Another toy to play with...

[Chris Moller]

    ... or maybe a polished-up version of an old toy: 
      aplplot, which I wrote several years ago.
      
      Aplplot uses the plplot package to produce plots in a number of
      formats:  standard x-y, polar, and 3D projection at the moment,
      and more can be added later.  It can put the plot on your screen
      or dump it to file in a variety of formats.  If you're using
      aplwrap, it can embed the plot in the aplwrap window.
      
      Originally, the plot options were set by a string left argument
      containing keywords and values:
      
    
> 'bgwhite;xcol 1; tlabel "Lissajous axis
>         1"' plot ⍉2 128⍴(1○2×(⍳128)÷6),2○(⍳128)÷6
>     
    
      That hasn't been precisely ideal so version 2.0 has a menu
      interface, which makes it a lot easier to use:
      
    
> 'menu' plot ⍉2 128⍴(1○2×(⍳128)÷6),2○(⍳128)÷6
>           
>         
    brings up a GTK-based menu that lets
        you set all the various parameters.
        
        (The string i/f is still there, which can be handy for doing
        things like:
      
> apl --LX
>           "'libaplplot.so' ⎕FX 'plot'" --eval "' file sine.png; tlabel
>           Sine' plot 2○(⍳128)÷6"
>     
    which will create a PNG file showing a bit of sine curve.)

    if anyone wants to play with it.  There's a bit of a description in
    the README and some examples at:

    Have fun,
