Glamour fixes for Pharo 4.0
by Usman Bhatti 03 Dec '15

03 Dec '15

Hi, According to what was agreed, the fixes for stable version of Moose 5.1 should be committed into the repository created for this purpose (Moose/Moose51) and they should not go in the main repo (moose/Glamour). Unfortunately, some fixes have been committed in the principal repository for fixing issue # 1126, which deviates from the agreed conventions and creates a parallel versions. The principal repository (Moose/Glamour) handles the development commits, the fixes for Moose version XY go to Moose/MooseXY and the stable version of the configuration loading the packages is updated (e.g., see 3.1.3-Moose51 in ConfigOfGlamourCore). [image: Inline image 1] In addition, the fixes should be referenced in the proper configuration dedicated for the fixed packages. Glamour-Morphic-Renderer is loaded by ConfigurationOfGlamourCore so ideally the fixes should have been loaded in the stable version of the config. The fixes are loaded by ConfigurationOfMagritteGlamourForPharo40 and it becomes very difficult to trace the origin of the package in the image. Thank you for adhering to what was agreed on the mailing list. Moreover, the fix creates an issue with embedding EditableDropListMorph in Tabulators but we will only be able to correct the error once we have resolved the problem of parallel commits and correctly loading them. regards.

Editing methods in the inspector
by Alexandre Bergel 01 Dec '15

01 Dec '15

Hi! If I inspect a compile method, I have a tab showing the source code. But I cannot modify the source code of it (well, it does not compile). Is there a way to edit compile method within the GTInspector? Maybe using Ring?

Stack visualizations
by Hernán Morales Durand 30 Nov '15

30 Nov '15

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

Matrix sunburst: increasing the separation between arcs
by Offray Vladimir Luna Cárdenas 27 Nov '15

27 Nov '15

Hi, Pair programming with Milton at Smalltalks 2015, we (well mostly he) came with what I call a "matrix sunburst" that shows a sunburst diagram using a matrix instead of a tree as data source (the clever hack of Milton was to convert the data in the matrix to a tree with only one child on any branch after the first one!). The inspiration was taken from [1] and the idea was from a friend who want to use this kind of matrix alike sunburst to compare public medicine information. [1] http://www.theguardian.com/world/interactive/2012/may/08/gay-rights-united-… With this I can create thinks like this: But to get a more readable visualization, I would like to make two things: a. Increase the empty space between arcs, not like the current radial strategy, but more like the graphic at [1]. For this we thought in adding a RTEdge with the same color as the background. How can I calculate the position of every RTEdge at the final of each arch in the sunburst? b. I would like to keep each ring of the same size instead of making them narrower as the become more away of the center. It this possible? c. Finally I have created RTSunburstBuilder>>exploreMatrix: aMatrix coloredWith: aColorPalette in my own image, because I think that is the best place it can be to be reused in my own visualizations. Is this a good practice? Can I share this code back with the Roassal project? How? (hopefully I will not need to learn git and its gratituous complexity). Cheers, Offray

CircularTreeMaps
by Usman Bhatti 27 Nov '15

27 Nov '15

Hi, I am trying to use exampleClassHierarchy in RTCircularTreeMapBuilder for visualizing some packages and classes. First, I think the borderWith: should be a fraction of what already is defined in the examples, otherwise the borders are too think to visualize anything correctly. Second, the borderWidth is proportional to the radius of circle. Is this intended? To reproduce, here is an example + screenshot: | b | b := RTCircularTreeMapBuilder new. b shape color: Color transparent; borderWidth: 0.01; borderColor: Color black; if: [ :cls | cls subclasses isEmpty ] fillColor: [ :cls| (Smalltalk includesKey: (cls name, 'Test') asSymbol) ifTrue: [ Color green ] ifFalse: [ Color purple ] ]. b baseradius: 400; weight: [ :cls | cls withAllSubclasses size]. b explore: RTObject using: #subclasses. b build. ^ b view open [image: Inline image 1]

Hi! Some students from Arizona State University are analyzing some tweets. This is pretty cool.

Trying to display local ancestry inference with Grapher
by Hernán Morales Durand 24 Nov '15

24 Nov '15

Hello, I am using Roassal2 (StephanEggermont.40) in Pharo 4. The attached picture displays a common visualization for inference of local ancestry in population genetics, I have attached what I am getting now with Grapher. Input data for such visualization is for example: 1:454 2:1488 1:2546 2:5711 1:14253 2:24411 1:31490 0:41585 (those are like Associations with key 0, 1 or 2 and value 454, 1488, ... etc) In the attached picture Min X is 0 and Max X is 41500 so the X axis (chromosome positions) is rendered in intervals between 10000. This is what I am trying now (code is commented where I tried to configure X axis interval) | b intv | intv := 0 to: 40000 by: 10000. b := RTGrapher new. ds := RTStackedDataSet new. ds dotShape color: Color red. ds points: #(1 2 1 2 1 2 1 0); x: intv. "????" ds barShape width: 99; color: Color red. "b minX: 0; maxX: 41500." b add: ds. b axisX noLabel; noTick. b axisY noDecimal. b build. I have some questions: 1) There is support to add an interval label to the X axis but preserving the space relation with the real chromosome position (the X axis) for the data (points in my example = 454 1488 2546 5711 14253 24411 31490 41585)? 2) How to clear the bar filling? Any advice or help would be really nice. Hernán

[ANN] JavaScript to MSE
by Alexandre Bergel 20 Nov '15

20 Nov '15

Hi! Hernán, PhD student from Argentina working with Santiago V., has produced a JavaScript -> MSE translator. This is still a very early effort, but it looks like to work reliably. We were able to produce MSE for a couple of JavaScript applications. Hernán is working on a webpage for his exporter. He will advertise it soon. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
