i'm not using drscheme.
how do i display things like

which are produced when we use plot etc.
if i run a racket program from command line?
i thought there might be something like a show function, but it doesn't
seem to be in
#lang racket
Start your interactions with `(plot-new-window? #t)' (without the
quotes). Every call to `plot' or `plot3d' will then display the plot
in a new frame.
It sounds like you don't need programmatic control over the frames,
but if you do, use `plot-frame' and `plot3d-frame'.

thx neil (and azumu).
there doesn't seem to be a
plot-new-window?
or
plot-frame
after i do
(require plot)
aren't these functions part of plot?
nor does it help if i change
#lang racket
to
#lang slideshow
for instance, this program doesn't work in drscheme:
#lang slideshow
(require plot)
(plot-font-size (current-font-size))
(plot-width (current-para-width))
(plot-height 600)
(plot-background-alpha 1/2)
(slide
#:title "A 2D Parabola"
(plot-pict (function sqr -1 1 #:label "y = x^2")))
because it doesn't know what plot-font-size or plot-width is.
the program is from:
http://docs.racket-lang.org/plot/plot2d.html?q=plot-frame#%28def._%28%28lib._plot/main..rkt%29._plot-frame%29%29
so what am i missing here?
(i'm on debian, but have installed racket v5.1)
Oh, that's the problem. I added all those plot goodies in v5.2, when I
reimplemented it in Racket. I hope you're not stuck with v5.1. :/
