Re: [Haskell-cafe] GSoC proposal: Data Visualization

Dear All, Data visualization for hMatrix is basically my main objective, but I would like to be flexible in the following ways: * Have generic approach so other data types can be visualized with my library as long as the necessary instances are present. * Define a generic standard to represent values in multiple types of plots. This way graphics output can be easily extended for more back ends (gtk, qt, gnuplot). I am looking for alternatives. I will check GuiTV definitely, but currently I am considering the possibility of plotting data via javascript as suggested by Dough and using Haskell just to generate the values. I am using ghclive (https://github.com/shapr/ghclive) as fronted since the project looks nice and might be worth continuing it. Do you think there would be big objections if I continue working with that project since it was built for last GSoC? Best regards, Ernesto Rodriguez

For me it would already be a huge advantage if I could edit and re-evaluate expressions interactively (in a comfortable GUI, not ghci). Also a plot widget with sliders would also help. I was wondering if you know any reason the project has not been worked on for various months (as I see in the repo). Is there anyone working in this project and has a later version? I mean these are features that are even available in free math packages such as Sage.

I was actually the initial mentor for this project. I'm not particularly happy about the result. As you can see, it hasn't been picked up by anyone else, including me, and I think that's because it missed the modularity goals I had in mind.

Indeed interactive notebook functionality is missed by many :-).

Is it a good time to ask about current status of GuiTV, which is possibly second closest to what Ernesto had in mind? http://www.haskell.org/haskellwiki/GuiTV Would be possible to ask Conal Elliot whether he is interested in mentoring a project that would add widget(s) for hmatrix visualisation?

PS I believe Johan Malmström http://homepage.mac.com/jmalmstrom/'s HaXcel project, which may have tried to implement a similar functionality with a spreadsheet interface is dead: http://www.mrtc.mdh.se/projects/Haxcel/ -- Best regards Michal
