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.
Nice work.
I will reply about improvements separately.
Cheers. Doru

Yes please ...
I am curious:
- what are in your opion the biggest gaps to close. - what are the short, mid and long term goals.
Ever thought of a "feature-based" bountie system to get money?

or something like "bountysource" https://www.bountysource.com/
Indeed… Would be great! We will look into this!

There are difficult questions. I think (but maybe I am wrong), that the web will play a very important role. Being able to have interactive visualization on the web is highly important. Even for Pharoers: many are embedding Roassal-made visualizations in seaside applications. In addition of using a cool programming environment, there is a big advantage of using Roassal over other systems (D3, RaphaelJS, …): - The visualization is made in Pharo and JavaScript HTML5 code is generated. So, in principle, this should be more memory efficient than using a JavaScript library. We have not made any benchmarks for this so far. But we envision Roassal-made visualization to be mobile-over-poor-internet-connection friendly.
Our short term goals is: - continuing to fix bugs and stabilizing the system. We will avoid having big-bang or major feature implementation. Stabilizing is important.
Our mid-term goal is: - publishing AgileVisualization.com as a real book
Our long term goal is: - offering a rock-solid platform for data visualization - generating super-compact JS/HTML5 code - be better than competitor libraries in terms of speed and memory consumption when run in a web browser.

The email we have sent recently to the ESUG mailing list goes in that direction. It is important for us that users show their support. This helps keeping the moral high and making sure we have the financial support to continue developing Roassal.
I am personally fully committed to Roassal. This means that my employer (the University of Chile) cannot make me change the focus of my research or work. So I am working on Roassal, and will continue to do so for quite some time. I am lucky to be surrounded by a wonderful and highly competent team of software engineers. Roassal will have a long life! :-)

i think you are right.
But I still set my focus on Standard Clients (Workstation). Pharo is so small and easy to install and the Pharo environment is perfect for small tool projects.
What about Roassal3D? I leally like the 3D City Metapthor for visualizing enterprise application landscapes. Is this path dead?

No, it is not. It is just the lack of financial resources. We would like to push that very much. But currently we cannot.
As i mentioned earlier: The "Pharo Consortium" (?) should set up a "feature based" bounty / donation system ... i am sure for a good & maintained 3D Lib in Pharo and on top something like Roassal3D we will find some sponsors.
Does this make sense?
btw: Ever seen three.js? Really impressing.

Wow!
Indeed, impressive! We still have a lot of work to do

Yes. Although RTDevVarDecorator is not rooted into strong maths. It was more an experiment. If you look at the class RTDevVarDecorator, you will see it is quite simple. Adding decoration in a chart made with Grapher is very simple.
