When a digital function is defied by two boxed vectors y1;y2
And you want to fid a linear interpolated value between two values
of the first vector the function x interp y1;y2 will give a linear
interpolated value for each left arguent
interp =: 4 : 0"0 _
assert. 2 = # y
'a b'=. y
ai =. {.
Concerns about using %. For solution of linear regression models avoid the
need in nearly all applications to do some careful diagnostics after the
calculation. Regression is one of the main tools I use J for and the simple
function listed below returns a result and sufficient information ab

Perhaps Plot should support ternary graphs. If I were doing this myself, I
might draw the graphs without using Plot.

I have constructed a large number of ternary plots in J, but have not been

All of the defaults for grids and tics are inappropriate and eliminated with

I can confirm that the script works fine with Jqt.
However it does not work with J console, producing only the first plot.
Henry's suggestion does not work in J console either.
A standard plot call

Jeremy,
Sometimes mixing tacit and explicit definitions gives very simple programs
especially if you want to use a conjunction like power
gen1 =: 4 : 'life^:(i.>:x)y'
gen2 =: 4 : 'life ^:x y' if you only want the final result
