This may seem a little over simplistic, but the basics of what NumPy and Pandas offer can be achieved with the standard Smalltalk collection hierarchy. If your data fits in memory, then Pharo will handle the job. If not, then GemStone may do the trick.
That said, there’s a bunch of quite specialised stuff in those libraries, some of which is not trivial to implement. Or you may have gigantic existing datasets that you want to leverage. So you can always call the python libraries directly from Smalltalk using the PythonBridge [1]. It’s been a long time since I’ve used it, so hopefully someone else can let you know if it’s still well maintained. There are a bunch of options for plotting. Maybe start by checking out Roassal [2]. You may even want to check out Glamorous Toolkit [3]. It may change your life ;) [1] https://objectprofile.github.io/PythonBridge/ [2] http://agilevisualization.com <http://agilevisualization.com/> [3] https://gtoolkit.com <https://gtoolkit.com/> > On 15 Jan 2023, at 12:10 pm, Juan Cruz <juan.c...@outlook.com> wrote: > > Hello, > I hope everyone is doing well.
