Re: [Bug-apl] Plotting data

[Juergen Sauermann]

Hi,

,(⍕⍪DATA),⎕UCS 10

should give a string that you can write to a file via the file_io function.

You can then call gnuplot with that file, either externally or with )HOST or with AP100 from APL.

Yeah, gnuplot is good. What I need is a simple way to ship off a matrix to gnuplot using a single operation. I can do that using Emacs now, but would it make sense for me to build something that allows a user to do it directly from the interpreter?

Elias

Hi,

I personally like gnuplot very much. The latest versions can also generate html output
so you can put your data on the web (even live if you use a combination of apache web server,
calling an APL CGI script, calling gnuplot).

Don't know anything about the other options, though.

In my attempt to start using GNU APL for more than learning and use it for real purposes, I wanted to use it to process performance data from benchmarks here at work.

This leads me to the need to visualise the data. Systems like R have "plot" commands that can plot any dataset. Obviously I want to do the same in APL.

Of course I wanted to implement a native library that hooks GNU APL into some existing graph plotting tool. Before I started doing that, I figured I'd ask for opinions first.

There are a few options:

• Simply run gnuplot as an external backend
• Use the plplot library
• Interface with R
• Use another library that I don't know about yet
• Write it from scratch

Any suggestions as to what to do? The gnuplot solution does feel appealing, since it's available pretty much everywhere.
