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

Heinrich, you hit the nail on the head. for an interactive plotting story to work well, we wind up needing to have better tools in the ecosystem on the gui / computational notebook side. on the other hand, similar work was done last summer, as heinrich mentions, in the form of ghc live https://g

Hi Hienrich, It is indeed a big scope as you mentioned. Matlab has been working for years to get this functionality right. On the other hand, the project you linked is interesting. For me it would already be a huge advantage if I could edit and re-evaluate expressions interactively (in a comfortab

Hello Ernesto, There are a number of efforts underway to provide better data vis libraries for haskell. Likewise, there was some recent discussion on the Diagrams mailing list about data vis tooling, and there should be a few interesting tools surfacing over the coming few months. My immediate c
