your opinion does matter and will take it seriously - we are open to contributions, which could be financial, bug fixe, enhancement, or simply encouragement. I am very happy to be surrounded by very smart engineers. Your encouragement are making them happy :-) Cheers, Alexandre, in the name of the Object Profile Team NB: sorry for the cross-list posting, but this email is very important for us, and for you we hope. -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Array does not show its content, just number of items

by Jan Kurš

Hey, I usually inspect a lot with arrays and since recently, I don't see really an array content, just number of items, eg: #( #('a' 'b') #('b')) -> inspect an Array [2 items] an Array [1 item] Instead of: #( #('a' 'b') #('b')) This is -- for me -- super-annoying. do you think an original functionality can be returned back, or you have some serious reasons to have it like this? Cheers, Jan

Mapping graphs on a open street map
