Hi Alex, After the Pharo and Moose release I will get back to you with feedback. Cheers, Doru On Fri, Mar 20, 2015 at 10:18 PM, Alexandre Bergel <alexandre.bergel@me.com> wrote:
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.
