You could try using a point-label or a function-label with a point size of 0,
like this:
(plot (list (function-interval sin (lambda (x) 0))
(function-label (lambda (x) (* (sin x) 0.2)) -1.8 "sin(x)"
#:point-size 0))
#:x-min -2 #:x-max 2)

Well, the contract should be that the number of elements in the output list
should be the same as the number of elements in the input list. I'm not sure
how that would be expres
Hi all,
I am creating some graphs where I want to label various regions as region A, B,
C, and so on. Currently I am doing this by coloring the regions differently and
having the labels in legend:

(function-interval (lambda (x) 0) MD 0 E_x #:label "F
Is there a contract we could add somewhere?

Your tick format function returns less labels than the number of items in the
pre-ticks. It should return one label for each pre-tick object (I just printed
out the lengths from the function to find this out.)
To fix this, I replaced the format function with
(for/list (((t idx) (
With a helpful pointer from Dupéron Georges I found the
protocol-buffer compiler and managed to create the messages I needed.
I have things working now, but one (hopefully final) issue: I can

it on the other end, but so far I ha
Maybe it's in /Users/dstorrs/Library/Racket/bin, or something like this?
otherwise, this command shoul hopefully show the file's path if it is on your
system:

Hi all,
I'm trying to write a `string-ticks` function to have arbitrary strings on
the (y) axis.
It mostly works, but as soon as I try to zoom by selecting a rectangle
*that touches upper left corner of the plot frame* DrRacket's interaction
window goes crazy and I have to restart it.

Bonjour,
Je débute en racket aussi, donc mes commentaires ne vous seront pas forcément
utiles :-)
Quelques considerations generales:

You need to break down your problem in smaller pieces.
Here is a suggestion of some helper functions to get you started.
digit->image : number -> image
Given a digit (0,1,...,9) as input, return an image of that digit.
number->digits : number -> listof-numbers
Given a natural number return
11 matches
