Re: [Pharo-users] Named edges and nodes in a Roassal graph

by Offray Vladimir Luna CÃ¡rdenas

Thanks Peter and Alexandre for your quick answers and interest, First, there is now a blog post with your solution and the lessons learned on our workshop about the dynamics of it and some improvements to be done to agile visualizations here: http://mutabit.com/offray/static/blog/output/posts/medios-en-colombia.html Is in Spanish, because is directed towards the local community, but some Spanish speaking devs at Pharo/Roassal could also take advantage of it and comment the ideas feedback them to the development process. Second, some inline comments below.

Awesome is easy to install and quick to use, and you get beautiful images! 2. Where the data comes from? When I explain that most of it comes from code inside pharo (relationships on the source code) or from things like buildEdgesFromObjects: (1 to: 20) from: [ :n | n // 3 ] they hit the first wall. So, what is needed is to preserve the awesomeness of complex beautiful visualization while making a bridge that takes the newbies from where they are towards that visualizations. Take for example the graph chapter[a] and imagine that after all the current, complex and beauty visuals that work as a panoramic view of what can be done (in a small gallery, for example, with source code linked to it), we start from the basics and away from the specifics software analysis. Saying something like (linking your basics to the graphs chapter): =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Graphs can represent a lot of relationships. The previous gallery is made using the internal relationships in the agile visualization platform software, but we can take other relationship. For example: "Processing a small TSV table" tab := RTTabTable new input: 'id origin relation destiny 1 Orange is a Fruit 2 Apple is a Fruit 3 Apple has color Red 4 Rice is a Cereal'. and lets build a graph small graph of this data: [...] =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- [a] https://dl.dropboxusercontent.com/u/31543901/AgileVisualization/Graph/0204-… Woud be nice to have an easy way to add tabular data, may be using GT support for table like interfaces (as I suggested in the blog post) so the recollection of data to make a visualization and the visualization code can be linked together more fluidly. In this way we can keep a balance between awesomeness and easiness. >> - Would be nice to have tools for all Roassal visualizations like export as svg.

The idea of putting it on GT seems the proper way to do it. The current way of using external tools to take screenshots or the mysterious way that uses the internal tool of Pharo or code messages are not friendly. A explicit button/menu with explicit options to store the images or a notification about where they are saved are the way to go for newbies. >> I would like to post the working example on the meetup page, so if any can tell me why the example is broken or how to solve it, would be nice. > > How can we help? You have already done. Keeping this conversation on the list and/or on the blog is a way to help and is nice to help back. I will be in another hackaton this Friday related with GT (not with data visualization) and another one on Dec. 6. I will keep you informed about how they went and how can be made better.

TextModel arrows controls

by Mark Rizun

Hello! I stumbled on a strange problem, when was using TextModel widget. The problem is that I can't control I-beam pointer with arrow keys inside of TextModel. They just do not work. Maybe I have to set some methods?

Yes, you are right. This is an option that should be provided by GT I think. We are working on that.

This is done in the Graph builder. If you are not using it, then do not worry.
