3595 :: Need help with GUI and data visualisation (charting/plotting) in Nim

  Hi. Is there somebody, who works with data visualisation and have a success experience in this theme with Nim? I'm looking for gui-frameworks or libraries, who provides to make a GUI interface with Data Visualization. For example application for displaying a spectrogram or osciloscope.

  I'm found:

  • QtCharts+QML it cant be used in Nim via nimqml . But I think that it's too bad for my target, because it do copy of data for visualization (I can't find how to pass pointers to my X and Y arrays)
  • QWT+QML - looks pretty good, but I don't understand how to use from Nim and can't find any way to do it.
  • Gtk+Glade - Nim have a several libraries to bind gtk2/gtk3 and Glade. But I can't find a good charting/plotting widgets for these. I'm found the library matplotlib, but it written in Python and I can't find way, to use it in Nim.
  • GNU Radio (Gtk/Qt) - have widgets for Qt and Gtk, but only for Pyhton (and I can't find way, to use it in Nim, again)
  • gnuplot+Canvas(Gtk/Qt) - have a bindings for Nim, but only generates a plotting images and it looks bit strange. somebody did interactinve application (zoom, scrolling) with a visualization of huge data via this library?

  ---

  Shortly: I'm want to write a simple GUI app with scrollable plot and 2 buttons zoomIn and zoomOut (something like an oscilloscope) as a test application (app for checking, can I use Nim in my work or not; and whether it will take a lot of unnecessary effort). Please share your experience or advice in this topic. Many thanks!

  The easiest way is to wrap Facebook Visdom

  You can see a wrapper in arraymancer-vision. The Visdom code is only 60 lines.

  UPD: just now found gtk widget GtkDatabox (maybe it works with Gtk3) and gtkmm-plplot. both haven't wrappers for Nim, yet

  mratsim, thanks! (but arraymancer-vision it's something lika a gnuplot, I think)

  Arraymancer-vision was just a proof of concept to do image analysis with Arraymancer back in October.

  The important thing was how easy it is to start a visdom wrapper. Here Arraymancer-vision just wraps image display but charts should be easy as well.

  Facebook Visdom is a server that you can access from your browser. It has an API accessible from any language with HTTP queries and it is used for data visualization at Facebook. It's based on Plot.ly which is a very nice concurrent to matplotlib in Python and ggplot in R.
