<div dir="ltr"><div class="gmail_default" style="font-family:courier new,monospace">Hi Neil, I have the 32-bit version installed on my Win7 machine at home, too. I was able to reproduce my own problem here as well. When I run your example, the first plot looks like I'd expect. The second one does not have the circle. If I remove the \circ from the text-extent it doesn't change anything. If I remove \circ from the text-extent and the draw-text, then the circle appears. If I remove \circ from only draw-text (leaving it in text-extent), the circle also appears. I did take a screenshot if you want to see it. Otherwise, the numbers are 39.0 13.5 2.5 0.0 31.0 13.5 2.5 0.0 </div><div class="gmail_default" style="font-family:courier new,monospace"> I then uninstalled the 32-bit version, downloaded and installed the x86_64 version, and reran your example. The same thing happened again. Something maybe helpful: when the \circ is in the string for draw-text the text is NOT rotated 90 degrees counter-clockwise. When the \circ is removed, the text is drawn rotated 90 degrees counter-clockwise. ...Ah, I see Kieron has uploaded an image to show. That is exactly what I see. </div><div class="gmail_default" style="font-family:courier new,monospace"> Deren </div></div><div class="gmail_extra"> <div class="gmail_quote">On Fri, Apr 25, 2014 at 6:39 PM, Neil Toronto <<a href="mailto:neil.toronto@gmail.com" target="_blank">neil.toronto@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I can't replicate this problem on my machine, so I'll need more information.

Racket 6.0 32-bit on 64-bit Windows 7. Using DrRacket. The plot frame is generated, the plot title and x-label appear, the tick marks on the axes appear, but the y-label doesn't appear and neither (points ...) nor (function ...) appear. Example code (hopefully the extra characters come through email correctly): #lang racket (require plot) (define (make-p title y-label) (plot (function (λ(x) x)) #:x-min 0 #:x-max 50 #:y-min 0 #:y-max 50 #:x-label "X (⇑∘C)" #:y-label y-label #:title title)) (define-values (works doesnt-work) (values (make-p "Works (⇓∘C)" "Y (C)") (make-p "Doesn't Work (⇓∘C)" "Y (∘C)"))) works doesnt-work ;;;;;;;;;;;;;;;;;;;;; It's not just arbitrary character substitutions, for instance all the \left|right|up|downarrow don't cause any problems, but \Down|Up|etc.arrow causes the same problem as \circ. I threw some in the title and x-label to show that they didn't cause any failures. I've attached an image of what appears in case it helps.
